Water spillage from reservoirs: Is CEB to blame?

Published

on

Let us examine the facts

By Chris Ratnayake

‘The pen is mightier than the sword’ is an old adage. However, it has gained new currency in today’s world where mass communication, in the form of press and other media, greatly influences public opinion. Consequently, this valuable tool can become lethal in the hands of some who lack professional competence to understand what they write about, are unable to comprehend the relevant issues or analyse relevant data of a complex technical problem. Such an issue has arisen with respect to the water spillage that occurred last month in our hydroelectric reservoirs.

I refer to three articles in The Island recently by Dr. Vidhura Ralapanawe, G. A. D. Sirimal, and Ifham Nizam, alleging mismanagement and even corruption simply because water was spilling, and thermal plants were operating simultaneously. No additional data or analysis was presented. As a professional engineer, with 23 years of experience at the Ceylon Electricity Board (CEB), focusing on power system planning, and some 30 years’ experience as a Senior Power Engineer at the World Bank, reviewing power sector operations in about 17 developing countries, I could well see the fallacy of these accusations. However, I soon realised that the general public appears to accept the validity of these accusations at face value. Public officials are fair game, any article alleging inefficiency or dishonesty is readily believed without any examination of the merits of these articles. I therefore decided to research the relevant facts and submit the findings in the hope of correcting the grave misinformation propagated.

Facts

Any professionally competent article, addressing the subject, to determine whether there was any inefficiency or miscarriage of duty should have considered the following:

1. Responsibility for water level management:

The articles place the sole blame for spillage on the CEB’s system control centre (SCC) engineers. They seem to be unaware that water level management of the main reservoirs (namely the Mahaweli complex) is the responsibility of the Water Management Secretariat (WMS), not the CEB. WMS has representation from the CEB, Water Board, Irrigation, Mahaweli, and more. The release policy, every week from every reservoir, is issued by the WMS and the CEB cannot store or release water through a unilateral decision. So, the accusation on the CEB is misplaced!

2. Drawdown curves:

These are optimum water level charts, developed based on years of past experience and specialised computer programmes designed to optimise the often-competing demands of agriculture and power, which guide system operators in the management of reservoir water levels. To determine any possible mismanagement, one has to prove that, for sustained periods, the drawdown did not correspond to these curves, subject, of course, to the current rainfall expectations and plant capacities available for dispatch. This is a complex exercise that the writers of these articles appear to be ignorant of.

3. Optimal dam design envisages some spilling:

Occasional spillage in a few years is no indication of mismanagement. Reservoirs are designed and constructed to optimise the competing demands of costs and benefits. In fact, if water never spills, it is a sure indication of bad design and excessive investment on taller dams, inundating larger areas of land than necessary! The articles never examined whether such spillage was a regular occurrence or a one-off after many years.

4. Reservoir heights deviated from optimum:

It may be noted that in some instances the reservoir heights were reduced due to complaints of inundation of affectees, making spillage unavoidable. Clear examples are Kukule (2002) and Upper Kotmale (2012), pruned down to mere ‘ponds’ and not storage reservoirs owing to public protests. Expert hydrologists and the CEB engineers said, at that time, that if Kukule was allowed to be built as a full capacity reservoir, frequent flooding of Kalawana and Baduraliya, sometimes with severe loss of life, would have been avoided. Raising the Kotmale dam for greater storage has been suspended due to protests. We can’t have it both ways: Avoid spillage but refuse to allow the required dam height!

5. Difference between operational ponds and storage reservoirs:

Cascading hydropower systems have both storage reservoirs and operational ponds. The latter are built to enable a power plant to operate with some water storage for a short time period and function by the discharges from upstream plants, secondary inflows in the locality or releases from the main storage reservoirs. The levels of these small capacity reservoirs are not readily controllable and often spillage cannot be avoided.

6. Historical performance:

To do justice to the issue, I obtained historical data of reservoir performance from 2011 to 2020 which the CEB publishes with respect to each reservoir, and computed the extent of spillage as a percentage of annual inflows. It is observed that the spillage that has occurred is extremely minimal and as expected. The results of the 10-year study are as follows:

Laxapana complex:

0.044% in 2013, 0.029% in 2014, 0.002% in 2015, 2.741% in 2018, 0.327% in 2019. All other years zero spill.

Mahaweli complex: Spilling occurred only in 2016: 0.663% and 2018: 5.807%

Samanalawewa: Spilling occurred only in 2019: 3.333%

7. Maximum hydro capability vs system demand:

The mere fact that private thermal power plants operate during spillage, the sole basis of these articles, is absolutely no indication of mismanagement. Our maximum hydroelectricity capability is 1450 MW vs a peak power demand of about 2700 MW. The balance must necessarily come from other sources, mainly thermal power. Consequently, thermal power may be used even when spillage is occurring.

8. Contractual issues with respect to private (thermal) power:

The private power contracts are made with capacity charges payable, irrespective of output, when they are contracted (periods of 10 or 20 years are typical). Once contracted, the capacity charge must be paid, whether it is ordered to operate or not. Private power plants with active agreements and the CEB power plants are scheduled or ‘committed’, generally on the basis of monthly or weekly dispatch plans. The principal in scheduling is to achieve the lowest operating cost of the generating system as a whole, subject to meeting (i) water release schedules (ii) reliability of the transmission network, (iii) purchasing all electricity from renewable energy, whatever the price. Once ordered to operate, additional (variable) charges payable to private oil power plants are based on actual energy discharged and these are determined on the basis of agreed plant efficiencies (specified in the contracts) and CPC-announced current fuel prices. Hence situations may arise where it may even be more profitable to dispatch private power in preference to CEB’s own plants, as the efficiencies of some private thermal plants may be superior to the CEB’s own plants.

9. Contractual issues with respect to private renewable energy:

Since 1996, lucrative contracts were provided to private renewable energy on must-take contracts. Consequently, many situations may arise when private renewable energy power plants, including rooftop solar power, are dispatched and paid for while water is overflowing at the reservoirs. None of the renewable energy plants have any long-term storage capacities and must be discharged when available. The average rates for renewable energy plants for 2020 were: Rs 15.47 (mini-hydro), 16.79 (wind), 22.36 (solar), 22.39 (biomass), and 36.20 (Waste to energy) while the variable cost of the CEB’s own plants vary from Rs 6.78 for coal and 17.26 for diesel plants (Ref: ‘dispatch and fuel cost data’ published by the CEB). During the whole of October-November, one generator at Norochcholai was shut down due to very good rainfall. Financially, the implication is to stop producing at Rs 6.78 from coal (2021 prices are a bit higher) and purchase from private mini-hydros and other such sources at Rs 15.47 or more. So, the CEB reports losses; private mini-hydros report profits! While this may be acceptable due to environmental considerations, the financial impacts may be noted.

10. Exigency situations: The sudden rains last November in Sri Lanka was quite unprecedented.

Many areas, not adversely affected under normal circumstances, were flooded or subject to landslides. Tens of thousands were affected and many lost their lives. We know that such catastrophic weather patterns have occurred recently and are still happening in many countries around the world as a result of global warming. In all such instances the usual operating patterns have been disrupted. Even these considerations have escaped the imagination of the writers of these articles.

Have any of the above issues been analysed in these articles? The answer is a clear ‘no’ and clearly displays the absurdity of the accusations.

Responsible journalism

In the international press we often see articles written by journalists on highly technical subjects. This is acceptable to create a platform for healthy public opinion. However, such reputed journalists carry out extensive research and consult experts as well as the hands-on operators or practitioners. These are usually cited in the articles and give credibility to their contents. However, this is unfortunately not the case in Sri Lanka. Many journalists rush to print sensational stories without even bothering to corroborate basic information, as the above analysis clearly shows. None of the key pertinent facts have been checked or verified. To add insult to injury they also impute fraud and corruption! They also add catchy journalistic innuendos, leading the public completely astray. One article refers to ‘opening a pandora box’, an innuendo that lets the reader imagine massive corruption occurring within the CEB. Instead of imagining a ‘pandora’s box’ he should have studied the generation and water inflow/releases published in the CEB website and done the required analysis. Is this responsible journalism?

I may also add that it is not only such journalists who lose their way handling a complex engineering problem. Sometime ago The Island carried an article by an experienced engineer, who specialises in another field, unrelated to electrical engineering, who recommended pumped storage plants using water released for agriculture in the Mahaweli complex. In reality, this is an impossibility as (a) all pumped storage plants need to collect the water discharged in a storage pond immediately at the outlet and (b) water released for agriculture is widely spread out and can never be collected and pumped back to the head pond. This example further illustrates that complex engineering problems are best left to subject specialists and any laymen’s attempt to address such issues would require understanding and analysis of data and extensive consultation with experts, not simply a reflex action to what appears on the surface.

To right the grave misinformation propagated, I have placed the pertinent facts related to the issue for public scrutiny. It is left for the reader to judge: Is there any evidence that the CEB acted inefficiently or fraudulently, or are the accusations due to the lack of understanding in the subject, not attempting any analysis of the wealth of information available publicly in the CEB’s website, and the need for sensationalism?

Citizenship, Devolution, Land and Language: The Vicarious Legacies of SJV Chelvanayakam

Published

on

From left GG Ponnambalam, SJV Chelvanayakam and M. Tiruchelvam

SJV Chelvanayakam, the founder leader of the Ilankai Thamil Arasu Kadchi, aka Ceylon Tamil Federal Party, passed away 49 years ago on 26 April 1977. There were events in Sri Lanka and other parts of the world where Tamils live, to commemorate his memory and his contributions to Tamil society and politics. His legacy is most remembered for his espousal of the cause of federalism and his commitment to pursuing it solely through non-violent politics. Chelvanayakam’s political life spanned a full 30 years from his first election as MP for Kankesanthurai in 1947 until his death in 1977.

Under the rubric of federalism, Chelvanayakam formulated what he called the four basic demands of the Tamil speaking people, a political appellation he coined to encompass – the Sri Lankan Tamils, Sri Lankan Muslims and the hill country Tamils (Malaiyaka Tamils). The four demands included the restoration of the citizenship rights of the hill country Tamils; cessation of state sponsored land colonisation in the North and East; parity of status for the Sinhala and Tamil languages; and a system of regional autonomy to devolve power to the northern and eastern provinces.

High-minded Politics

Although the four basic demands that Chelvanayakam articulated were not directly delivered upon during his lifetime, they became part of the country’s political discourse and dynamic to such an extent that they had to be dealt with, one way or another, even after his death. So, we can call these posthumous developments as Chelvanayakam’s vicarious legacies. There is more to his legacy. He belonged to a category of Sri Lankans, Sinhalese, Tamils and Muslims, who took to politics, public life, public service, and even private business with a measure of high-mindedness that was almost temperamental and not at all contrived. Chelvanayakam personified high-minded politics. But he was not the only one. There were quite a few others in the 20th century. There have not been many since.

Born on 31 March 1898, Chelvanayakam was 49 years old when he entered parliament. He was not an upstart school dropout dashing into politics or coming straight out of the university, or even a hereditary claimant, but a self-made man, an accomplished lawyer, a King’s Counsel, later Queen’s Counsel, and was widely regarded as one of the finest civil lawyers of his generation. He was a serious man who took to politics seriously. Howard Wriggins, in his classic 1960 book, “Ceylon: Dilemmas of a New Nation”, called Chelvanayakam “the earnest Christian lawyer.”

Chelvanayakam’s professional standing, calm demeanour, his personal qualities of sincerity and honesty, and his friendships with men of the calibre of Sir Edward Jayatilleke KC (Chief Justice, 1950-52), H.V. Perera QC, P. Navaratnarajah, QC, and K.C. Thangarajah, were integral to his politics. The four of them were also mutual friends of Prime Minister SWRD Bandaranaike and they played a part in the celebrated consociational achievement in 1957, called the B-C Pact.

Chelvanayakam effortlessly combined elite consociationalism with grass roots politics and mass movements. He led the Federal Party both as a democratic organization and an open movement. Chelvanayakam and the Federal Party used parliament as their forum to present their case, the courts to fight for their rights, and took to organizing non-violent protests, political pilgrimages and satyagraha campaigns. He was imprisoned in Batticaloa, detained in Panagoda, and was placed under house arrest several times. His Alfred House Gardens neighbours in Colombo used to wonder why the government and the police were after him, of all people, and why wouldn’t they do something about his four boisterous, but studious, sons!

He was a rare politician who filed his own election petition when he was defeated in the 1952 election, his first as the leader of the Federal Party, and was rewarded with punitive damages by an exacting judge. He had to borrow money from Sir Edward Jayatilleke to pay damages. The common practice for losing candidates was to file vexatious petitions in the name of one of their supporters with no asset to pay legal costs. Chelvanayakam was too much of a principled man for that. As a matter of a different principle, the two old Left parties never challenged election losses in court, but Dr. Colvin R de Silva singled out Chelvanayakam’s uniqueness for praise in parliament, in the course of a debate on amendments to the country’s election laws in 1968.

Disenfranchisement & Disintegration

Although he became an MP in 1947, Chelvanayakam had been associated with GG Ponnambalam and the Tamil Congress Party for a number of years. GG was the flamboyant frontliner, SJV the quiet mainstay behind. Tamil politics at that time was all about representation. In fact, all politics in Sri Lanka has been all about representation all the time. It started when British colonial rulers began nominating local (Sinhala, Tamil, Muslim) representatives to quasi legislative bodies, and it became a contentious political matter after the introduction of universal franchise in 1931.

Communal representation was conveniently made to look ugly by those who themselves were politically communal. Indeed, under colonial rule, if not later too, Sri Lankans were a schizophrenic society where most Sinhalese, Tamils and Muslims were socially friendly, but politically communal. The underlying premise to the fight over representation was that British colonialists were not leaving in a hurry and they were there to stay and rule for a long time. Hence the jostling for positions under a foreign master. It was in this context that Ponnambalam made his celebrated 50-50 pitch for balanced representation between the Sinhalese, on the one hand, and all the others – Tamils, Muslims, Indian Tamils – combined on the other. It was a perfectly rational proposition, but it was also perfectly poor politics.

But independence came far sooner than expected. The Soulbury Constitution was set up not for a continuing colonial state, but as the constitution for an independent new Ceylon. So, the argument for balanced representation became irrelevant in the new circumstances. The new Soulbury Constitution was enacted in 1945, general elections were held in 1947, a new parliament was elected, and Ceylon became independent in 1948. SJV Chelvanayakam was among the seven Tamil Congress MPs elected to the first parliament led by GG Ponnambalam.

The Tamil Congress campaigned in the 1947 election against accepting the Soulbury Constitution and for a vaguely formulated mandate “to cooperate with any progressive Sinhalese party which would grant the Tamil their due rights.” But what these rights are was not specified. In a Feb. 5, 1946 speech in Jaffna, Ponnambalam specifically proposed “responsive cooperation between the communities” – not parties – and advocated “a social welfare policy” to benefit not only the poor masses of Tamils but also the large masses of the Sinhalese.

So, when Ponnambalam and four of the seven Tamil Congress MPs decided to join the government of DS Senanayake with Ponnambalam accepting the portfolio of the Minister of Industries, Industrial Research and Fisheries, they were opposed by Chelvanayakam and two other Tamil Congress MPs. The immediate context for this split was the Citizenship question that arose soon after independence when DS Senanayake’s UNP government introduced the Ceylon Citizenship Bill in parliament. The purpose and effect of the bill was to deprive the estate Tamils of Indian origin (then numbering about 780,000) of their citizenship. Previously the government had got parliament to enact the Elections Act to stipulate that only citizens can vote in national elections. In one stroke, the whole working population of the plantations was disenfranchised.

GG Ponnambalam and all seven Tamil Congress MPs voted against the two bills. Joining them in opposition were the six MPs from the Ceylon Indian Congress representing the Malaiyaka Tamils and 18 Sinhalese MPs from the Left Parties. The Citizenship Bill was passed in Parliament on 20 August 1948. Ponnambalam called it a dark day for Ceylon and accused Senanayake of racism. But less than a month later, on September 3, 1948, he joined the Senanayake cabinet as a prominent minister and the government’s principal defender in parliamentary debates. Dr. NM Perera once called Ponnambalam “the devil’s advocate from Jaffna.”

Chelvanayakam remained in the opposition with two of his Congress colleagues. A little over an year later, on December 18, 1949, Chelvanayakam founded the Ilankai Tamil Arasu Kadchi, Federal Party in English. Not long after, joining Chelvanayakam in the opposition was SWRD Bandaranaike, who broke away from the UNP government over succession differences and went on to form another new political party, the Sri Lanka Freedom Party. As was his wont as a Marxist to see trends and patterns in politics, Hector Abhayavardhana saw the breakaways of Chelvanayakam and Bandaranaike, as well as the emergence of Thondaman as the leader of the disenfranchised hill country Tamils, as symptoms of a disintegrating society as it was transitioning from colonial rule to independence.

Abhayavardhana saw the Citizenship Act as the political trigger of this disintegration in the course of which “what was set up for the purpose of a future nation ended in caricature as a Sinhalese state.” Chelvanayakam may have agreed with this assessment even though he was located at the right end of the ideological continuum. “Ideologically, SJV is to the right of JR,” was part of political gossip in the old days. He saw “seeds of communism” in Philip Gunawardena’s Paddy Lands Act. For all their differences, Chelvanayakam and Ponnambalam were united in one respect – as unrepentant opponents of Marxism.

The Four Demands

Chelvanayakam had his work cut out as the leader of a new political party and pitting himself against a formidable political foe like Ponnambalam with all the ministerial resources at his disposal. Chelvanayakam may not have quite seen it that way. Rather, he saw his role as a matter of moral duty to fill the vacuum created by what he believed to be Ponnambalam’s betrayal, and to provide new leadership to a people who were at the crossroads of uncertainty after the unexpectedly early arrival of independence.

He set about his work by expanding his political constituency to include not only the island’s indigenous Tamils, but also the Muslims and the Tamil plantation workers from South India – as the island’s Tamil speaking people. It was he who vigorously introduced the disenfranchised Indian Tamils as hill country Tamils. In the aftermath of the Citizenship Act and disenfranchisement, restoring their citizenship rights became an obvious first demand for the new Party.

Having learnt the lesson from Ponnambalam’s failed 50-50 demand, Chelvanayakam territorialized the representation question by identifying the northern and eastern provinces as “traditional Tamil homelands,” and adding a measure regional autonomy to make up for the shortfall in representation at the national level in Colombo. To territorialization and autonomy, he added the cessation of state sponsored land colonization especially in the eastern province. Chelvanayakam and the Federal Party painstakingly explained that they were by no means opposed to Sinhalese voluntarily living in Tamil areas, either as a matter of choice, pursuing business or as government and private sector employees, but the nuancing was quite easily lost in the political shouting match.

The fourth demand, after citizenship, regional autonomy, and land, was about language. Language was not an issue when Chelvanayakam started the Federal Party. But he pessimistically predicted that sooner or later the then prevailing consensus, based on a State Council resolution, over equality between the two languages would be broken. He was proved right, sooner than later, and language became the explosive question in the 1956 election. As it turned out, the UNP government was thrown out, SWRD Bandaranaike led a coalition of parties to victory and government in the south, while SJV Chelvanayakam won a majority of the seats in the North and East, including two Muslims from Kalmunai and Pottuvil.

After the passage of the Sinhala Only Act on June 5, 1956, the Federal Party launched a political pilgrimage and mobilized a convention that was held in Trincomalee in the month of August. The four basic demands were concretized at the convention, viz., citizenship restoration for the hill country Tamils, parity of status for the Sinhala and Tamil languages, the cessation of state sponsored land colonization, and a system of regional autonomy in the Northern and Eastern Provinces.

The four demands became the basis for the Bandaranaike-Chelvanayakam agreement – the B-C Pact of 1957, and again the agreement between SJV Chelvanayakam and Dudley Senanayake in 1965. The former was abrogated by Prime Minister Bandaranaike under political duress but was not abandoned by him. The latter has been implemented in fits and starts.

The two agreements which should have been constitutionally enshrined, were severely ignored in the making of the 1972 Constitution and the 1978 Constitution – with the latter learning nothing and forgetting everything that its predecessor had inadvertently precipitated. The political precipitation was the rise of Tamil separatism and its companion, Tamil political violence. Ironically, Tamil separatism and violence created the incentive to resolve what Chelvanayakam had formulated and non-violently pursued as the four basic demands of the Tamils.

After his death in 1977, the citizenship question has finally been resolved. The 13th Amendment to the 1978 Constitution that was enacted in 1987 resolved the language question both in law and to an appreciable measure in practice. The same amendment also brought about the system of provincial councils, substantially fulfilling the regional autonomy demand of SJV Chelvanayakam. The land question, however, has taken a different turn with state sponsored land colonisation in the east giving way to government security forces sequestering private residential properties of Tamil families in the north, especially in the Jaffna Peninsula.

Further, the future of the Provincial Council system has become uncertain with the extended postponement of provincial elections by four Presidents and their governments, including the current incumbents. The provinces are now being administered by the President through handpicked governors without the elected provincial councils as mandated by the constitution. Imagine a Sri Lanka where there is only an Executive President and no parliament – not even a nameboard one. “What horror!”, you would say. But that is the microcosmic reality today in the country’s nine provinces.

“AI increases profits while reducing un ethical intervention which is proven by Successful Global Business Models”

Artificial Intelligence(AI) is still only a buzz word in the Sri Lankan society, though many wanted to have an awareness of the concept the resources are scares, even still the IT industry has not formulated any awareness programs or a Degree yet to cope with the development. But world education warns that there want be any IT based jobs in future without learning the AI. AI has multiple use in any discipline and it has the ability to increase the efficiency of the work intern cut down the product or the service cost. Below description is how the application of AI can smoother the function of Logistic or the Supply Chain Management.

AI Integrating Procedure for Distribution Systems

Using Artificial Intelligence (AI) in logistics can greatly improve efficiency, reduce costs, and enhance decision-making in simple enhance the profit margins. Below is a structured overview of how AI can be used in logistics, including key applications, tools, and real-world examples. Machine Learning(ML) is the foundation to AI but subsequently develops the capability of absorbing the information from the cloud (IT environment) and produce future behavior or trends by analyzing the fed data to the computers on a certain period of time. In some occasions vendors offer unbelievable discounts by using ML or AI, because it clearly understands the market behavior, human behavior, expiration and many other variables that gives the profits or losses to the product or the service.

Key Areas Where AI is Used in Logistics;

· Demand Forecasting

· Route Optimization

· Warehouse Automation

· Predictive Maintenance

· Inventory Management

· Supply chain Management

· Customer Service with Chat bots

· Fraud Detection and Risk Management

1. Demand Forecasting

AI can analyze historical data, market trends, and external factors (like weather or news) to:

· Predict product demand more accurately

· Optimize inventory levels

· Reduce stockouts or overstocking

Tools: Machine learning models (e.g., time series forecasting) and IT platforms/software like Amazon Forecast, Prophet by Meta. These are the software applications that helps to understand the future trends.

Amazon Forecasting software

Traditional forecasting methods typically rely on statistical modeling, but software like “Chronos” that treats time series data (data collected during a certain period of time) as a language to be modeled and uses a pre-trained FM (forecast Models) to generate forecasts, which similar to how “Large Language Models” (LLMs) generate texts helps you achieve accurate predictions faster, significantly reducing development time compared to traditional methods.

Prophet by Meta

Prophet is a very efficient and accurate procedure for forecasting time series data based on an additive model where non-linear trends are fit with yearly, weekly, and daily seasonality, plus holiday effects. It works best with time series that have strong seasonal effects and several seasons of historical data. This software adds many social, cultural and geographical variables other than internal information to decision making.

2. Route Optimization

AI-powered systems can calculate the most efficient delivery routes in real-time using:

· Traffic data

· Weather conditions

· Delivery time windows

· Vehicle capacity and fuel usage

Example: UPS (one of the largest Logistic companies in the world) uses its ORION system (AI-based) to save millions of gallons of fuel per year.

IT Tools: Google OR-Tools, Route4Me, Mapbox with ML integration.

IBM Maximo is a multi-facet coordinator

The “Route4Me” IT platform automates and integrates mission-critical last mile workflows, empowering route planners, dispatchers, drivers, and managers to take the business to the next level. Distribution networks, passenger transportation networks can achieve much cost reduction by using above platforms. This is a good platform for the Sri Lanka passenger industry to reduce the overheads for the population. In Sri Lanka “Pick me” and “Uber” uses similar platforms in their transportation industry. Whole three wheeler industry can be regulating with this kind of software and transfer benefits to the passengers.

3. Warehouse Automation

AI enables:

· Robotics for picking, packing, and sorting

· Vision systems for scanning and inventory management

· Autonomous forklifts and drones for internal transport

Example: Amazon’s use of “Kiva robots” in fulfillment(distribution) centers.

Kiva Robots in Warehouses

Traditionally, goods are moved around a distribution center using a conveyor system  or by human-operated machines (such as forklifts). In Kiva’s approach, items are stored in portable storage units. When an order is entered into the Kiva database system, the software locates the closest automated guided vehicle to the item and directs it to retrieve it. The mobile robots navigate around the warehouse by following a series of computerized bar-code stickers on the floor. Each drive unit has a sensor that prevents it from colliding with others. When the drive unit reaches the target location, it slides underneath the pod(Pallet) and lifts it off the ground through a corkscrew action. The robot then carries the pod to the specified human operator to pick up the items or subsequently hand over to the “drone” to deliver to the customer. Human intervention is minimal and accordingly overheads are reduced, Sri Lanka needs to achieve this kind of operational level in order to par with the international markets.

4. Predictive Maintenance

Traditionally Sri Lankans are week in maintenance, they basically wait until the machine stops in the other way bureaucratic too are much restrict on the maintenance and the procurement procedure. Applying this kind of maintenance software will eradicate all of these lethargies and the bureaucratic blocks. Subsequently continuing the smooth operations and productions.

AI monitors equipment (vehicles, conveyor belts, etc.) to:

· Predict when they will fail

· Schedule maintenance proactively

· Reduce downtime and repair costs

Tools: IoT(internet of things as cameras, sensors, GPS etc.) sensors + ML models (e.g., anomaly detection), IT platforms like IBM Maximo.

IBM Maximo is a multi-facet coordinator

“From equipment to factories, from fleets to infrastructure, Maximo Application Suite empowers users across verticals to coordinate maintenance and management for a broad range of asset classes”.

5. Supply Chain Visibility

AI can analyze data across the supply chain to:

· Track shipments in real-time

· Identify delays or bottlenecks

· Provide predictive ETAs

📦 Example: DHL (Logistic Company) uses AI to forecast transit delays and offer dynamic ETA updates.

This is an ideal tool for cargo management, ideal for sea ports and the air ports in Sri Lanka. This is one of the grave gray areas in the port system, though the port system is lacking the required information due to that the client has to pay the demurrages and warehouse cost for the ports. Also, cut down unnecessary delays and reduce bribes and corruption at all levels.

6. Inventory Management

AI helps optimize:

· Stock levels across multiple warehouses

· Replenishment timing

· Safety stock calculation

Tools: ERP (Entrepreneur Resource Planning) systems with embedded AI (e.g., SAP, Oracle), custom ML models.

These systems drastically reduce the human intervention and speedup the Supply management process.

7. Customer Service & Chatbots

AI-powered chatbots and virtual assistants can:

· Handle customer queries 24/7

· Track orders

· Provide personalized delivery updates

Tools: Dialogflow, Microsoft Bot Framework, ChatGPT API

Dialogflow

“Dialogflow” is a natural language understanding IT platform that makes it easy to design and integrate a conversational user interface into the mobile app, web application, device, bot, interactive voice response system, and so on. Using Dialogflow, establishments can provide new and engaging ways for users to interact with the product. Dialogflow can analyze multiple types of input from the customers, including text or audio inputs (like from a phone or voice recording). It can also respond to the customers in a couple of ways, either through text or with synthetic speech.

AI Conversational Chatbots Platform

Above IT platforms control the human intervention and reduce the cost of employees. Chatbots are basically efficient than the humans due to the high memory power for the standard customer inquiries. Application to Government sector will reduce the burden for the general public.

8. Fraud Detection & Risk Management

AI detects unusual patterns in:

· Orders

· Transactions

· Supplier behavior

Helps prevent:

· Cargo theft

· Counterfeit goods

· Financial fraud

*”KPMG Clara” for Supply Chain Risk Management

“KPMG Clara” is an AI-powered IT platform offering supply chain analytics, risk detection, and compliance management.

Key Features:

· AI-driven risk modeling

· ESG (Environmental, Social and Governance) and compliance monitoring

· Predictive analytics for disruptions

· Supplier risk scoring

“Geo Analysis” (AI based) IT platform in Supply Chain Access Control

Above IT platform Monitor access patterns across cross-border freight hubs, regional warehouses, and remote carrier logins. “Geo analysis” for supply chain authentication identifies impossible travel, geo-inconsistencies, and spoofed IPs to reduce credential abuse and unauthorized entry into logistics systems. This important IT platform can reduce corruption and many unethical practices, ideal tool for the Sri Lankan Government sector that can curb the mal practices.

Artificial Intelligence (AI) is a remarkable IT tool which can apply in almost all the sectors that can reap the Efficiency and Accuracy. In above paragraphs I have described the application in different stages of the Logistic or the Supply Chain Management. Application of AI tools can be done on stages as initially find the specific pain points pertaining to the supply chain and then, prepare data from the GPS, inventory systems, sales forecasts and supplier records. Subsequently can understand the specific AI platforms and ML models to suit the SCM operation. Further, can apply in a small scale as a pilot project and analyze impact as cost savings or efficiency gains. Once understand the model can roll out to other areas of operations in the establishment.

Final outcome will be “15% reduction in fuel cost, 20% faster deliveries, Increased customer satisfaction”

There may be many negative lobbies since this is new to the many sectors in the country and further ability to proof the corruption but proper education and understanding the world AI based business models, establishments can reach the required goal.

Motherhood is not ‘giving up’

Published

on

Since having my baby, I have been regularly met with the question, “Are you back at work?”

“No,”

I reply. “I am doing my PhD from home.”

Several emotions arise. I feel guilty that I am not back at work, that somehow I should be. I also feel relieved that I can justify my time at home by offering up the PhD as a worthy endeavour. Sometimes, the person responds in surprise, “Oh, so no work?” Other times, they are approving, “How lucky for you and your baby.” Occasionally, there is the advice, “Don’t give up work.”

At the back of my mind are certain thoughts. “Am I not ‘working’? Isn’t the work of motherhood also considered ‘work’? If it isn’t, shouldn’t it be?”

Although the questions, comments, and advice about returning to work are made innocently enough, mostly benevolently, they have prompted me to reflect on the idea of work and motherhood, and how mothers and society view both.

Motherhood, I believe, is a full-time, highly skilled, unpaid job that never ends. All mothers work at least two jobs. They do the work of mothering, and also work in either a paid or unpaid additional role. Many women will do even more. They mother, care for their elderly parents, work a paid job, voluntarily contribute to community building, and try to fit in creative pursuits, hobbies, or ‘self-care’ when they can.

Motherhood requires many skills. You are, effectively, the CEO of your family and home (with hopefully a supportive co-CEO by your side). There is the work of child-rearing, which requires patience, energy, creativity, presence, flexibility, courage, fortitude, knowledge, and the ability to research, learn, and unlearn. You are raising the future. Then there is the work of home and family life, which requires skills in leadership, organisation, prioritisation, delegation, negotiation, financial management, crisis management, and conflict resolution. There is also the internal work of being self-aware, forgiving yourself and others, practicing compassion, and accepting the inherent imperfections of ‘doing it all’.

This work of motherhood is now recognised as ‘unpaid caregiving and domestic work’ and ‘invisible labour’ by international organisations such as the United Nations. It includes physical labour, direct care labour, mental or cognitive labour, and emotional labour, and is mostly the work of women.

I am not complaining. Men have their own unpaid labour. I love being a mother and wife. I view it as a privilege and a blessing. Ideally, the job can also be supported by paid or unpaid help. My point is that the work of women, and specifically mothers, should be recognised and respected, not only by society, but also by women and mothers themselves.

I know it is not just me who has experienced conflicting emotions about ‘giving up’ traditional work to focus on family life. Within my social circle and more widely, mothers describe a loss of self-worth and identity unless they are ‘working mothers’, and feeling embarrassment and guilt when asked the dreaded question, “What do you do?” There is the loss of financial dignity that comes with taking on an unpaid job, no matter how important you may think it is. Dynamics with husbands also need to shift, where both members are viewed as equally valuable to making the business of ‘home’ successful.

Neha Ruch, the author of The Power Pause, is an American brand strategist-turned-full-time stay-at-home mother and home maker, who addresses this very issue. Many of my thoughts for this article are based on her book. She argues that the time a woman wishes to invest in this phase of life, motherhood and family life, is valuable, not just for the children or family unit, but for the mother herself. It is a time for growth, skill-building, and expanding networks and connections.

Often, it leads women in new, creative, and more fulfilling directions, and provides an opportunity for them to re-enter the workforce on their own terms. She also points out that ‘the pause’ is not a luxury for a lucky minority, as many women become the default caregiver for their children if childcare is too costly, or not the preferred option. Through the movement she has created, Ruch provides legitimacy, validation, and structure to this phase of life (because, after all, it is only a phase, not forever) that is often spoken of as mindless, monotonous, and unglamorous, and I am grateful for it.

I suppose what I am saying is, next time you meet a mother, consider asking her, “How are you?”, and next time I am asked what I do, I should proudly declare (using Ruch’s script), “Right now, I am on a career pause and get to be home with my baby, and I am exploring possibilities for the future.”
