SPEAKERS:

Charlle Sy An Optimization Approach to the Allocation of Covid-19 Vaccines  Abstract: The global scientific community has been successful in their efforts to develop, test, and commercialize vaccines for COVID-19. However, the limited supply of these vaccines remains to be an overarching problem as different nations have started their respective vaccine rollouts. Policymakers continue to deal with the difficult task of determining how to allocate them. This talk will present how the use of mathematical models can provide valuable decision support under such conditions. A nonlinear programming (NLP) model has been developed to determine the optimal allocation of COVID-19 vaccines that minimizes the reproduction rate of the virus. The reproduction rate represents the expected number of secondary infections generated by an infectious individual. The model is capable of handling multiple vaccines with different levels of efficacy. Consequently, the distribution of vaccines reduces transmission and relative infectiousness of individuals across different age groups. A hypothetical case study is solved to illustrate the computational capability of the model, which can generate an allocation plan with outcomes that are superior to simple ad hoc allocation. Furthermore, a user interface has also been developed to aid in the deployment of the model. About the speaker: Charlle Sy is an associate professor and research fellow in the Department of Industrial Engineering of De La Salle University. She earned her B.S. and M.S. in Industrial Engineering from the same university. Meanwhile, she obtained her PhD in Industrial and Systems Engineering from the National University of Singapore. Her research interests are on robust optimization, systems thinking, and their applications to energy networks, supply chains, and environment systems.

Vicente Reventar COVID 19 and its Effects on Supply Chains in the Philippines Abstract: The Philippines has learned to be resilient in times of disasters (typhoons, massive floods, even earthquakes, and volcano eruptions) but nothing prepared the country for the effects of this COVID-19 global pandemic. Most disasters involve disruptions, and in the case of local typhoons and massive floods, we have at least 2-5 days lead-time to prepare since most given a global weather tracking system that monitors weather disturbances in real-time. Forecasting has been very accurate with the infrastructure set up by PAGASA to provide possible trajectories of the typhoons giving disaster agencies (including local government units and the DSWD reliant on local producers and their supply chains for relief goods) sufficient time to prepare for a quick response via pre-positioning of relief items. This pandemic caught everyone by surprise. The national government never took the threat seriously until infected cases began showing its dangerous “exponential” growth. Although we have disaster management agencies, there are geared toward a different type of disaster, not for a possible widespread health-bound disaster. Because of COVID-19, the immediate reaction of the Philippine government was to implement an Enhanced Community Quarantine (ECQ) designed to limit the mobility of people by restricting them through a “stay-at-home” directive and thus minimizing the “contact-rate” of people through social distancing. These 2 directives were aimed at “flattening” the exponential curve till newly infected people daily decreased progressively to acceptable levels. These policy directives which are still in effect right now had several “unintended consequences.” Private and government agencies are forced to shut down except for a very few exceptions. This resulted in the impairment of incomes for most employees. The shutdown also affected the manufacturing and the agricultural sector and its distribution systems. Most of our supplies today are current inventories of goods before the declaration of the ECQ. One could only speculate how long these inventories will last. Most local companies have designed a “lean” and JIT (just-in-time) supply chain to minimize the handling and carrying cost of inventories. Although suppliers may still have inventories and “safety stocks” the local logistic companies are having a difficult time in moving the finished goods and raw materials because of strict protocols in the checkpoints all around Luzon and the other areas in the Philippines. We also have to contend with perishable goods like vegetables and seafood that have limited shelf life even with refrigeration. This talk discusses several simulation models (COVID-19 models, supply chain models, both using system dynamics and agent-based modeling). These models try to “approximate” reality but in the end, the basic insight and “take away” is that all these systems are interlinked, and we should recognize these “tightly-coupled” interdependencies whenever we make policy decisions that could affect a major segment of society. An example of this policy decision is the government policy which imposed the ECQ, the government will probably decide at some point to lift (partially?) the restrictions allowing the flow of goods and services, and for employees in critical sectors (health, manufacturing, agricultural and transport sectors) to go back to work. The objectives are the replenishment of critical inventories and creating money flow in the system to provide relief to consumers wanting to buy basic goods. We all know that lifting the ECQ on the other hand, does come with a risk that the infection rates might go up again, putting the general population at peril. This may really qualify as a “vicious” problem. What can we do today and in the future to “immunize” our local supply chains in cases of partial disruptions? Most supply chain experts recommend reconfiguring the current supply chains by increasing production and inventory capacities. Other recommendations also include repositioning some inventories in certain regions or facilities under quarantine. Any segment in the supply chain (plant, distributor, wholesaler, retailer, “last-mile” -customer) will be subjected to disruptions affecting the integrity of the whole chain. The critical issue is the ability of individual “segments” time-to-recover when a disruption occurs. Ensuring a “fast” time-to recover will go a long way in ensuring the performance of the supply chain. Two supply chain organizations namely the Supply Chain Management Association of the Philippines (SCMAP) and, Philippine Institute of Supply Management. It is recommended that they be part of any government policy effort in managing the effects of COVID-19 in the flow of goods and services. About the speaker: Vicente Reventar is currently Lecturer at the Department of Quantitative Methods and Information Technology Department at the John Gokongwei School of Management at the Ateneo de Manila University. A current Board Member and former ORSP President, he served as President of SVI Technologies, Sr. Vice President of the Home Development Mutual Fund, Project Director of the Technology Resource Center of the Development Academy of the Philippines. He has done extensive consulting work in various areas of Operations Research.

Organized for APORS by the Operations Research Society of the Philippines (ORSP)

Date: September 23 – 25, 2020

 

INVITATION

Operations Research (OR) was born with the challenges brought by World War II. It has since its founding, addressed various business, economic, health, development and sustainability issues. As the world now faces the coronavirus pandemic, said to be the most challenging crisis the world has faced since the Second World War, OR continues to be a remarkable tool to help decision makers. With the theme OR: Continuing Relevance in Challenging Times, this online conference seeks to bring together OR researchers, academicians and practitioners, whose collective work has sustained continuing OR contribution to decision-making in the past and now, in the new normal.

The 2020 pre-APORS Conference aims to provide an online forum where:

• Practitioners will share their experiences on the problems, methodologies and outcomes of applying OR to solve real-world problems;
• Decision-makers will share new applications of OR in non-traditional areas;
• OR workers will discuss pertinent academic-, theoretical- and application- oriented issues;
• Decision-makers could gain insights from experiences of others who have benefited from the use of OR in the public and private sectors; and
• Everyone will be given the opportunity to exchange ideas on how OR can help deal with the current pressing issues.

Why call it a pre-APORS Conference?
The Association of Asia Pacific Operations Research Societies (APORS) is a regional grouping of the International Federation of Operational Research Societies (IFORS). Because of the current pandemic, the APORS conference slated for November 2021 has been moved to 2022 to make way for the postponed IFORS conference that should have been held in July, 2020.

Participants Learn about Machine Learning

The Workshop on Machine Learning using Python held from June 22 to 23 at the Mapua University attracted 31 participants. With the aim of introducing Machine Learning and introducing Python, the Workshop was successful in getting participants acquainted with the various applications of Python.

ORSP Past President Francis Miranda led the team consisting of Trixie de Guzman, Vanessa Bermudez and Danielle Hizola in guiding participants as they went through pre-worked Python code that covered 5 cases. Cases ranged from predicting: auto. Insurance levels, house prices, credit scores, survivors of a ship wreck, birth weight, and geographic clusters. This was preceded by an extensive introduction of real-life uses of machine learning.

Even as the introduction clarified that the two-day training is not a programming course, participants got an idea of the language syntax and worked their way through changing some codes to see the effects on the output.  Participants were exposed to a multitude of built-in Python libraries that they could call for their applications. As Board Director Rex Robielos quipped, “This will certainly fast track my learning of the language, which I had started taking up in Coursera.”  The workshop leaders cited the various resources to get participants started in serious programming. In cooperation with Cypher Learning, participants were provided access to all the materials – slides, programs, data sets – which they could use after the Workshop. 

Earlier, ORSP had also conducted a Workshop in R, and many participants acquainted with both commented on the advantages they see in shifting to Python. Other participants appreciated the opportunity to add to their set of Analytics tools. In general, participants gave the course and the trainers a score indicating satisfaction with the conduct of the Workshop and requested for additional training in other Analytics topics.

Participants came from: Cagayan State University, De la Salle – College of St Benilde, Holy Angel University, Mapua (Intramuros), Mapua University, Sunlife, Technopoly, Inc.  An annual offering of the ORSP, the Workshop this year was held in partnership with the Mapua University and Cypher Learning.

Participants included: Arman Loui Arquilada, Arian A. Rabino, Gina Tumang, Maria Elena Timbang, R-Jay Quiambao, Kimberly Hazel Serrano, Ruselle Andrew Manalang, Elmer Perez, Gerard Cortez, Flor Mangalino, Renilda S. Layno, Hardy D. Sierra, Ronald Arciaga, Raymond Sedilla, Gloren Fuentes, Joel De Goma, Josseline Nolasco, Marjorie Navales, Martha Lauren Tan.

**Registration is closed**

This technical forum aims to provide practitioners, teachers and students with developments in the applications of Operations Research and Analytics. The discussions by the accomplished speakers in various service industries will support the theoretical learning of OR/ Analytics in schools and enrich practitioners’ knowledge of applications in areas other than their current involvement. Specifically, the participants will learn from the experiences of practitioners in the food service, banking and finance, airlines and logistics sectors.
