The June 7, 2021 ORSP webinar on the topic Logistics in Challenging Times was very well attended with 227 members and students from various schools. The talks of the two invited speakers complemented each other to give a picture of what is happening in the Logistics area in the Philippines and around the world.
Gloria T. Estabaya of San Miguel Integrated Logistics Services, Inc. presented trends in logistics that are disrupting the industry, namely: 1) technology which through analytics, GPS, autonomous vehicles, internet of things, and AI have enabled faster and reliable delivery of services; 2) the changing needs and wants of various market segments which is increasingly demanding, including a mix of millennial and affluent older customers; 3) macroeconomic trends of globalization, climate change, urbanization, etc; and 4) the current pandemic.
On the other hand, the Philippines is faced with challenges of 1) an archipelagic geography; 2) widely varying population densities; 3) internet infrastructure; and 4) the region’s highest logistics costs.
She emphasizes that logistics makes possible the advent of digital marketing, online shopping, as well as traditional shopping experience. She described how digitization in transportation and logistics makes it possible to optimize processes and capture real time information to enhance service delivery.
The second speaker, Patric Ellis Chua Uy, shared how his company, L & F Logistics, a regional third-party service provider, has embraced digitalization to transform the different elements of the supply chain into data that could provide valuable insights. This is key in equipping the company with speed to make decisions faster, operate with agility and innovative ways of doing business.
This is made possible through the use of off-the shelf tools that perform supply chain network optimization; supply chain mapping through GIS; market demand analysis and geo-processing; for statistical computing with Python and Minitab; transportation and shipment planning and optimization; data visualization, big data and business intelligence; warehouse layout and simulation; and lastly, vehicle routing and scheduling, along with fleet planning and management. The speaker gave examples on the use of these tools and how it has helped design a supply chain network in the Philippines; design an optimal SKU arrangement in warehouses through simulation; plan transport shipments that take into account time windows, vehicle types and service levels; and dispatch vehicles with real-time dashboards. He explained the importance of a Control Tower which enables monitoring of processes, KPIs and exceptions across the freight, warehousing and transport operations.
A lot of questions were asked by the audience. The recording of the lecture is available to attendees at https://youtu.be/AVQV782y7g4; https://youtu.be/mJ_Ix_KX4iY. The two hour session gave a full picture of the logistics challenges and how it is being addressed. Webinar participants, who rated the session at near perfect levels, benefited greatly from the cumulative and extensive logistics experience of the two speakers.

Value of Digitization in the Supply Chain and the Role of Logistics in Surviving Covid-19
Abstract
Logistics can make or break the promise of digital marketing, on line shopping and even the current brick and mortar shopping experience. Rising to the digitization challenge in transportation and logistics opens big opportunities in optimizing processes and capturing real time information to enhance transparency and increase customer orders. In the current environment, where less people go out to buy their needs and more people do on line shopping due to the hassles of COVID19 scare and health protocols, logistics thrives to co-exist with the virus.

The International Federation of Operational Research Societies (IFORS) to which the ORSP belongs announced the launching of the IFORS Fellows Award last January 15, 2021. Elise del Rosario of ORSP was included in the first set of awardees. According to the award letter issued by IFORS President Grazia Speranza, the award is a recognition of her “dedicated efforts over the years to help IFORS promote the development of OR worldwide, both in methodology and practice and to link member societies together.
Del Rosario joins 19 others (https://www.ifors.org/ifors-fellows/) in the list of which she is the only woman and Asian. She was IFORS President from 2007 to 2009. She is one of the founding Presidents of ORSP, at the time that she was head of the Operations Research Group of San Miguel Corporation, from where she retired at its Vice President. It will be recalled that the San Miguel Corporation was awarded the 1992 Operations Research Society of America Prize for its sustained and consistent use of OR in organizational decision-making.
Founded in 1955, IFORS is the only global organization in the field of OR and counts some 54 OR national societies with over 30,000 individual members. E. del Rosario is a graduate of BS Industrial Engineering from UP Diliman, Master of Engineering in Industrial Engineering and Management from the Asian Institute of Technology and was an International Fellow at the Stanford Research Institute.
First Quarterly ORSP Forum Shows OR Approaches in Responding to the Pandemic
ORSP launched its first quarterly online technical forum for 2021 with its first in the series on the theme OR: Helping Respond to the Pandemic.
The two-hour forum was opened by ORSP Executive Director Elise del Rosario who introduced ORSP President Marie Shella Mariscal, Operations Research Manager of the San Miguel Corporation. Her welcome remarks highlighted how the Covid 19 has impacted all aspects of life and the economy and the relevance of OR in all these experiences, as will be shown in the two talks for the day.
ORSP Board member Dennis Cruz introduced Dr. Charlle Sy who is an associate professor and research fellow in the Department of Industrial Engineering of De La Salle University. She in turn, introduced co-presenter Dr. Dr John Frederick Tapia who is an associate professor in the Department of Chemical Engineering of De La Salle University.
Their paper on An Optimization Approach to the Allocation of Covid-19 Vaccines tries to address how to allocate a limited amount of vaccines specially in the initial roll out that will minimize reinfection rates. She discussed how initially, an LP model to do this was developed that minimizes the sum of fatality rates among the various age groups. The output, however, showed that reinfection rates did not improve appreciably with this approach. They developed a second model that minimizes reinfection rates with the use of eigenvalues. This resulted in a nonlinear programming model which minimizes the reproduction rate of the virus. The reproduction rate represents the expected number of secondary infections generated by an infectious individual. As designed, the model could handle multiple vaccines with different levels of efficacy. A hypothetical case study illustrates the computational capability of the model. Furthermore, the group of Dr. Tapia has developed a Python-based software to aid in model deployment.
The series of questions posed by the audience moderated by D. Cruz showed the high level of audience interest in the research and suggestions on possible improvements with the use of actual data were mentioned.
The second speaker was introduced by ORSP Board member Nestley Sore – Vic Reventar is himself an ORSP Board member and a Lecturer at the Department of Quantitative Methods and Information Technology Department at the John Gokongwei School of Management at the Ateneo de Manila University who has done extensive consulting work in various areas of Operations Research, one of which concerns his talk, the COVID 19 and its Effects on Supply Chains in the Philippines.
The immediate Philippine government measure to mitigate the pandemic, Enhanced Community Quarantine (ECQ), limited the mobility of people and minimized “contact-rate” through social distancing. These resulted not only in income reduction for most employees but also unintended effects on the manufacturing and agricultural sectors and their distribution systems. These consequences were fully visualized in the system dynamics and agent-based modeling simulation models of the Covid 19 and supply chain presented by the speaker.
V. Reventar pointed out that the model clearly illustrates that systems are interlinked and that policy decisions affect a major segment of society. This kind of analysis will be useful in evaluating the most effective way of addressing disruptions in the local supply chains which include such measures as increasing production and inventory capacities, repositioning inventories in certain regions or facilities under quarantine, and others. He pointed out that any disruption affecting any segment in the supply chain affects the integrity of the whole chain and the time-to-recover from such a disruption.
He ended by recommending that the government policy effort in managing the effects of COVID-19 must consider the flow of goods and services with the use of the simulation models presented. Again, the questions at the end acknowledged the power that this modeling could potentially offer to the current situation.
It could be said that the136 participants from UST, UP Los Baños, Holy Angel University, De La Salle Lipa, Quezon City Polytechnic University, Batangas State University – Alangilan, Asia Pacific College, Adamson University, San Miguel Corporation, Phil Batteries Inc., and CSIRO (Australia) left the zoom meeting with an added perspective of how OR tools could aid national policy.

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.

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.

The International Federation of Operational Research Societies (IFORS) to which the ORSP belongs announced the launching of the IFORS Fellows Award last January 15, 2021. Elise del Rosario of ORSP was included in the first set of awardees. According to the award letter issued by IFORS President Grazia Speranza, the award is a recognition of her “dedicated efforts over the years to help IFORS promote the development of OR worldwide, both in methodology and practice and to link member societies together. 
Their paper on An Optimization Approach to the Allocation of Covid-19 Vaccines tries to address how to allocate a limited amount of vaccines specially in the initial roll out that will minimize reinfection rates. She discussed how initially, an LP model to do this was developed that minimizes the sum of fatality rates among the various age groups. The output, however, showed that reinfection rates did not improve appreciably with this approach. They developed a second model that minimizes reinfection rates with the use of eigenvalues. This resulted in a nonlinear programming model which minimizes the reproduction rate of the virus. The reproduction rate represents the expected number of secondary infections generated by an infectious individual. As designed, the model could handle multiple vaccines with different levels of efficacy. A hypothetical case study illustrates the computational capability of the model. Furthermore, the group of Dr. Tapia has developed a Python-based software to aid in model deployment.
The series of questions posed by the audience moderated by D. Cruz showed the high level of audience interest in the research and suggestions on possible improvements with the use of actual data were mentioned.
The second speaker was introduced by ORSP Board member Nestley Sore – Vic Reventar is himself an ORSP Board member and a Lecturer at the Department of Quantitative Methods and Information Technology Department at the John Gokongwei School of Management at the Ateneo de Manila University who has done extensive consulting work in various areas of Operations Research, one of which concerns his talk, the COVID 19 and its Effects on Supply Chains in the Philippines.
The immediate Philippine government measure to mitigate the pandemic, Enhanced Community Quarantine (ECQ), limited the mobility of people and minimized “contact-rate” through social distancing. These resulted not only in income reduction for most employees but also unintended effects on the manufacturing and agricultural sectors and their distribution systems. These consequences were fully visualized in the system dynamics and agent-based modeling simulation models of the Covid 19 and supply chain presented by the speaker.
