Analyzing Country-Level Vaccination Rates and Determinants of Practical Capacity to Administer COVID-19 Vaccines
Sharika J. Hegde, Max T. M. Ng, Marcos Rios +3
The COVID-19 vaccine development, manufacturing, transportation, and administration proved an extreme logistics operation of global magnitude. Global vaccination levels, however, r…
Inferring sources of substandard and falsified products in pharmaceutical supply chains
Eugene Wickett, Matthew Plumlee, Karen Smilowitz +2
Substandard and falsified pharmaceuticals, prevalent in low- and middle-income countries, substantially increase levels of morbidity, mortality and drug resistance. Regulatory agen…
Generalizing the Covering Path Problem on a Grid
Liwei Zeng, Karen Smilowitz, Sunil Chopra
We study the covering path problem on a grid of R^{2}. We generalize earlier results on a rectangular grid and prove that the covering path cost can be bounded by the area and peri…
Incorporating Equity into the School Bus Scheduling Problem
Dipayan Banerjee, Karen Smilowitz
We consider the school bus scheduling problem (SBSP) which simultaneously determines school bell times and route schedules. Often, the goal of the SBSP is to minimize the number of…
A Bounded Formulation for The School Bus Scheduling Problem
Liwei Zeng, Sunil Chopra, Karen Smilowitz
This paper proposes a new formulation for the school bus scheduling problem (SBSP) which optimizes school start times and bus operation times to minimize transportation cost. Our g…
The Covering Path Problem on a Grid
Liwei Zeng, Sunil Chopra, Karen Smilowitz
This paper introduces the covering path problem on a grid (CPPG) which finds the cost-minimizing path connecting a subset of points in a grid such that each point that needs to be…
