摘要：Efficient inventory management in the face of product variety is an important part of retail operations management. In this study, we analyze the optimal stocking policy for a retailer, in a setup with a single horizontally differentiated product with an arbitrary number of product variants, stochastic demand, and two-level consumer choice. The demands for individual product variants are negatively correlated conditional on the total demand. We assume that each customer will purchase one unit ...

摘要：In this study, we employ system dynamics to study the combined effect of extended payment terms and a buyer's supply risk management practices on two outcomes: the supplier's bankruptcy risk and the buyer's financial bottom line. In conjunction with payment terms, we model the impact of two commonly recommended supply chain risk management (SCRM) practices: quick response to supply disruptions and use of a secondary (backup) source. Among other results, we uncover a feedback mechanism that con...

摘要：The new sharing economy model has introduced a dramatic, disruptive impact on the traditional industries by matching the demand and supply in real time. In this study, we examine how the entry of Uber, a ride-sharing services digital platform, brings new disruptive changes in public transportation operations. Significant debate has surrounded whether the new ride-sharing model siphoned riders from public transit or made public transit feasible for more riders, but no consensus has been reached...

摘要：In this work, we study the assortment planning games in which multiple retailers interact in the market. Each retailer owns some of the products and their goal is to select a subset of products, that is, an assortment to offer to the customers so as to maximize their expected revenue. The purchase behavior of the customer is assumed to follow the Markov chain choice model. We consider two types of assortment games under the Markov chain choice model-a competitive game and a cooperative game. I...

摘要：Product proliferation occurs in supply chains when manufacturers respond to diverse market needs by trying to produce a range of products from a limited variety of raw materials. In such a setting, delaying the point of the proliferation helps manufacturers improve their responsiveness by postponing the ordering decisions of the final products until there is partial or full resolution of the demand uncertainty. This strategy can be implemented in two different ways: (i) redesigning the operati...

摘要：This study is motivated by the challenges faced by clinics in sub-Saharan Africa in allocating scarce and unreliable supply of antiretroviral drugs (ARVs) among a large pool of eligible patients. Existing discussion of ARV allocation is focused on qualitative rules for prioritizing certain socioeconomic and demographic patient segments over others at the national level. However, such prioritization rules are of limited utility in providing quantitative guidance on scaling up of treatment progr...
