Shopping Activity At Warehouse Club Stores And Its Competitive And Network-Density Implications, Stanley Frederick W.T. Lim, Elliot Rabinovich, Sungho Park, Minha Hwang Jun 2020

Shopping Activity At Warehouse Club Stores And Its Competitive And Network-Density Implications, Stanley Frederick W.T. Lim, Elliot Rabinovich, Sungho Park, Minha Hwang

School of Business: Faculty Scholarship

Warehouse club (WC) retailers have typically expanded to new markets using stand‐alone stores, rather than pursuing dense store networks as other (non‐WC) retailers have in the past. While this strategy generates operating efficiencies, it also imposes high travel costs on households to shop, which calls into question WC stores’ resilience to spatial competition from stores operating other formats. We examine this phenomenon by using data on households’ shopping activity across markets served by Costco Wholesale stores. Specifically, we evaluate these stores’ resilience to spatial competition by estimating the share of households’ expenditures relative to travel costs to shop at the …

Flexibly Serving A Finite Number Of Heterogeneous Jobs In A Tandem System, Yun Fong Lim, Bingnan Lu, Rowan Wang, Wenjia Zhang

Research Collection Lee Kong Chian School Of Business

Many manufacturing and service systems require a finite number of heterogeneous jobs to be processed by two stations in tandem. Each station serves at most one job at a time and there is a finite buffer between the two stations. We consider two flexible servers that are cross-trained to work at both stations. The duration for a server to finish a job at a station is exponentially distributed with a rate that depends on the server, the station, and the job. Our goal is to identify an efficient policy to dynamically assign the servers to the stations such that the …


Integrating Anticipative Replenishment-Allocation With Reactive Fulfillment For Online Retailing Using Robust Optimization, Yun Fong Lim, Song Jiu, Marcus Ang Jun 2020

Integrating Anticipative Replenishment-Allocation With Reactive Fulfillment For Online Retailing Using Robust Optimization, Yun Fong Lim, Song Jiu, Marcus Ang

Research Collection Lee Kong Chian School Of Business

Problem definition: In each period of a planning horizon, an online retailer decides on how much to replenish each product and how to allocate its inventory to fulfillment centers (FCs) before demand is known. After the demand in the period is realized, the retailer decides on which FCs to fulfill it. It is crucial to optimize the replenishment, allocation, and fulfillment decisions jointly such that the expected total operating cost is minimized. The problem is challenging because the replenishment-allocation is done in an anticipative manner under a “push” strategy, but the fulfillment is executed in a reactive way under a …

The Dynamics And Effects Of Supply Network Structure, Marat Davletshin May 2020

The Dynamics And Effects Of Supply Network Structure, Marat Davletshin

Graduate Theses and Dissertations

The rising interest in network theory among supply chain scholars reflects an emerging shift in perspective. To deliver global speed, efficiency, and responsiveness, modern firms’ supply chains are becoming increasingly complex. The patterns of interactions and interdependencies among hundreds of firms interconnected by these complex supply chains cannot be adequately explored from the dyadic perspective, which has dominated supply chain research for decades. Many supply chain scholars agree that the language of networks can provide a syntax and structure to describe and explore this complex reality. The actual application of network theory in supply chain research, however, has been limited. …

Markets And Supply Chains: An Investigation Of The Institutions Influencing The Farm-Supply Chain Interface, Jessica L. Darby

Graduate Theses and Dissertations

Farm-level operations have lasting and amplified impacts that promulgate the entire supply chain, and the farm is increasingly in the forefront of today’s headlines on topics such as social responsibility, environmental sustainability, traceability, and food safety. Despite its significance, however, the farm remains a ‘black box’ and has traditionally operated independently with little information-sharing, trust, or collaboration with buyers downstream. This dissertation begins to unpack this ‘black box’ by employing different methodologies to identify the factors influencing exchange in the farm-supply chain interface. In Essay 1, I examine why the farm continues to be a challenge for ‘traditional’ collaborative approaches …
