This paper studies a periodic-review, serial inventory system in which echelon (r, nQ,T) policies are implemented. Under such a policy, each stage reviews its inventory in every T period and orders according to an echelon (r,nQ) policy. Two types of fixed costs are considered: one is associated...

This thesis studies a single item periodic review inventory problem with stochastic demand, random price and quotation cost. It differs from the traditional inventory model in that at the beginning of each period, a decision is made whether to pay the quotation cost to get the price information....

Companies with high-performing supply chains enjoy essential competitive ad- vantages. However, supply chain management faces an environment of rising risk that endangers these competitive advantages. One of the reasons is to outsource parts of their business. This bears the risk of...

Operations of publicly traded firms differ from privately owned firms because public firms' managers make decisions based on their own interests. In this paper, we study how stock market pressure may influence a manager's inventory and operational management. Our model is a straightforward...

In this paper we first show that the gains achievable by integrating pricing and inventory control are usually small for classical demand functions. We then introduce reference price models and demonstrate that for this class of demand functions the benefits of integration with inventory control...

The ability to provide a cost-effective solution to improve hotel organizations efficiency through inventory management has made RFID technology one of today’s most potential deployment technologies. Hotel organizations are invariably competing in assuring the service quality and are facing...

W e develop a structural demand model that endogenously captures the effect of out-of-stocks on customer choice by simulating a time-varying set of available alternatives. Our estimation method uses store-level data on sales and partial information on product availability. Our model allows for...

The dissertation addresses optimization problems related to the management of product variety with inventory considerations. The objective is to provide insights and tools to help companies determine the optimal level of product variety they should produce/stock and maximize revenues by...

Uncertainty is a norm in business decisions. In this research, we focus on the inventory decisions for companies with uncertain customer demands. We first investigate forward buying strategies for single stage inventory decisions. The situation is common in commodity industry where prices often...

This dissertation consists of two distinct lines of research e orts. Chapter 2 proposes a general methodology to seek robust solution to multi-stage stochastic optimization problems. Chapters 3, 4 and 5 all deal with models that arise from inventory management and dynamic pricing. Chapter 2...
