We consider some key features of capacity acquisition, disposal, and replacement decisions in this paper that are seldom captured in capacity expansion models in the literature. First, capacity is often purchased in the form of equipment which comes only in a few discrete sizes. Second, some or...

In this paper, we examine the nature of optimal inventory policies in a system where a retailer manages substitutable products. We first consider a system with two products 1 and 2 whose total demand is D and individual demands are negatively correlated. A fixed proportion of the unsatisfied...

While quality has attracted significant attention in the past two decades, the debate is still on as to whether a firm should aim for zero defects or base its quality decisions on cost-benefit trade-offs. The continuous improvement advocates generally eschew the cost trade-off approach, but U.S....

Numerous normative models have been developed to determine optimal inventory levels, and several articles and case studies have been written about the concerted efforts and practices adopted by manufacturing firms in the United States to reduce inventories. But little is known about whether...

In this paper, we study the standardization and customization decisions of two firms in a competitive setting, along with variety, lead time, and price decisions. We incorporate consumer heterogeneity both in firm preference (or store convenience) and in product attribute preferences. We find...

Manufacturers typically sell consumer products through retailers and the presence of intermediaries has interesting ramifications for their product variety and pricing decisions. Retailers may want higher variety to help reduce price competition but the costs of variety are borne by the...

This paper considers the deterministic capacity expansion problem with deterioration. First, the paper extends the conventional model by incorporating capacity deterioration effects and operating costs that are a function of: (i) the age of the facility and (ii) the extent of utilization of...
