Schedulers confronted with significant processing time uncertainty often discover that a schedule which is optimal with respect to a deterministic or stochastic scheduling model yields quite poor performance when evaluated relative to the actual processing times. In these environments, the...

Critical path models concerning project management (i.e. PERT/CPM) fail to account for work force behavioral effects on the expected project completion time. In this paper, we provide a modelling framework for project management activities, that ultimately accounts for expected worker behavior...

Although many authors have noted the importance of minimizing workflow interference in facility layout design, traditional layout research tends to focus on minimizing the distance-based transportation cost. This paper formalizes the concept of workflow interference from a facility layout...

In this paper, we study within a newsboy type modeling framework the common business practice of retail firms to sell products not only as independent items, but also as part of multiproduct packets (packaged goods). Our emphasis is on understanding the effects of such practices on the inventory...

A firm faces many problems that are inherently cross-functional. To solve them successfully requires the coordinated actions of many functional representatives acting in a decentralized setting. Functional managers, however, respond to their own individual incentives and may consequently fail to...

In this paper we address the discrete resource allocation problem in a deterministic flow line. We assume that the processing times are convex and nonincreasing in the amount of resources allocated to the machines. We consider the resource allocation problem for a fixed sequence of jobs for...

The global markets of today offer to the "style goods" producer more selling opportunities and pose new challenges in production planning and coordination. From a production management standpoint the opportunity to exploit the difference in timing of the selling season of geographically...

We study competitive marketplaces with multiple suppliers and multiple buyers dealing with a single product. A buyer chooses the supplier who offers the best price for his order profile, as described by his order size and delivery frequency. A supplier's offering price reflects her logistic cost...

We consider the impact of variable production costs on competitive behavior in a duopoly where manufacturers compete on quality and price in a two-stage game. In the pricing stage, we make no assumptions regarding these costs--other than that they are positive and increasing in quality--and no...

We study how differences in product demand characteristics affect the strategic value of different types of supply chain flexibility for accurate response. We propose a single-period inventory modelling framework with two ordering opportunities. The second order reflects updated demand...
