Business organizations are faced with the financial and physical task of managing interrelated flows of material and cash. Material needs capital, and on the other hand, when finished goods are sold, they contribute to cash reserves. In this paper, we present and study a dynamic model in which...

We study lot-size policies in a serial, multi-stage, manufacturing/inventory system with two key generalizations, namely (1) random yields at each production stage and (2) an autoregressive demand process. Previous research shows that the optimal policies in models with random yields (even in...

This research is concerned with the development of an analytical framework for multiple and single source purchasing arrangements.

Coordination and control are critical aspects in the design of marketing channels due to the interdependence of various channel members and the complex flow of products, title to the products, payments and information. Important marketing decisions, such as prices and the level of promotional...

The proliferation of both online and bricks and mortar outlet stores underscores the observation that secondary markets are readily accessible to retailers of short-life-cycle products. These secondary markets provide recourse channels for retailers to sell excess inventory of out of favor items...

We define discrete time sequential games which are multiperson Markov decision processes. The extant theory is sketched and compared with our assessment of research needs in dynamic models of oligopoly and other competitive resource allocation problems. A special class of economic survival games...

We show that an easily computed and simply structured policy for making workorder decisions is optimal in the Clark-Scarf inventory model. That is a model of a make-to-stock multistage serial manufacturing process with convex costs of finished goods inventory, a set-up cost for purchasing,...

Manufacturers who outsource components incur risks as well as benefits. If the supplied product has a major quality defect, the adverse effect on the manufacturer's reputation reduces its market share. This paper presents a discrete-time model of a buyer who collaborates with a sole supplier to...
