We study how industry clockspeed, internal firm factors, such as product development, production, and inventory costs, and competitive factors determine a firm's optimal new-product introduction timing and product-quality decisions. We explicitly model market demand uncertainty, a firm's...

Manufacturers and their distributors must cope with an increased flow of returned products from their customers. The value of commercial product returns, which we define as products returned for any reason within 90 days of sale, now exceeds $100 billion annually in the United States. Although...

Who says a committee can't write a cogent report? Having reread the Guidelines and Appendix I (pp. 1127-1148) several times since publication, I am favorably impressed with the document's perspicacity. I make this statement not only to extend my compliments to the ORSA Ad Hoc Committee for a...

In this paper we study a model that minimizes the sum of production, employment smoothing, and inventory costs subject to a schedule of known demand requirements over a finite time horizon. The three instrumental variables are work force producing at regular-time, work force producing on...

This paper demonstrates the equivalence of several published algorithms for solving the so-called linear fractional programming problem.

Much research has been undertaken in the past several years on the uses of Leontief input-output matrices; applications have been made ranging from industrial growth models to models of interregional dynamics to estimates of structural changes in the economy. This paper discusses a general...

A forward algorithm for a solution to the following dynamic version of the economic lot size model is given: allowing the possibility of demands for a single item, inventory holding charges, and setup costs to vary over N periods, we desire a minimum total cost inventory management scheme which...

The (s, S) inventory model (infinite horizon with stationary parameters) is explored with a view toward determining the dependency of the optimal policy on the model's parameters and toward evaluating the effectiveness of several numerical approximation methods for obtaining nearly optimal...

Transportation models (ordinary and transhipment) having certain types of capacity constraints on the flows between origins and destinations are studied from the point of view of transforming them into enlarged standardized (non-capacitated) models. Specifically constraints on the flow from...
