Reducing manufacturing lead times and minimizing work-in-process (WIP) inventories are the cornerstones of popular manufacturing strategies such as Lean, Quick Response, and Just-in-Time Manufacturing. In this paper, we present a model that captures the relationshipbetween facility layout and...

Since procedures for producing optimal solutions to a quadratic assignment problem are computationally infeasible for any but small problems, heuristic techniques for producing approximate solutions must be employed for the solution of real practical problems. This paper presents the results of...

We consider a finite-horizon, multiechelon inventory system in which the surplus of stock can be sold (i.e., disposed) in the secondary markets at each stage in the system. What are called <i>nested echelon order-up-to policies</i> are shown to be optimal for jointly managing inventory replenishments...

In many industries, managers face the problem of selling a given stock of items by a deadline. We investigate the problem of dynamically pricing such inventories when demand is price sensitive and stochastic and the firm's objective is to maximize expected revenues. Examples that fit this...

The rapid growth of telecommunication capacity, driven in part by the wide-ranging deployment of fiber-optic technology has led to increasing concern regarding the survivability of such networks. In communication networks, survivability is usually defined as the percentage of total traffic...

We propose and analyze a heuristic that uses region partitioning and an aggregation scheme for customer attributes (load size, time windows, etc.) to create a finite number of customer types. A math program is solved based on these aggregated customer types to generate a feasible solution to the...

The proportionate flowshop is a special class of flowshops in which the operation times of jobs are proportionate, e.g., because of differences in the speeds of machines. In this paper, we make use of a special property of proportionate flowshops, namely that the bottleneck in the shop is almost...

Individuals often use several different strategies such as the expected value rule, conjunctive rule, and elimination-by-aspects, to make decisions. It has been hypothesized that strategy selection is, in part, a function of (1) the ability of a strategy to produce an accurate response and (2)...
