Distributional equity is a particularly salient objective in public sector decision making, in general, and decision making concerning the delivery of public services such as education, libraries, sanitation, and public safety, in particular. In this paper two related bicriteria mathematical...

This paper studies the problem of scheduling jobs on parallel machines with setup times. When a machine switches from processing one type of job to another type, setup times are incurred. The problem is to find a feasible schedule for each machine which maximizes the total reward. We study three...

We present an application of mathematical programming for solving a complex multi-level production and distribution network optimization problem faced by a petrochemical company. Two liquified petroleum gas (LPG) products, propane and butane, are produced at refineries, from where they are...

The problem of determining consistent and realistic reorder intervals in complex production-distribution environments was formulated as a large scale, nonlinear, integer programming problem by Maxwell and Muckstadt (Maxwell, W. L., J. A. Muckstadt. 1985. Establishing consistent and realistic...

Technological advances in both the manufacturing and office sectors have emphasized the need to link processors and communications equipment into Local Area Networks (LANs) to facilitate communication and promote resource sharing. Interviews with designers and users of LANs revealed that a...

This note establishes a class of best possible upper bounds for the Dynamic Plant Layout Problem (DPLP) examined by Rosenblatt (Rosenblatt, M. J. 1986. The dynamics of plant layout. Management Sci. 32 76--86.) in this journal. We use the notation of that paper.

Econometric and dynamic programming analysis is used to derive optimal operating rules for water resources used in electricity generation. The methodology is applied to an actual mixed power system with interconnected thermal and hydro plants. Results obtained are compared with the electricity...

In this paper we develop a resource planning and allocation model for a mental-health community-support system. The intent of the model is to provide a tool to system managers and planners to support resource planning and allocation decision-making. More and more, mental health care is being...

The problem of plant layout has generally been treated as a static one. In this paper, we deal with the dynamic nature of this problem. Both optimal and heuristic procedures are developed for this problem and are based on a dynamic programming formulation. The use of one of these approaches...

We develop an optimization procedure for assisting decision-makers in the allocation of resources for cleaning up a specific oil spill. The objective function is to minimize a weighted combination of spill-specific response and damage costs. Inputs to this problem include information about the...
