This note develops optimal multiple rest break models for the case when the decay in work rate is an exponential function of time worked and recovery of work rate potential during rest is a linear function of time rested. While empirical evidence indicates that work rate decay functions tend to...

Municipal decision-makers face the difficult task of determining the amount of funds to be allocated for fire department services. This decision affects both the insurance class of the city and the total cost of fire protection. Total fire protection cost is the sum of the tax dollars spent for...

A multiobjective integer programming model is presented for allocating an area of land for development. The objectives considered in the allocation are cost, proximity to desirable and undesirable land features and the shape of the area. An interactive multiobjective optimization algorithm is...

Deciding which items to include in a sales catalog and how much space should be allocated to each item is a major planning problem facing many large retailers and catalog firms. The steps in the catalog planning process include compiling a list of candidate items, developing one or several ad...

Backup coverage, the second coverage of a demand node, is suggested as a decision criterion in modelling the location of emergency services on a network. The efficient handling of stochastic demand by vehicles which can respond to only one call at a time may require backup coverage in areas of...

This paper introduces a line of research on capacity-constrained multi-stage production scheduling problems. The first section introduces the problem area as it arises from a failure of MRP systems. Then a review of the literature and an analysis of the type of problems that exist are presented...

This paper is concerned with the problem of scheduling tasks on a system consisting of two parallel processors in order that makespan be minimized. In particular, we treat a variety of modifications to this basic theme, including the cases of identical, proportional, and unrelated processors. In...

A group decision process is developed that allocates an available budget to health programs based on program effectiveness. The program effectiveness is measured by comparing alternative programs (at various funding levels) with respect to the weighted objectives of the health care organization....

The problem of decreasing the amount of testing for vision loss in persons susceptible to glaucoma is formulated as an integer optimization problem. Nonlinear and linear versions of the problem formulation are given, and both heuristic and exact algorithms are proposed. Testing with...
