A specially-structured integer programming model, called the multiple-choice nested knapsack model, is developed in this paper. The model is characterized by variables which are partitioned into multiple-choice sets and resource constraints which are nested across the multiple-choice sets. The...

This paper considers the problem of optimally locating multi-activity facilities whose activity compositions are also to be determined. It is assumed that there are fixed costs associated both with establishing facilities and with including specific activities at the locations. This problem is...

In this paper, we describe an integer programming algorithm for assigning tasks on an assembly line to work stations in such a way that the number of work stations is minimal for the rate of production desired. The procedure insures that no task is assigned to a work station before all tasks...

Given n items, each having a weight w<sub>i</sub>, and a container of capacity W, the Subset-Sum Problem (SSP) is to select a subset of the items whose total weight is closest to, without exceeding, W. The paper presents a mixed approach (depth first search-dynamic programming) to the exact solution of the...

This paper addresses the time management problem confronted by sales representatives. The sales representative planning his itinerary must decide the best way to ration time among the accounts comprising his territory. The time management problem is formulated as an integer program whereby each...

Testing and comparison of integer programming algorithms is an integral part of the algorithm development process. When test problems are randomly generated, the techniques of statistical experimental design can provide a basis around which to structure computational experiments. This paper...

The most commonly used penalty in branch and bound approaches to integer programming is the Driebeek--Tomlin penalty. It has been used successfully in solving fixed cost linear programs by Kennington and Unger and by Barr, Glover and Klingman. It is well known that the Driebeek--Tomlin penalty...
