The radio frequency communication environment, for example, in large vessels, aircraft, space vehicles, and satellites, has become increasingly complex as more and more transmitters, receivers, and corresponding communication nets are being added to perform multiple functions. This paper...

The problem of choosing an optimal initial capacity expansion from a finite number of durable facility sizes is affected by potential future expansion decisions. As we consider such expansions over longer and longer study horizons, the optimal initial facility choice can fluctuate due to...

A model for measuring the economic benefits of irrigation system development over a depleting aquifer is presented, along with related methodology for detailed long-range farm planning. The paper considers management issues, such as distribution system configuration, drilling policy, area...

The multi-item joint replenishment problem is generalized to allow ordering costs to be dependent on the specific items jointly supplied. A fixed cycle approach is examined in which all the items of a group are always jointly replenished. A dynamic programming algorithm is developed for...

Motivated by an application in a public utility, the credit screening problem is re-examined from a decision theoretic viewpoint. The relationships between several alternative problem formulations are explored, and compared to the classical linear discriminant analysis (LDA) approach. Several...

A number of models have been developed in recent years for the allocation and deployment of urban police units. However, these models are not directly applicable to the state highway patrol counterparts. Although urban police and the state highway patrol are both law enforcement agencies, an...

The process of converting a tree into finished lumber involves several interrelated steps. The two of greatest potential for improvement are cutting the felled tree into shorter logs (called bucking the tree) and sawing the bucked logs into lumber. Unlike previous work in the area, this paper...

Optimal solutions for the dynamic lot-sizing problem with deterministic demands but stochastic lead times are "lumpy." If lead time distributions are arbitrary except that they are independent of order size and do not allow orders to cross in time, then each order in an optimal solution will...

A model developed to aid a state-level resource allocation process in the United States Department of Agriculture Special Supplement Food Program for Women, Infants, and Children (WIC) is presented. The model is formulated as a linear integer goal program, utilizing service levels for six...

This paper presents a mathematical model of sequential investment behavior under conditions of uncertainty. The model addresses the problem of an investor with access to a limited pool of capital, who makes sequential decisions on long-lasting investments, under uncertainty as to the timing or...
