The use of multiple control limits and multiple corresponding levels of response for processes is an effective way for statistical process control when different assignable causes exist which lead to different out-of-control states of the processes, and different restoration procedures. This...

This paper proposes a detailed model of the costs and benefits to producers and consumers of product warranty. Three common types of product warranty contract are considered. In addition, we explicitly allow for randomness in consumer repurchase behavior and for the possibility of an independent...

Blood Inventory Management has attracted significant interest from the Operations Research profession during the last 15 years. A number of methodological contributions have been made in the areas of inventory theory and combinatoric optimization that can be of use to other products or systems....

Once again we show that the analysis of a very simple artificial example contrived by its authors for a general indictment of all chance constrained programming is itself in error. Proofs and further references are supplied below along with a discussion of other deficiencies and ambiguities in...

We have developed a stochastic representation of the pharmacologic treatment of hypertension that is useful in predicting the outcome of various therapy protocols (sequences of antihypertension agents). Important variables (compliance, pharmacologic potency, incidence of side effects, symptoms...

In this paper we compare the performance of one-officer and two-officer police patrol units using travel time as the measure of performance. We estimate travel times under two different models of dispatch operations. The first model reflects most existing dispatch systems in which patrol units...

This paper develops a one-dimensional cutting stock procedure which will minimize material wastage when a batch of small pieces are cut from several long pieces. The problem differs from the classical one-dimensional cutting stock problem in that the dimensions of the material to be cut are...

One emergency service system model that has undergone extensive development and testing is the hypercube queuing model and its approximate analog, which were developed by Larson. The model estimates key system performance measures, such as individual unit workloads and travel times. One...

This paper draws from two separate research traditions in marketing theories of consumer behavior: multiattribute expectancy-value models and stochastic choice models. A behavioral basis for the observed brand-switching phenomenon is found in the multiattributed evaluation of alternatives and...

This paper presents an algorithm for deploying a crime directed patrol force. The optimization problem is formulated as the allocation of N patrol among R high crime regions so as to maximize the weighted probability of a patrol intercept of a crime. The algorithm has full sensitivity analysis...
