Descriptions of the capabilities and uses of the model encompass typical applications, the role of judgment in using PCAM, and the major differences between PCAM75 and PCAM85 (PCAM85 is a modernized version of the original model developed in 1975). The discussion reviews general operation principles, preparation of a data base, data required for each patrol hour, calculation of performance measures, and prescriptive calculations. The user's guide to PCAM opens with an overview of program operation and then specifies how to enter commands, command format conventions, program vocabulary, and command definitions. The guide also explains error conditions and selecting an objective function. The appendixes contain information on PCAM's calculations, PCAM reference sheets, and addresses for further information. A glossary, 19 figures, and a 40-item bibliography are also provided. For an executive summary of PCAM's description, see NCJ 98719. For program description, see NCJ 98721.
