Optimum Supply and Maintenance Model Release 2.0 User's Guide.

The OSAMM is designed to simultaneously optimize support and maintenance policies for new equipment. Inputs to the model are limited to the types of information that should be available early in development when the maintenance concept is being formulated. The model determines optimal maintenance task distribution and replacement task distributions for the major items in equipment. It also compares the cost of throwing away an item with the cost of repairs. In making these decisions the model considers the spares, special test equipment and special repairmen that will be needed to support the maintenance policy. Other costs such as transportation, cataloging and documentation are also considered. Release 2.0 contains three run modes, one of which accepts up to three different options for each repair action. The improved model is able to trade-off among three repair methods. This capability can be used to analyze such repair actions as common, automatic, and special test equipment to determine how repair should be done as well as where it should be done. The original model remains as one of the run modes of the enhanced model, however. This the users guide gives a brief description of the model, defines the inputs required, and explains the output. It also contains a chapter which describes the various types of sensitivity analyses that can be performed using the model.
