Research on System Maintainability, Availability, and Cost Models.

Abstract

Most of the mathematical models and analyses of availability and availability (reliability) warranties have considered individual units of equipment or collections of such units in which the availability of each unit is desirable and important. Bulk availability differs from unit availability in that the individual units are not the primary consideration but rather the number of units that are available at a given time. The present research deals with another kind of availability consideration which considers a large number of units rather than a single item. Bulk availability warranties are defined as costs incurred by the contractor when the number of available units falls below contractually specified levels. The bulk availability model can be employed as useful tool in tradeoff analyses between manufacturing, logistic, and warranty costs. By using several versions of a proposed model, with different parameter values, a set of possible availability functions can be generated.
