“The Economics of Integrated Logistics Support” is a treatise which discusses techniques for evaluating the economics of integrated logistics support as applied to the selection of support systems. The prime objective here (and in the utilization of such techniques) is to develop methods for generating quantitative data for cost optimization of support philosophy including test equipment selection, manpower factors, inventory factors, facilities, deployment, and equipment maintenance considerations. A deterministic model is described, including the enumeration of its capability in terms of versatility to evaluate many alternatives rapidly and inexpensively since it presently exists in the form of an operating computer program. This includes sensitivity testing of significant parameters to evaluate the cost effectiveness trends of support alternatives. Input data requirements are also reviewed along with various cost effectiveness indices used to judge the system’s worth based on quantitative results representative of specific applications.
