System Modularization to Minimize Life Cycle Costs

Abstract

When designing equipments, particularly electronic equipments, there is a need to collect components into integral groups called modules. A network can be arbitrarily decomposed into modules, but an optimum modularization would minimize the life cycle cost (LCC) of the system. This research was directed toward that goal. The method developed is a heuristic and no attempt has been made to establish its optimality (although no counter examples are known). The problem is approached as one of decomposing a network subject to constraints. The problem may be stated as: Decompose a system to minimize the life cycle cost subject to physical constraints, a mean-time-to-repair constraint and establish spares to meet an availability constraint. A computer routine has been developed and explained. A flow chart is included.
