다국어 초록 (Multilingual Abstract)

In this paper we consider the CSP requirements determination problem of newly procured equipment system. The CSP we deal with in the paper are restricted to the demand-based spare parts. For the newly procured equipment systems, mathematical analyses are made for the system which is constructed with the repairable items to derive the associated CSP requirement determination model in mathematical expression, respectively. Based on these analysis, a mathematical model is derived for making an optimal CSP requirement determination subject to the constraint of satisfying any given objective availability. We assume that the failure of a part follows a Poisson process. Firstly, the operational availability concept in CSP is defined and the relation between the general system availability and the operational availability is established. Secondly, the problems is formulated as the cost minimization problem that should satisfy the objectine operational availability, and then, using the generalized La-grange multipliers method, the optimal solution procedure is derived.
