비용 제약하에서의 소모성 동시조달부품의 최적구매량 결정 = Optimal Provisioning Quantity Determination of Consumable Concurrent Spare Part under the Fund Limitation

다국어 초록 (Multilingual Abstract)

In this paper we consider the CSP requirement determination problem of new equipment(machine) system. For the newly procured equipment systems, mathematical analyses are made for the system which is constructed with the consumable parts to derive the associated CSP requirement determination model in mathematical expression. Based on these on these analyses, a mathematical model is derived for making an optimal CSP requirement determination subject to the constraint of satisfying any given fund limitation. 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 concept in CSP is defined and the relation between the general system availability and the operational availability is established. Secondly, the problem is formulated as the operational availability maximization problem that should satisfy the fund limitation, and then, using the generalized Lagrange multipliers method, the optimal solution procedure is derived.
