A Case Study on Joint Replenishment Problem for Slow Moving Spare Parts in a Nuclear Power Plant

In most circumstances, the stock-out cost of spare parts can´t be confirmed exactly because of the special characters of continuous production. Service level constrained (s, c, S) inventory model with continue review policy for joint replenishment is analyzed in a nuclear power plant. Comparing with (s, S) policy, its advantage is tested through practical case. At the same time, sensitivity analysis is accomplished and the corresponding means for inventory optimality are put forward for this kind of spare part. The proposed model is successful in decreasing inventories holding costs significantly by modifying the unreasonable purchase applications while maintaining the predefined service level.
