Study Of Mantenance Spare Parts Classification And Inventory Control In F Fharmaceutical Company

Maintenance spare parts classification and inventory control is an important work of spare parts management. Scientific and effective operation is not only beneficial to the effectiveness of equipment maintenance, but also to seek a reasonable maintenance spare parts inventory through predicting spare parts demand accurately by using scientific stock strategy, so as to cut spare parts inventory cost as much as possible and increase economic benefits. Therefore, it's very important and necessary to make an in-depth study on maintenance spare parts classification and inventory control in F enterprise.Based on the analysis and discussion about the current problems of maintenance spare parts management of biological fermentation system in F enterprise, this paper does research on the maintenance strategy, maintenance spare parts classification and inventory control of biological fermentation system. The main target is to cut maintenance spare parts inventory cost as much as possible while to keep the equipment reliable and production continuous. The specific research content is as follows:First, this paper analyses the maintenance characteristics of maintenance spare parts management of biological fermentation system. And then, it discusses maintenance strategy classification and the problems of maintenance strategy in biological fermentation system. After that, it puts forward to the decision-making process of maintenance strategy. All of above is to pave the road for maintenance spare parts classification and inventory control.Second, this paper discusses traditional ABC classification, four-quadrant classification based on maintenance characteristics of maintenance spare parts and two stages of maintenance spare parts classification. Among them, two stages of maintenance spare parts classification of biological fermentation system is the main research content. The first stage is equipment classification that can be divided into 2 types: critical and noncritical equipment based on fuzzy analytic hierarchy process(FAHP). The second stage is spare parts classification that can be divided into 2 types according to maintenance strategy: corrective maintenance and preventive maintenance spare parts. After that, cross the equipment classification result and spare parts classification result to 4 types.Third, this paper proposes different inventory control strategy for different type of maintenance spare parts of biological fermentation system based on two stages classification. The specific research content is studying an inventory control model of critical and noncritical equipment's corrective maintenance spare parts in consideration of EOQ and the least quantity, and studying zero inventory cycle model of critical and noncritical equipment's preventive maintenance spare parts.
