Research On The Spare Parts Inventory Optimization Of Continuous Manufacturer

Maintenance spare parts refers to the production enterprises in order to reduce therepair time, and achieve advance procurement and reserves in the warehouse forreplacement parts. Production enterprises in the daily management of spare parts areoften faced with this dilemma: If there are too many spare parts in the warehouse, it willcause the backlog of inventory, increase the warehouse area, enhance storage costs andabove all affect Working capital turnover; if the quantity of the spare parts are low, itwill affect the timely supply of spare parts, prevent equipment repair schedule, extendeddown time, make the enterprise production activities loss of economic benefits. Thegoal spare parts management is to ensure the provision of spare parts required byequipment maintenance, improve the reliability and economy of the equipment, as far aspossible to reduce spare parts inventory capital. Only scientific and rational storage andsupply of spare parts can make the equipment maintenance tasks completed botheconomical and reliable. Based on the analysis and discussion of the classification ofspare parts and the inventory management model under the environment of supply chain,this thesis focuses on the spare parts classification method based on fuzzycomprehensive assessment method, the ordering decision analysis model of the slowmoving spare parts, and the inventory control strategies of the fast moving spare partsand other aspects, the main contents are as follows:First of all, starting from the classification method and characteristics of spare parts,put forward the classification method of spare parts based on fuzzy comprehensiveevaluation, the spare parts can be divided into the slow moving and fast moving of twocategories, according to the characteristics of slow and fast moving of spare parts,respectively puts forward targeted way of spare parts management, and minimize thecost of spare parts inventory.Secondly, according to the characteristics of fast moving spare parts consumption,put forward JIT inventory strategy, and compared with EOQ purchasing model withprice discount, set up decision analysis model, analyze the inventory economic effect ofthe fast moving spare parts, for example is given to illustrate the superiority of theinventory model.Finally, according to the consumption characteristics of slow moving spare parts,for specified spare parts availability constraints, establish the objective function of a minimum unit time inventory cost, through analyzing the relationship between thereliability of equipment and ordering decision, and establish the ordering decisionmodel of spare parts to illustrate its validity and applicability through the exampleanalysis.
