A Research On Spare Parts Management Of Suzhou Rail Transit

With the continuous increase of national infrastructure investment,rail transit construction throughout the country has entered a period of rapid development,but the construction project of rail transit facilities is high cost,return on investment cycle is long,and the maintenance cost after all kinds of operation will increase exponentially with the opening of the Wire network,among which,The management cost of operating spare parts accounts for a high proportion of the expenditure.Therefore,the optimization of spare parts management is a major entry point for rail transit enterprises to reduce their efficiency and efficiency.Taking the spare parts of Suzhou Rail Transit as the research object,this thesis first combs the present situation of the management of the operating spare parts,expounds in detail the classification mode,management flow,inventory situation and management characteristics of the current spare parts,and deeply analyzes the high inventory cost,indistinguishable importance,low sharing degree of the current management mode,The procurement process is cumbersome;then according to the above problems,the ABC spare parts classification method based on AHP is proposed,the spare parts of the signal interlocking system are selected,and the classification results are compared with the traditional ABC classification.Finally,the optimal management measures based on spare parts classification are put forward,including the optimization of purchasing mode,Optimization of inventory sharing,improvement of personnel level,and optimization of construction handover spare parts management.This thesis constructively puts forward the procurement management mode of class A spare parts using single source+joint procurement+Joint inventory management,the procurement management mode of class B spare parts using bidding procurement+ framework management,and the purchase management mode of class C spare parts using the common comparison selection or bidding purchase+VMI strategy.Through multi-angle,all-round management promotion,can effectively reduce the inventory cost of rail transit operation spare parts,improve procurement efficiency,ensure product quality,while maintaining the stability of spare parts inventory,so as to significantly improve the management level of Suzhou Rail transit operation materials.At the same time,through the research of this topic,we can provide some reference for other rail transit operation Enterprises in the industry in the management of spare parts.
