Research On The Material Management Mechanism Of Multi-variety And Small-batch Aerospace Products

Diversified requirements for aerospace products,make multi-variety,single small batch production mode become the mainstreamo?This mode of production is characterized by:material type?small batch?low repetition rate of production?the process often changes.At the same time?high quality requirement?long ordering period and limited purchasing channels also bring greater difficulty to material management?This,in turn,adds to economic costs,given the need to keep some inventory in the production cycle?Therefore,it is of great practical significance to carry out research on material management improvement of aerospace products?This paper takes the company's multi-variety and small-batch aerospace products as the research object,focus on the weakness of material management,the theoretical methods of production layout optimization and material inventory management are compared,flexible production unit of metal products is proposed and constructed,dynamically adjust production capacity and improve the efficiency of logistics turnover;Extracted using SLP method and combining with computer simulation to optimize production capacity in order to improve the material flow cycle,increased the capacity of the pipeline nearly four times,reduces the inventory quantity of pipes;Based on delay strategy,the structure of plate and pipe products customized separation point is studied,make the material can be used to the transition of management organization order;Using ABC method and combining with CVA the classification method of space products material,sorting out the need to study the object-components and pipes.In the components inventory data in recent 3 years and pipe use number based on the analysis and sorting,the safety stock and the optimal reorder point data,and to the existing management style and research method of this article has carried on the comparison and analysis,for the precise calculation in aerospace materials management provide the basis for the safety stock;The factors affecting material shortage are analyzed,to put up materials emergency management?Research and application of optimization,inventory control strategy and material response management of production organization mode,it provides an effective means for the improvement of space product material management in many varieties and small batches and has a broad application prospect?...
