Study Of Inventory Management Based On Auto Industry Powertrain Plant

In recent years, the domestic auto industry competition is very fierce, though China hasbecome the largest auto production and sales in the global market. The competition core byproduct and service soon transforms the time and cost competition now. Auto enterprisedeeply care much about internal inventory management, especially in previouslymisunderstanding spots, which in the eyes of auto enterprises have become an importantProfit.How to establish reasonable safety bank is the prior condition of inventory management.But related impact factor of safety bank such as the market undulate, the conveyanceundulates, supplier quality problem etc. all are discrete type random variable, this brought abig trouble to make reasonable safety bank., Up to now we haven’t found a standard methodto set up safety bank. Usually we can only set up the safety bank based on experience andcharacteristics of enterprise.In this text I will deeply analysis SGM powertrain plant’s inventory composing and theactual situation of inventory management. Studying the safety bank principle by classificationbased on the inventory function and specific weight. To part inventory, product inventory andWIP inventory it is feasible to use statistical methods to probe each factor and safety bankprinciple in mathematical relationship and established relevant mathematical model. It isimportant pay attention to combine optimization of mathematical model and enterpriselogistics system in order to capture a safety bank principle setting solution for auto enterpriseby scientific methods. For material stock we established mathematical formula based on thestatistics data of4key factors. Finished part stock we used Min-max method to control. Andthe WIP stock we used Witness, the professional and popular simulation software to analyzethe bottle net in line and evaluate the economical WIP stock. The studying achievement canhelp auto enterprise establishes reasonable stock.
