The Optimization Of W-I-P Production And Inventory Management In YZ Automotive Interior Trims Company

Interiors are important components of automobile parts. Its characteristic is a single model of deployment of rich, high unit value. In order to meet the market competition, pressure to reduce their inventory of OEM customers the consideration, generally requires interior parts business in JIT supply form. To meet the supply needs of multiple configuration and discrete, interior parts companies often need to maintain a high inventory of finished products and work in process, and resulted in increased inventory costs. Production planning is the main line of production organization, its reasonableness will directly determine the merits of the overall operational efficiency of enterprises. However, interior parts of production planners plan, especially when determining the production lot, mostly relying on experience and subjective judgment, lack of scientific basis for the theory. Therefore, the premise of how to meet customer needs, develop scientific production and inventory strategy and how to improve current levels of management in order to achieve the policy's automotive interiors businesses is an urgent need to address the problem.Paper for a interiors pieces enterprise of production features, to injection pieces of IP lower as breakthrough, to optimization General in products inventory and determines injection pieces of IP lower of economic production quantity for target, while through benchmark management of means, on group internal typical company of corresponding situation for analysis compared, eventually determines inventory target; on the through mining at this stage all of cost factors, generation into EPQ model calculus get injection pieces of IP lower of economic quantity, And set up the enterprise's economic production quantity model based on cost optimization. Meanwhile Fishbone diagram form, identify obstacles that affect optimization work, and phased implementation of recommendations for the guidance is given.Finally, OEM customers "Chain of pearls" of the new production model has been analyzed, will particularly impact on the entire automotive industry and interior parts business is analyzed, and stood in the interiors business perspectives in terms of production and inventory management of alternative policies, eventually hoping to help once again enhance the management level of enterprises.
