The Design And Optimization Of Inventory Pooling System In Group Corporation

Inventory management is a very important activity in every business organization.It is why commercial organization must hold a certain amount of inventory that they can make sure the continuity of production and sales,and reduce the risk of stagnation caused by shortages which has important significance to meet customer needs in time and maintain customer loyalty.On the other hand,it means the occupation of organization resources to hold a certain amount of inventory,which generates a variety of related costs.Inventory is both angel and evil,so it is always a hot research topic how to optimize inventory management.Considering the synergistic effect and scale effect of group company,we choose group company as research background of inventory management.Based on a review of historical documents and the related theories,the.article takes inventory pooling as the theoretical basis,designing a two level group inventory pooling system,which is combined with the inventory pooling management of the parent company and the inventory sharing management of the subsidiary company.We makes a comparison of the amount of safety stock between centralized inventory management and decentralized one,with the method of mathematical analysis.We draw a conclusion that as long as the customer needs is not completely positive correlation,it can reduce the amount of safety stock under the premise of centralized inventory management.Although centralized inventory can reduce the safety stock,there are also some side effects that it is extending the customer waiting time,thereby affecting the level of customer service.On this basis,the paper gives some management strategies and discusses the types of inventory which are suitable for centralized inventory management.In other words centralized inventory management applies more to the inventory which is consumed slower and costs more.The paper focuses on the decentralized inventory of the subsidiary company.In first it discusses about the transfer pricing problem of centralized inventory and analyzes the application scope,advantages and disadvantages of various pricing policies.Then this paper uses the game theory to establish the Stackelberg game model of the transaction behavior of the subsidiary company in the mode of shared inventory.We get equilibrium solution with Chaos search optimization algorithm in the method of bi-level programming.It is found that the subsidiary is more conductive to the overall interests of the group than in the case of mutual cooperation.Therefore the parent company should guide the sharing behavior of the subsidiary,creating trade rules and some necessary systems of rewards and penalties to balance overall benefits of parent company and reasonable interests of subsidiary.On the basis of demonstrating the rationality of the inventory system,this paper discusses the specific management methods to realize the share inventory system of the group company,including the management strategy,organizational structure and the construction of information sharing system.Finally,the paper summarizes the research conclusions and innovations,limitations and future research directions.
