The Research On The Inventory Strategy Of G Company Under Environment Of Supply Chain

Under the mode of supply chain, inventory management is one of the most important parts of supply chain management. The level of stocks not only affects the operational cost, but also affects the service of entire supply chain. Inventory management methods under the environment of supply chain have been proposed, including vendor managed inventory(VMI), jointly managed inventory(JMI), collaborative planning, forecasting and replenishment(CPFR), but seldom practiced. Therefore, from the perspective of supply chain, this paper uses the joint inventory management method(JMI) to solve the problem of high inventory among G enterprise and distributors.G company is a manufacturing enterprise which produces household air conditioners. Firstly, the enterprise’s current inventory situation is analyzed from two aspects: external and internal supply chain, and some problems are pointed out. For example, regardless of consumer’s demand, G company takes pull strategy leading to overstocked products, repeatedly set up warehouses leading to low efficiency of logistics, as well as the G company and dealers do not trust each other, less information communication causing “bullwhip effect”, etc. According to above situation, through comparative analysis of several methods and combined with the actual situation of G company at the same time, JMI inventory management mode instead of traditional inventory management mode was applied and a two-level inventory based on JMI was established by consulting to multistage inventory strategy research. Some hypotheses are put forward and cost model before and after adopting JMI are established, considering consumer demand distribution, manufacturers lead time, shortage cost, inventory holding cost and transportation time. Two methods’ safety factor is computed through Matlab software and total cost before and after adopting JMI are worked out. Compared with the traditional optimization strategy, that the cost of manufacturer increase a little, yet the cost of distributor is greatly reduced is discovered. Therefore, in order to solve the contradiction between the manufacturer and distributor, Inventory cost allocation mode according to the proportion is put forward.Finally, Flexsim simulation model based on jointly inventory mode is established in this paper. It assumes that the system exists one to many system(one air conditioner external unit to several internal unit), and air conditioner mating, capacity constraints, facility and the staff, conveyer’s working time are considered to analyze this system in order to give companies a more practical reference. As the home appliance market go downward and the sales is in decline, high inventories have become enterprise’s shortcomings among various house appliances companies. High inventory problems seriously restrict the development of the enterprise, so how to solve the high inventory problem becomes the main problem in home appliances industry. Hope the outcome in this paper will supply reference value to relevant electrical appliances enterprises on inventory management.
