Research On The Inventory Control Of Electronic Products Based On Closed-loop Supply Chain

As the increasingly concerned about the issue of environmentalprotection, increasingly importance has been attached to the retrieve and recycle ofwaste materials. Meanwhile, many countries strengthen enforcement of relatedlaw-making, Awareness of resource recycling in the whole society also improves.Under this background, thus a new supply chain mode gradually generates, whoseflow direction is from consumers to producers, namely the reverse supply chain. Asthe organic combination between traditional forward supply chain and the reversesupply chain, a new supply chain management mode emerges, that’s the closed-loopsupply chain management.What’s more, the electronic products due to some of its own characteristics,which are fastly becoming obsolete, components containing metal and chemicalsubstances that can do harm to the environment and so on, therefore the treatmentafter using is more urgent to take into account. Still inventory control is not only themain point of traditional forward supply chain management, there is morecomplicated and important in the closed-loop supply chain for the existence reversesupply chain, as a result, research in view of electronic products enterprises’s ordistributor’s inventory control based on closed-loop supply chain is very necessaryand meaningful.Just based on the above-mentioned background, the article gets its researchcontents as well as methods after reviewing related research at home and abroad, ittakes the core of “double source’’ inventory replenishment, firstly presents the relatedbasic theories associated with the subject, main parts are as follows:(1) Theconnotation, structure, driving factors of closed-loop supply chain as well as thedifference and relationship with traditional supply chain management;(2) Theimplication, classification of problems, composition of cost of inventory control aswell as strategy and main model of inventory control; Secondly, on the premise of fullconsideration about electronic products’ value attenuation factor, the articlerespectively takes the demand of external market and return rate of electronicproducts are deterministic or not into consideration, as well as whether consider therepair time of reflux electronic products, separately establishes single-stage as well astwo-echelon inventory control model under closed-loop supply chain; Finally, we getthe optimal decision variables or simultaneous equations by solving the modes, what’smore, the article discusses the effectiveness of the model and analyzes the decisionvariables’ sensitivity with change of external parameters by using related data with thehelp of software Mathmatical5.0, and obtain some valuable conclusions.The article takes such factors as electronic products’ value lapse, the repairproducts may not be up to the same value and homogeneity as new products together with return products’ disposal treatment and so on which are seldom involved intoaccount, thus will enrich the inventory control theory under closed-loop supply chainmanagement, meanwhile to some extent, provide reference to electronic productsenterprises who implement the closed-loop supply chain management.
