Research On Inventory Cost About The Amount Of Reverse Logistics In Supermarket Chains

Supermarket chains in China started lately and their equipments are both backward and low level of information-based. The goods in supermarket chains update quickly and it is difficult to estimate accurately about order quantity. Such situation causes product overstocked which cannot return to suppliers immediately. Therefore, the figure of reverse logistics is significant which damages the firm’s economical avenue. This dissertation studies the cost of reverse logistics stock for supermarket chains under the background provided above and suggests some improving advices while identifying relevant impact factors.The paper defined some relevant concepts like supermarket chains, reverse logistics and, etc, and reviewed the relevant literatures about anticipation methods for amount of reverse logistics and stock theory. Considered each model’s feature and the characteristic of supermarket chains, the paper chose exponential smoothing method forecasts model as the theoretical evidence. Combing with the features of supermarket chains the paper classified the factors as the basis for model construction through considering the reasons and ways of products or packing entering to reverse logistics system and the difference of dealing ways of recycling goods. The paper built the reverse logistics stock cost model for supermarket chains on the basis of exponential smoothing anticipation model. This model mainly concerned about the those significant factors, such as exponential smoothing coefficient, tendency smoothing coefficient, seasonal smoothing coefficient, return rate, damage rate and defect rate ,etc. In the case study, the paper selected 20 kinds of representative typical products from the reverse logistics of supermarket chains for empirical analysis and calculated the total stock cost through MATLAB programming. Then the paper selected no.13 product to adjust its various coefficients and compared estimate results to check the level of each factor’s influence. Finally, the paper classified those 20 kinds of products by considering the impact factors and suggested corresponding advice according to various kinds of products and achieved the aim of declining total reverse logistics stock costs.The application of the study outcome has excellent social and economical effects on decreasing supermarket chains’reverse logistics cost and enhancing development of supermarket chains in our country.
