Study On Location Evaluation Of Chain Convenience Store Based On Soft Set Theory

In the 21st century, with the rapid expansion of China’s economy, people’s living standards improve. But the pace of life is speeding up gradually, as a result, the consumers’lifestyles and shopping habits have gotten changed, and the convenience stores developed rapidly. The success of modern convenience store chain depends on the completion of the process which contains picking, inventory, site selection, store, display and service. Comparing with hypermarkets, supermarkets and other retail formats, convenience stores are more sensitive to site convenience store due to the small size and small business district. If the shop site properly, it means that it enjoys "location" advantage. So, the study for convenience store chain site assessment is necessary.In this paper, the methods that contain literature review, questionnaires, field surveys are used to explore the related factors, which influence the selection process, including:demographic factors, transport factors, competitive factors, their own factors, business factors. But some factors to consider in the convenience store location process is difficult to quantify. Due to the small size of the convenience store and limited capital investment costs, taking into account the uncertainty and ambiguity, this paper chose a universal solution for the uncertainty of information soft collection. Since that there isn’t any restrictive conditions when the soft set theory describes the object approximately, the theory is easy to use and practice. Through the establishment of the decision-making model with soft constraints and soft targets, that using soft computing method has so many advantages, such as easy to handle, robustness, better coordination with the reality of the system and a low cost. Firstly, this paper reduce the selected factors using soft-set method, then establishing an evaluation system of the siting factor for the location of a chain of convenience stores. Secondly, taking into account that the particularity of the value of parameter mapping in soft set, the evaluation model of soft set theory under incomplete information is used to calculate and analysis the results of the reduction. Finally, to verify that whether the soft set theory approach can be applied in the selection process in the chain of convenience stores or not, the calculated theoretical results should be compared with the actual results of the survey sample empirical test.The study in this paper enriches the theoretical content of the site for a chain of convenience stores. For the uncertainty in the site selection process of the chain of convenience stores, a soft set theory is used to construct site evaluation index system of the chain of convenience and test its practical operability. The study has a certain reference and guidance on Evaluation Research and Practice store location.
