Measuring the Operation Performance of Unattended Convenience Store Using a Two-stage SBM Method
This paper focuses on measuring the operation performance of unattended convenience stores, which is divided into two stages: economic sub-system and social sub-system. The approach, two-stage SBM model, is applied to evaluate the overall efficiency and sub-system efficiency of 33 unattended convenience stores in Chain. The main findings are: 1. The overall performance value is relatively low and fluctuates greatly, in which the economic is generally low while the social is slightly higher. 2. The two-stage SBM method has a stronger discriminating power than conventional black box method and identifies problems more accurately.
