Research on approach for determining mark-post of logistic system based on the fuzzy set theory

Evaluation, determining level of mark-post and performance improvement are three important steps in benchmarking. In this paper, for two master businesses (distribution and sorting) in one logistics system, benchmarking implementation strategy is designed, and it is key to discuss the problems about system evaluation and mark-post quantification. Thereinto, the system is evaluated by means of fuzzy set theory, trough comparing evaluation result, a score of ideal performance is set. Furthermore, according to the route of hierarchical calculating of fuzzy evaluation, a set of improved fuzzy values for each operation at the bottom of system hierarchy is reckoned against fuzzy evaluation calculating route. Finally, it expatriate on the meaning of benchmark combined with DEA and the effect of small mark-post (virtual DMU₀ ) for DEA
