Abstract: There was no quantification ways in current production logisitics evaluation system which was due to different operational status caused by the different production mode or production structure, from the concept of fuzzy entropy, the operational entropy model based on the element of production system was developed according to the principles of the information entropy and the definition of order degree. At the same time the operational evaluation system of production system was established on the basis of factors of production logistics system. In empirical study, the nodes of process routing actualized fore-and-aft cellular manufacturing in a workshop were taken as object and the order degree on the two different condition were finally solved by using the model of operational entropy and order degree. As a result, this quantification way to evaluate the orderliness of production structure was validated and application scope of operational entropy model was also extended.

Key words: logistics, entropy, production logistics system, evaluation, order degree
