A method for modelling and evaluating supply chain performance using fuzzy sets

During the last decade, the supply chain management literature was well enriched. Many works dealt with the optimisation problem using dynamic programming or heuristics. In this paper, we propose a new approach based on fuzzy systems for modelling and evaluating performance of supply chain. Particularly, we consider here a framework of e-business industry. The concept of satisfying the request of the customers is studied and the underlying problems for managing this chain are discussed. After describing the elements of the model, theirs input and output parameters, we analyse results of simulation and optimise them in the aim of giving help to deal with the indistinct data met by the decision-makers.
