One inventory optimization model for supply chain was built based on fuzzy logic to properly model the uncertainty associated with both market demand and inventory *** fuzzy process was represented and the new inventory control approaches were applied in cases *** simulation and analysis as to both single stage and multi-stage stock with fuzzy controller or classical controllers were separately *** comparative simulation,the results prove that the new inventory method can obtain better performance such as lower total cost,more stable inventory level and so on.
