The Application Research of Rough Sets and BP Neural Network in Supply Chain Performance Evaluation

This paper sets up a supply chain performance evaluation model based on rough sets and BP neural network from knowledge discovery and data mining perspective.It gives a supply chain performance evaluation example,firstly reduces its index based on the balanced scorecard system,and then inputs the reduction index to BP neural network for intelligent training.Finally,it inputs the evaluated sample to the trained BP network and gets supply chain performance evaluation value.The evaluating result is matched with the actual result.
