A Rough Set Method for Supplier Performance Evaluation in E-Business

This paper proposes a new model for supplier performance evaluation in e-business. This model uses balanced scorecard to define the performance evaluation structure in an enterprise. The evaluation is focused on key performance indicators that are calculated from supplier business transactions. We use rough set theory to select key performance attributes at different levels in the evaluation structure and calculate the weights of the selected attributes. We present a performance evaluation process that can be easily implemented in an enterprise. We use a simplified example to show how the new process is used to evaluate suppliers.
