A new selection method for ERP of manufacturing enterprise was developed. Firstly, an evaluation model of ERP selection process was established, and an evaluation system for ERP selection was constructed by using balanced score card (BSC). According to benchmarking principle, the referred series was obtained for ERP selection. All the relative weights were calculated based on the analytical hierarchy process (AHP) technique. Then, the priority scheduling of ERP software was realized via the grey relational theory. Finally, a practice example analysis was carried on. The results show that the method is comprehensive, practical and operational for ERP selection.
