Abstract: The successful implementation of business process reengineering (BPR) for an enterprise should be guided by the quantitative methodology, so that the reengineering results can be clearly predicted and acknowledged, however， at present there is no perfect model yet to deal with the tradeoff between time, quality and cost as a basis of reengineering and optimization. In this paper, based on the stair-like CIM architecture (SLA) giving the model framework of an enterprise, the concept of BPR is further elucidated, and the multicriteria linear programming models are established to tackle the tradeoff between time, cost and quality by introducing the concept of unit time cost corresponding to different quality levels (UTCQ). Reengineering and optimization according to the models presented in this paper can avoid the blindness and aimlessness for BPR, support the continuous improvements of business process, and thus effectively reduce the investment venture for BPR.

Key words: critical path method with constraints, multicriteria linear programming, process view, business process modeling, business process reengineering
