Application of the improved multi-attribute group decision model based on TOPSIS to select construction-agency

Government investment projects play a pivotal role in socialist economic construction, and government indicate clearly that implementation construction-agent system in government investment projects. The key of implementation construction-agent system is to select a professional construction-agency by open competition. We know that science selecting system can control the risk source of government investment projects effectively, and evaluation and determination bidding is the critical process of tender, so the core problem of evaluation of bidding is how to select a rational, scientific decision model which to select optimal solution from finite solutions. In order to increase the efficiency of construction-agency evaluation, the improved multi-attribute group decision model based on TOPSIS is proposed in this paper, we adopt the Minkowski distance to improve TOPSIS model, which solve the over weighted problem in the original TOPSIS model. Finally, a representative case to illuminate the application of the model, which picture the calculation procedures and verify the operability of the model, the model is an effective method to evaluation construction-agency
