DEA and TOPSIS combination model for the construction scheduling of urban road projects

The construction scheduling of urban road projects is a typical multiple stage and multiple attribute decision making problem. To improve the availability of the urban road planning and construction, a model with multiple stage and multiple attribute is proposed, which is based on the DEA and TOPSIS. The DEA method is used to calculate each DMU's relative efficiency, then the TOPSIS method is used to rank the relative efficiency, and the urban road construction sequence is obtained accordingly. In this model, the advantages of the DEA's superiority of evaluating with multiple inputs and outputs indicators and the TOPSIS's systematicness and comprehensiveness are utilized. And the shortcoming of the DEA's failure to rank all projects is avoided, which provides a new approach to this problem. Finally, an example is presented to illustrate the effectiveness of the proposed method.
