Duration, cost and quality are three important main indexes to measure the comprehensive benefit of the construction engineering project, the comprehensive equilibrium optimization of which is great of significance. With simple process and clear results, non-radial super-efficiency DEA is an algorithm for studying the input and output, which considers the resource constraints and decision-maker preferences. By introducing this algorithm into the field of comprehensive optimization of engineering project, the multi-objective comprehensive optimization model of quality, cost and duration is established and the solution is obtained by using non-radial super-efficiency DEA model, thus completing the order of different construction schemes and realizing comprehensive optimization of engineering projects. Finally, through one application example, the solution is obtained by using LINGO software, which has proved the effectiveness of the optimization method and provided support to the decision-making of the project.
