—Along with the prosperity of market economy, the improvement of comprehensive the corporate strength, large and medium-sized projects become more and more. On the other hand, the tendering and bidding market has become increasingly fierce, the benefit of the enterprises who win the bidding generally cannot be too high. According to the main evaluation factors in the evaluation of bid, this paper established a quantitative evaluation index system, using the quantitative indicators as variables, built up the integer programming bid evaluation optimization decision model with comparative benefit maximization of competitive bid unit as the objective function and the general requirements of umbrella project to subproject as constraint conditions. According to the characteristics of the problem of sub-contractor selection in multiple subprojects, this paper put forward the corresponding algorithm of genetic algorithm. Examples show that the algorithm is effective.
