Study on the Optimization Modeling of Construction Time Considering the Dependence of Durations

Abstract

In order to solve the problem of project time optimization considering the dependence of durations, and on the basis of the existing literature the Pearson product-moment correlation coefficient and the nonlinear structural equation model are adopted to measure serial duration dependence and parallel dependence separately in the construction projects, and which are used to update the duration data. The mathematical model of the optimization of construction time is set up while the cost as a constraint, at the same time the optimization model is modified by considering the duration dependence, and finally the time optimization is achieved by using genetic algorithm. By taking into account the optimization modeling of construction time considering the dependence of durations, an empirical study is carried out to get the ideal results. This method, which has good guidance and practicability, can be used to solve the problem of time delay in the actual project.
