Abstract

To solve the problems of multi-objective control, objective quantification difficulties and computational complexity existing in the construction management, the construction system reliability was introduced into the project management. The process of construction project was divided into several units of work based on system decomposition theory. And the reliability of each unit of work was calculated. Then, the system reliability was optimized by the improved firefly algorithm. To avoid that the basic algorithm is highly depended on the initial solution and easy to fall into local optimum at later stage, the dynamic population firefly algorithm was proposed. Engineering practice shows that the improved algorithm has higher convergence speed and accuracy of optimization. The study provides a novel method for effective construction management.

Keywords: Construction system, firefly algorithm, improved algorithm, management, multi-objective optimization, reliability.
