Abstract
Comprehensive tradeoff control on quality, construction duration, cost and resource equilibrium is main aspect of construction project management, and is significant for improving the benefits of construction projects. In this paper, firstly the time-cost relationship model, the quality-time relationship model and resource equilibrium-time model are set up separately, objectives of quality and resource equilibrium are introduced to traditional time-cost optimization model for comprehensive optimization. Furthermore, multiple objective model of schedule is established by synthesizing single-objective models of quality and resource equilibrium. Then, based on TOPSIS, comprehensive optimization scheme is selected according to relative approach degree. Finally a case study is presented to verify feasibility and practicability of method.
