Research On The Dynamic Schedule Optimization Of Construction Project On The Condition Of Minimum Cost/Maximum Benefit.

The time value of capital in schedule cost optimization and the influence of the income of running period to schedule cost optimization of engineering project is mainly studied in this paper.On the basis of application of the time scale networks in schedule optimization, improved bar chart and improved GA is used in the statistic schedule cost optimization firstly, to obtain the schedule planning with minimum statistic cost.Secondly, the time value of capital is considered, the dynamic schedule cost optimization is researched in this paper. According to different networks, with reasonable index, dynamic models are set up systematically from different positions (owner/contractor); and the schedule planning with minimum dynamic cost is obtained through improved GA.Thirdly, with the consideration of the income of running period, the whole optimization is researched on the position of owner of construction projects. The relationship is analyzed between the income of running period and construction duration; then, the whole dynamic optimization model is set up; last, the schedule planning considering the income of running period is obtained through improved GA.With the reference to the whole optimization, authorized running project is researched: dynamic whole optimization model is set up on the basis of firm authorized running duration; improved GA is used to solve the problem with a case. Also, referring to the whole optimization, on the position of contractor, the dynamic whole optimization is studied on the condition of bonus for pre-completion: the dynamic whole optimization model is set up; the relationship between bonus and duration is discussed.In the end, the conclusion that the result of the whole dynamic optimization is the most accurate is drawn up.The statistic schedule cost optimization, the dynamic schedule cost optimization and the whole dynamic schedule planning optimization is researched in this paper, and the result of the paper can be referred when the construction planning is selected.
