考虑运营期收益的工程项目工期—费用动态优化

Time-Cost Dynamic Optimization for Projects Considering Income in Operation Period

工程项目的建设期和运营期之间存在着对立统一的关系。项目建设期缩短,提前竣工投产,运营期收益将会提高,但同时也会造成建设期费用的增加。论文将工程项目工期一费用优化与项目的财务评价相结合,在考虑资金时间价值的基础上,结合运营期大型设备更换对运营收益的影响,建立以项目全寿命周期经济效益为目标的工期一费用动态优化模型,并通过案例验证了该模型的必要性与可行性。

There is a relationship of unity and opposites between the construction and operation period of the project. When the construction period of the project is shorten, and the project is put into production in advance, the income of operation period will be increased, at the same time, it will cause the increase of construction costs. Combining time-cost optimization with the financial evaluation of the project, on the basis of considering the capital time-value, paper combining with the impact of large-scale equipment replacement on the income of operation period, establishes a time-co st dynamic optimization model with economic benefits of full life cycle as the goal and proves the necessity and feasibility of the model combined with the case.
