摘要
针对考虑资金时间价值因素的多资源均衡优化问题,构造了不考虑资金时间价值的多资源均衡优化模型,实现了项目中多种资源均衡的静态优化,在考虑资金利息的情况下,建立了资源资金的优化模型．在上述两种模型的基础上提出了考虑资金时间价值因素的多资源均衡优化数学模型；阐述了遗传算法的改进方法,提高了算法的性能,并在此基础上提出了基于改进遗传算法的模型优化求解流程；通过工程实例分析,其成果在工程施工多资源均衡优化当中的应用表明,本文所提方法可行且有效．
Aiming at the optimization of multi-resource balance considering time value of funds, the optimization model of multi-resource balance not considering time value of funds is constructed, the static optimization of multi-resource balance in project is realized, and the optimization model of funds for resource is founded considering interest of funds, Based on the above-mentioned models, the mathematic optimization model of multi-resource balance considering time value of funds is proposed; the improved genetic algorithm （GA） is expounded, and the capability of GA is enhanced; furthermore, the flow chart of model optimization based on improved GA is presented. Practical project analysis is done, and the successful application to the optimization of multi-resource balance in engineering construction shows the feasibility and effectiveness of the proposed method.
