摘要:
 为达到工程项目效益最大化，实现工期与成本的综合优化目标，提出一种改进NSGA-Ⅱ算法与BIM5D结合的寻优方法，对工期-成本优化问题进行求解。考虑投产效益对成本的影响，完善了工期[CD*2/3]成本多目标优化模型。为解决NSGA-Ⅱ算法寻优过程中搜索空间小，准确度低的问题，在引进动态交叉、变异概率基础上，设计求解该模型的改进NSGA-Ⅱ算法。并将算法与BIM5D平台对接，进行施工工序及资金、资源曲线模拟，提高单一算法寻优实践性。案例分析表明，改进NSGA-Ⅱ算法与BIM5D结合求解工期-成本优化问题可有效优化进度和成本目标。
Abstract:
 In order to maximize the benefits of engineering projects and realize the comprehensive optimization goal of construction period and cost, an optimization method combining improved NSGA-Ⅱ algorithm and BIM5D is proposed to solve the problem of construction period cost optimization. Considering the impact of production efficiency on costs, the construction period cost multi objective optimization model was improved. In order to solve the problem of small search space and low accuracy in the optimization process of NSGA-Ⅱ algorithm, based on the introduction of dynamic crossover and mutation probability, an improved NSGA-Ⅱ algorithm for solving the model is designed. The algorithm is docked with the BIM5D platform to simulate the construction process and the capital and resource curve to improve the practice of single algorithm optimization. Case analysis shows that the improved NSGA-Ⅱ algorithm combined with BIM5D to solve the time cost optimization problem can effectively optimize the schedule and cost targets.
