摘　　要：项目管理规划是保障输变电工程项目时间成本管控的核心要素之一。针对多输变电工程项目协同管理规划,考虑输变电工程特点,对已有关键链方法进行改进,提出更适合于输变电工程不确定特征的缓冲期计算方法。综合考虑各施工活动中时间协调关系、资源协调关系、每日和整体资源约束,建立多输变电工程项目的成本—时间多目标优化模型,采用改进磷虾群算法优化计算帕累托最优解集合。结合算例仿真结果和算法分析证明模型和算法的有效性,并采用灵敏度分析法分别分析影响总工期和总成本的关键施工资源及其组合。Project management planning is one of the core elements to ensure the time and cost control of power transmission and transformation projects.In view of the collaborative management planning of multiple transmission and transformation projects,this paper considers the characteristics of transmission and transformation projects to improve the existing critical chain methods,by proposing a new buffer period calculation method.Then,establishes cost-time multi-objective optimization model by comprehensively considering the time coordination relationship,resource coordination relationship,daily and overall resource constraints in each construction activity,uses krill swarm algorithm to calculate Pareto optimal solution set.Finally,the simulation results proves the effectiveness of the model and the algorithm,and the sensitivity analysis provides the key construction resources and their combinations that affect the total construction period and total cost.
