有竞争的多项目并行柔性协作计划与调度模型研究

Research on a Model of Multi-Project Parallel Scheduling with Flexible Competitive Collaboration Planning

摘要: 针对多项目管理中资源冲突的问题，本文提出以项目总成本最小和多项目工期最短为目标，任务可任意拆分外包，且有多个协作伙伴竞争的多项目并行柔性协作计划与调度模型；改进了NSGA-II算法求解模型，采用了包含任务协作比例、协作伙伴和优先级的三维染色体编码方案标识任务属性。通过工程实例验证，证明了模型的实用性和算法的有效性，该优化方法能够有效协调项目间资源分配，提高企业多项目管理效率。

Abstract: To solve the resource conflict in the process of implementation of the multi-project management, a model of multi-project parallel scheduling with flexible competitive collaboration planning in which tasks can be outsourced arbitrarily and be competed among multiple partners was proposed to minimize the total cost of the projects and the duration of each project. According to the characteristic of the problem, this paper designed an improved NSGA-II algorithm for the sched-uling model, including the three-dimensional chromosome encoding scheme to identify the at-tributes of collaboration ratio, partners and priorities. With the practice project confirmation, the practicality of this model and the validity of this algorithm are verified. The optimization method can effectively coordinate the resource allocation among projects and improve the efficiency of multi project management as well.
