大型复杂项目的空间网络结构及其特征研究

Space-grid structure and characteristics of large-scale complex project

大型复杂项目的网络不是多个子网的简单叠加,而是分层的空间结构。本文运用复杂网络理论和方法,构造了大型复杂项目空间网络结构的三元组模型,并定义了空间网络的联接运算与收缩运算;然后对子项目关联系数、子项目关键度指数、活动关键度指数及求解算法进行研究,由此可以从项目层次、子项目层次和活动层次分析大型复杂项目的空间网络结构特征,并提出针对性的管理策略。案例研究表明,本文提出的空间网络结构及网络运算可准确描述大型复杂项目的网络结构,同时通过分析网络特征可提出有效的项目管理策略。

The network of large - scale complex project is not a simple supeIposition of sub - networks, but a hierarchical space - grid structure. Based on the theory and method of complex networks, this paper constructs the triple model of the network of large - scale complex project, defines the link operation and contract operation of the space - grid networks, and then investigates the correlation coefficient, the criticality indexes of subproject, the criticality indexes of activity and the solution algorithm. Based on these results, we can analyze the features of large - scale complex project from the project level, subproject level and activity level and propose the targeted management strategies. Our case study suggests that the space - grid structure and networks opera- tion can precisely describe the structure of large - scale complex project and we can propose effective project management strategy as well by analyzing the features of space - grid structure.
