基于相互作用网络的大型工程项目组织结构风险分析

为解决在工程项目管理中将组织和项目隔离的问题, 提出了大型工程项目系统的组织-任务相互作用网络模型. 在随机失效和故意攻击的条件下, 分别对随机型、集权型和金字塔型组织网络结构对项目工期的影响进行了解析和仿真分析. 研究结果表明: 只需攻击一定比例的组织节点即可导致整个网络完全瘫痪, 从而造成工期严重延误. 当组织中较少比例节点遭受故意攻击时, 项目工期将明显多于同样比例节点存在随机失效的情况. 以广州-珠海城际轨道交通工程项目为例, 构建了该项目的相互作用网络并对其组织节点面临随机失效和故意攻击的情况下进行了风险分析.

Interdependent network based risk analysis of organizational structures for large-scale engineering project

To overcome the shortage of treating the organizations and projects separately in the research of project management,we propose an organization-task interdependent network model for large-scale engineering project systems.The effects of organizational structures,e.g.,random structures,centralized structures and hierarchical structures are analyzed on project completion time.Results show that the project completion time is much higher than random failure when certain proportion of organizations is under targ...
