    摘要:

    针对现有文献中较少考虑交互依赖关系对项目组合动态选择影响的问题,借鉴复杂网络理论,提出项目交互耦合网络概念,并从项目收益、资源成本、项目风险、项目状态、交互依赖关系及战略匹配程度等6个方面描述网络演化的影响要素.在此基础上,提出网络生成及调整规则,给出网络稳定状态定义,建立项目交互耦合网络.研究结果表明,与传统模型相比,项目交互耦合网络模型能得到更优的项目组合,能更有效地利用资源,规避风险,提高收益,同时,项目交互耦合网络能更好地了解项目结构,为项目组合管理提供支持.项目组合管理者应对那些节点介数大、聚集系数高的项目即核心项目进行重点扶持与保护,以防这些项目失败后引起其邻节点失败,甚至导致整个项目网络发生级联失败.

    Abstract:

    Since few studies consider the influence of interaction on the project portfolio dynamic selection, the conception of project interactive coupling networks is proposed based on the complex network theory with interaction effect. The definition is described from six aspects, which are project profit, cost, risk, states, interactions and strategy fit. Then based on this, we propose generation and adjustment rules of the network, define the stable state and develop this network. The research shows that compared with the traditional optimization model, the portfolio got from the project interactive coupling network is better. It can use resources more efficient, avoid risks and increase benefits. Moreover, the project interactive coupling network can be understood better, which can give some support to project portfolio management. Project portfolio managers should protect and support the projects with high betweenness centrality and clustering coefficient, which are the core projects in a portfolio, in case the failure of these projects will lead to failures of their neighbour nodes or even a cascading failure of the project network.
