IPD模式下努力因素对利益分配机制的影响

Efforts to influence the distribution of interests in IPD

Integrated Project Delivery(简称IPD)即项目集成交付模式,是一种新型的交付模式,核心是利益分配机制.目前,中国对IPD模式利益分配机制的研究忽略了建设过程中项目各方努力程度与项目成功的关联,并在利益分配中忽视了努力行为,促使项目各方忽视努力成本的投入而确保自身收益,导致项目工程变更增加、风险提升、项目失败.为改善此现象,通过对项目各方努力行为的研究,列举出十六项工程建设中的努力行为,依此建立努力系数.结合重要系数、风险系数等建立新的Shapley法的利益分配模型,通过算例分析研究表明:该模型有助于各参与方积极进行项目建设,从而提升各参与方的收益.

Integrated Project Delivery(IPD)is a new kind of delivery mode.IPD model is the core of interest distribution mechanism.The IPD mode of interests distribution mechanism separates relation of participants in the process of the construction effort and success of the project.Based on the research of the participants,16 items of the behavior of efforts in the construction of engineering are enumerated and effort coefficient by combining the important coefficient,and risk coefficient a new profit distribution model of Shapley method is set up.Through example analysis,the model can help the parties actively for project construction and the promotion of the benefits of the parties.
