大型建筑工程项目多类型资源的有效配置,是现阶段项目管理理论与工程管理实践面临的关键问题,特别是在考虑工艺顺序和间歇时间的工作可操作性特点,以及多资源之间反馈影响的情况下。通过整合挣值法和系统动力学理论,在分析资源可用性和工作可操作性之间因果关系的基础上,本文构建了大型建筑工程项目多资源配置的系统动力学模型。以上海市重大工程投资统计数据作为模型参数依据,模型的仿真结果表明:建筑工程项目不同类型资源其配置重要性与系统影响性存在显著差异,在制定资源配置策略时应同时考虑项目运作方式的特征与多资源之间的匹配,资源不匹配则容易导致资源配置系统失去稳态或策略失效。这为进一步研究项目管理中多资源配置提供了理论参考和实践支持。
The efficient allocation of different types of resources in large-scale construction projects is a key issue that the project management theory and practice facing nowadays. Especially both the work operability, which including the process sequences and time interval, and the feedback impact of these resources are considered. Combining the earned value method and the system dynamics theory, this paper establishes a system dynamics model of multiple resource allocation of large-scale construction projects. The modeling is based on the causal analysis between the resource availability and the work operability. Major investment construction projects statistical data in Shanghai are used to set the model parameters. The simulation results indicate that there is significant difference on the allocation importance and systematically affect of different resources in construction projects. Both the project operation model and multiple resource matching should be considered when resource allocation strategies are developed. Mismatch of resources always result in unsteady of the resource allocation system or strategy failure. This research will provide theoretical reference and practice support to the further research on multiple resource allocation of project management.
