摘要：

针对EPC模式下设计-采购-施工任务并行执行的多目标联合优化问题，构建基于z标记的多参量灰色图形评审技术模型。首先，借鉴计划评审技术网络的建模思路，构建由3个分别表示设计-采购-施工任务执行流程的子图形评审技术网络图构成的多参量灰色图形评审技术网络分析模型；然后，在探讨正常执行活动与返工执行活动的时间与费用、费用与质量之间函数关系的基础上，提出基于三元区间数形式表征输入参量与输出参量不确定性的并行执行时间、费用与质量的矩母函数构造方法；其次，在分析设计-采购-施工任务并行执行下多参量灰色图形评审技术网络各参量求解方法的基础上，给出了该网络关键性时间节点开始执行时间与总执行时长的求解方法；最后，依据EPC模式下建设项目需求，分别构造了基于进度导向型与质量导向型的多目标联合优化模型，并以某会议中心项目为例，验证了所构建模型的有效性。研究成果为评估EPC模式下设计-采购-施工任务在并行执行过程中的进度、费用与质量目标的达成情况提供了科学的定量化分析方法，同时也为EPC模式在中国情景下的推广奠定了理论基础。

Abstract:

In order to solve the multi-objective joint optimization problem of engineering-procurement-construction task concurrent execution in EPC mode, a multi-parameter grey graph review technology model based on Z tags is constructed. First, a multi-parameter grey graph review technical network analysis model is constructed, which is composed of three sub-graphical evaluation review technique network graphs representing the engineering-procurement-construction task execution process respectively. Next, based on the discussion of the functional relationships between the time and cost of normal execution and rework execution, as well as the cost and quality, a moment generating function construction method of concurrent execution time, cost and quality is proposed based on the ternary interval number form to characterize the uncertainty of input parameters and output parameters. Afterwards, based on the analysis of the solving methods of various parameters of the multi-parameter grey graph review technology network under the concurrent execution of engineering-procurement-construction tasks, the solving methods of the start execution time and the total execution time of the key time nodes of the network are given. Finally, according to the requirements of construction projects in the EPC mode, the progress oriented and quality oriented multi-objective joint optimization models are constructed respectively, and a conference center project is taken as an example to verify the effectiveness of the constructed models. The research results provide a scientific quantitative analysis method for evaluating the progress, cost and quality objectives of engineering-procurement-construction tasks in the concurrent execution process in the EPC mode, and lay a theoretical foundation for the promotion of EPC mode in China.

Key words: engineering-procurement-construction task, concurrent execution, multi-parameter grey graphical evaluation review technique network, multi-objective joint optimization
