Abstract

Non-commercial resources provided by employers (NCRPE) are the imperative factors affecting the progress of engineering projects. However, the NCRPE with limited supply ability is rarely considered in the schedule optimization models in previous studies. The NCRPE schedule requirement may exceed its limitation, resulting in failing to optimize the schedule. Therefore, a new schedule optimization model is built from the perspective of NCRPE. First, the features of NCRPE and corresponding optimization theory are analyzed. Then, two optimization models are proposed in multi-contract environment before and during the construction of a project, aiming to minimize the unbalance coefficient, variance of NCRPE, and the requirement strength of NCRPE, respectively. Finally, a case study about the South-North Water Transfer Project Program X is conducted. The results show that the proposed model could effectively solve the NCRPE schedule optimization problem. A reasonable and practical program planning and adjustment within different stakeholders can be obtained. The NCRPE schedule optimization can minimize the peak demand amount of the program resources and achieve a relatively balanced total resource demand before the program implementation. Besides, it ensures that the original production system capacity can satisfy the actual demand in the program implementation. The research results can provide a basis for the bidding of each contracted project in the program and the resources optimization of each contracted project in the program implementation process.

大型项目项目业主提供的进度非商业资源优化模型

摘要

雇主提供的非商业资源(NCRPE)是影响工程项目进度的重要因素。然而,以往研究的进度优化模型中很少考虑供应能力有限的 NCRPE。NCRPE 进度要求可能会超出其限制,导致无法优化进度。因此,从 NCRPE 的角度构建了一个新的进度优化模型。首先分析了NCRPE的特点和相应的优化理论。然后,在项目建设前和建设过程中,提出了多合同环境下的两个优化模型,旨在分别最小化不平衡系数、NCRPE的方差和NCRPE的需求强度。最后,对南水北调项目 X 进行了案例研究。结果表明,所提出的模型可以有效地解决 NCRPE 调度优化问题。在不同的利益相关者之间可以获得合理实用的方案规划和调整。NCRPE调度优化可以最大限度地减少项目资源的峰值需求量,在项目实施前实现​​资源总需求的相对平衡。并且保证了原有的生产系统能力能够满足方案实施中的实际需求。研究成果可为方案中各签约项目的招标及方案实施过程中各签约项目的资源优化提供依据。在不同的利益相关者之间可以获得合理实用的方案规划和调整。NCRPE调度优化可以最大限度地减少项目资源的峰值需求量,在项目实施前实现​​资源总需求的相对平衡。并且保证了原有的生产系统能力能够满足方案实施中的实际需求。研究成果可为方案中各签约项目的招标及方案实施过程中各签约项目的资源优化提供依据。在不同的利益相关者之间可以获得合理实用的方案规划和调整。NCRPE调度优化可以最大限度地减少项目资源的峰值需求量,在项目实施前实现​​资源总需求的相对平衡。并且保证了原有的生产系统能力能够满足方案实施中的实际需求。研究成果可为方案中各签约项目的招标及方案实施过程中各签约项目的资源优化提供依据。NCRPE调度优化可以最大限度地减少项目资源的峰值需求量,在项目实施前实现​​资源总需求的相对平衡。并且保证了原有的生产系统能力能够满足方案实施中的实际需求。研究成果可为方案中各签约项目的招标及方案实施过程中各签约项目的资源优化提供依据。NCRPE调度优化可以最大限度地减少项目资源的峰值需求量,在项目实施前实现​​资源总需求的相对平衡。并且保证了原有的生产系统能力能够满足方案实施中的实际需求。研究成果可为方案中各签约项目的招标及方案实施过程中各签约项目的资源优化提供依据。
