摘　　要：如何针对多主体下合同项目延误与项目群误期损害费用之间的非线性关系,优化并控制NCRPE约束下项目群误期损害费用是业主关注的问题。本研究首先从理论与实践两个角度分析了多主体下项目群误期损害费用计算结果的不足;其次分析了NCRPE约束下项目群误期损害费用的非线性特点;再次构建了项目群实施前第一阶段NCRPE均衡优化模型;最后采用离散马尔可夫过程来刻画项目群中合同项目的状态并据此计算项目群误期损害费用非线性概率,以因合同项目随机性使项目群误期损害费用最小化为优化目标,构建了项目群实施过程中第二阶段项目群误期损害费用非线性优化模型并说明了不同情境下的求解方法。研究结果表明,项目群误期损害费用非线性优化效果要优于线性优化效果,构建的模型在现行规则下,能有效地降低因合同项目随机性给业主造成的误期损害费用。研究成果为开展多主体下项目群误期损害费用优化、制定相应的项目群误期损害费用管理规则提供了依据。The optimization and management of delay damages in project clusters,particularly under the constraints of Non-contractual Risk Participation Equilibrium(NCRPE),represent a significant concern for project owners.The issue is especially pertinent given the nonlinear relationship that exists between contract project delays and the collective overdue damage costs incurred by multiple stakeholders.Firstly,the study initially delves into the theoretical and practical dimensions of the deficiencies inherent in calculating collective overdue damage costs within multifaceted stakeholder environments.Subsequently,it explores the intricate nonlinear characteristics of these costs under the constraints imposed by NCRPE.An equilibrium optimization model is then developed for the initial phase of NCRPE prior to the implementation of project clusters.A discrete Markov process has been utilized to characterize the states of contract projects within the cluster and compute the nonlinear probabilities associated with collective overdue damage costs.The objective of this study is to minimize costs arising from contractual uncertainties by formulating a sophisticated second-phase nonlinear optimization model that addresses collective overdue damage expenditures throughout the project execution phase.This endeavor will also delineate solution methodologies that are adaptable across diverse scenarios.The research findings indicate that nonlinear optimization yields superior outcomes in comparison to linear methodologies,particularly with regard to the cumulative costs associated with overdue damages.The proposed model effectively mitigates the delay damages incurred by owners due to contractual uncertainties under current regulations.These results provide a foundation for optimizing collective overdue damage expenses within multi-stakeholder contexts and formulating corresponding management guidelines pertaining to such expenses.
