Study On The Integrated Management For Construction Project

Construction projects are open complex systems,management of which will exert great impacts on the national economy and on the benefits of the investor and the project participants.However,the management tools of different phases are isolated during traditional management of construction project.A lot of potential disadvantages are caused,such as end user's requirements not be satisfied from the inception;difficult to manage the interfaces among different phases;the knowledge and experience owned by different participants not serve for the realization of the construction project objectives, etc..In order to solve these problems,the guiding ideology of the management is gradually changed from division of labor to the integrated management.The paper tries making research into the integrated management of construction project to overcome the malpractice of traditional management of construction project.Major achievements of this thesis are as follows:(1) Based on the integrated management theory and the project management theory,new ideas for the integrated management of the construction project are proposed and its conceptual model is established according to the characteristics of construction project in this paper.The model contains two layers of meanings.On the one hand,as viewed from the various phases of construction project the corresponding beam of the integrated management is selected and mapped in each phase to carry out the integrated management according to the characteristics of each phase.In project decision phase,the life cycle integrated management of construction project is carried on by using the Life Cycle Cost Analysis and the Life Cycle Quality Analysis.In project design and planning phase,the Quality Function Deployment(QFD) method is improved and used in the integrated management of the project stakeholders' requirements.In building phase,the Genetic Algorithm(GA) method is used to realize the tradeoff of the quality,schedule and cost of construction project.In ending phase,the theory and methods of Knowledge Management are used to integrate the technology resource accumulated during the whole process of construction project.On the other hand,from perspective of the entire process of construction project,the bilevel decision-making mechanism composed of the owner and the participants in different phase is proposed and used in the whole process integrated management of the construction project.The research provides a clear concept frame for the project staffto carry on the integrated management of construction project.(2) According to the characteristics of the construction project,this paper sets up the improved house of quality(HOQ) model that is suitable for the integrated management of construction project stakeholders on the guidance of the Quality Function Deployment(QFD) theory,and puts forward the operational mode of integrated management for stakeholders and its program.The improved QFD method can improve the satisfactory degree of the construction project stakeholders and guarantee the project going on successfully by integrating the project stakeholders' requirements and translating them into the process of the construction project implementing.(3) The paper builds up the conceptual model of the whole process integrated management of the construction project according to its characteristics,based on which the bi-level programming model of the whole process integrated management of construction project is established according to the optimization theory of the bi-level system,and the corresponding solution procedure is proposed.The process of solving the bi-level programming model can coordinate the partial goals of the various phases and the entire objective of the whole process of construction project.To verify and demonstrate how the model works,the model is used in the problem of project duration coordination decision-making between the project owner and the contractor in construction project.A numerical study showed that the model can help to actualize optimization of project duration coordination and Pareto improvement of revenue for two parties in the contract on condition that the project owner expects the contractor to actively compress project duration furthest by supporting revenue incentive measures instead of traditional direct instructions.The achievements of this study enrich the project management theories and have important value for construction practice.
