Research On The Agent-based Construction Project Integrated Management Model Under Complexity Theory

Along with the trend of the construction project complexity, there is inadequacyfor traditional theory and model of project management to understanding of theconstruction project complexity. Therefore, there is urgent need to the new ideas, newtools and new technology of construction project management. The vigorousdevelopment of the complex adaptive system theory and the mechanism of emergenceprovide new ideas for the research on the complex construction project management.The combination between agent-based complex system modeling and the projectmanagement theory including project management maturity model provides effectiveway for study on the complex construction project integrated management. Based onproject management maturity theory, complex adaptive system theory and mechanismof emergence, many research methods including structural equation model,agent-based complex system modeling and possibility theory are used in thisdissertation, which is order for some deep fundamental research on the complexconstruction system modeling, measurement, and whole-element, whole-processintegrated management. This is not only perfect the theory system of projectmanagement, but also provide concrete methods for the practice of complexconstruction project management, which has certain practical significance.The main work and innovation points of this dissertation as follows:First, based on the review of project complexity literature and the research of theconcept and structure of project complexity, the Construction System ComplexityConcept Model (CSCCM) is built, considering the characters of construction project.In this dissertation, the behavior of the construction system is described in six anglesof view, including engineering technology, project stakeholders’ organization structure,engineering task, engineering information, project objectives and project environment.Second, based on the Construction System Complexity Concept Model (CSCCM),Construction System Complexity Measurement Model (CSCMM) is built. Themeasurement indicators are determined after the literature review. And structuralequation model is used for the data analysis and model fitting during the measurementof construction project system complexity.Third, the Agent-based complexity system modeling is introduced into theresearch on construction project management. The basic agent prototypes are developed and the structure of agent prototypes is designed aiming at characteristicsof the construction project. The agent prototype is determined and described throughthe conditions set and the results set. The CPM3-based agent prototype is developedcombined with the construction project management maturity model based on fuzzycomprehensive evaluation.Fourth, the modeling method of master-slave agent is developed aiming at thepossible coordination optimization problem under resource restraints during theprocess of agent-based modeling. The multi-agent interactive technology frameworkis elaborated in detail in this dissertation. After that, the construction projectmanagement maturity model is introduced into the framework as the intelligentreasoning method. The CPM3-based multi-agent interactive framework is developed.Fifth, the master-slave based multi-agent interactive technology framework isused in the empirical research on the classical project management maturitycontinuous improvement problem, establishing the project management maturitycontinual improvement multi-agent interactive simulation model under resourcerestraints. Upper-side and down-side nearness is put up based on fuzzy theory, and isused to measure the matching of strategy equilibrium. A crisp transformation isimplemented based on possibility theory. Genetic algorithm is presented to solve themodel, through development of Path Relinking (PR), which get the better solution.
