Cooperative Project Management Research For Housing Construction

A housing construction project (HCP) consists of several project phases with different involved organizations, it is difficult to control effectively by the owner of house, and its information sharing and cooperation among organizations are inefficient, so a kind of effective project management system is in dire need. Based on the demand, the study is focused on the research of Integrated Project Management (IPM) and of Cooperative Project Management (CPM), as a result the housing construction could be completed effectively by Lifecycle Project Management (LPM) for house owners and cooperative work between involved organizations.Due to myriad source and complex management for project data, data model of project management system is studied with ontology, main concepts and relations are introduced, then project public domain and project private domain are discussed for IPM. Based on the data model, system database is designedTo the demand of IPM and CPM, the system is designed into two subsystem: 1) IPM subsystem based on C/S, which supports LPM in practice and supports IPM among different projects and information sharing with enterprise systems in range, 2) CPM subsystem based on B/S, which use web-based technology and network computer technology to help manage project execution and enhance cooperation energy. Then system architecture is analyzed and detailed, and class framework is presented. Lastly to the engineering problem such as time calculation, resource optimization and data management, optimum solution is designed, and the algorithm for generating prior sequence based on common path are originally presented.Based on our system, project plan, IMP and CPM of Housing Construction can be supported well, and its efficiency is improved. At last the trend of the system development is conceived.
