Research On Modeling And Managing Of Complex Product Development Process

One of the core competitions of the enterprise is development capability of new production, and higher standard is needed in the process of this sort of production developing because the process of itself is complex. It is hard to meet the demand of managing its developing by traditional developing model and management measures. The continuous improvements of information technology and management method at present time support the sustained improvement of production developing for enterprise. The study on the modeling and managing of the process in developing product has been carried out based on using modern management theory and technology,which.is meaningful for improving the enterprise competition, shorting the production period and reducing the costs.Firstly, the architecture for managing the process has been studied in this paper, based on deep analysis for the series of management issues in the process of complex production developing. And then integrated modeling, scope management, knowledge collecting and sharing in the production developing process are all studied deeply as well here. The three main sections are as follow: the complex production developing modeling framework, which is three-dimensional cube, was built, adopting the unifying integrated modeling thought. Tasks was planned by adaptive immune chaos genetic algorithm, based on the decoupling of design structure matrix. Paying attention to the problem of knowledge accumulating, sharing, the knowledge portal was adopted to help enterprise manage the dominant knowledge and recessive knowledge. Case study has been carried out as well which is about the developing process of the whole vehicle.The main work and innovation are as follows:1. The process management architecture has been proposed based on the PDCA process management improvement thought, analyzing its features and issues. On the basic data platform of the enterprise, the process controlling layer has been designed which contain four parts: business modeling platform, project management platform, designed data management platform and knowledge management platform. After that, auger-type improvement model of production development process management has been designed to optimize the management continually.2. Business modeling in complex production developing process has been studied and the integrated model framework of complex production modeling was designed, including developing process dimension, work flow dimension and organization method dimension. Integrated complex production model can improve the model consistency remarkably, create organic correlation between models and improve the describe ability of the enterprise model, so that it can reflect the features of the enterprise system which is unavailable by several independent views. Based on modeling through three dimensions, applying the top-down layered refinement of decomposition thought, making each work detailed from high level, the detail description for the specific business process was carried out.3. The scope management, task decoupled and scheduled and so on in complex production developed process were studied. Firstly, the WBS method of the developing task was built, considering the function and logical relation of each task, and the information of human finished the task, the organization and the resources. The coupled tasks was decoupled by the decomposition algorithm process and lacerate the algorithm process based on DSM. At last, based on the genetic algorithm propose a adaptive immune chaos genetic algorithm,and the algorithm have been applied to the schedule of the production developed process.4. The research of the knowledge portal system of complex product development process was performed. The knowledge management process were built to support complex product development,and the knowledge portal system architecture including six core function modules were proposed,using the B/S model which composed by data storage layer, function layer, application layer and presentation layer. Knowledge portal system provides a unified support platform that can effectively strengthen the internal communication between researchers, information, systems and business processes to enhance the efficiency of complex products development.5. A case study of vehicle product development was implemented on the modeling and management of complex product development. The WBS of the vehicle product development process was built, based on the decoupling research of coupled tasks. Using microsoft's sharepoint platform, the knowledge portal system of research institute including document management, project meetings and task management, experience management, data management was designed and developed.
