Research Of Methods And Application On Multi-project Management Of Network Collaborative Design With Generalized Resource Constraint

In the discrete manufacturing industry transformation progress from cost advantages to technical advantages nowadays, it is essential to enhance the capability of independent development of components and parts industry rapidly, and build the capability of synchronized development with the machine factory, in order to improve the industrial chain cooperated with new product development efficiency. Concerning the common requirements of multi-project management of network collaborative design between mainframe factories and suppliers in the industrial chain, the author proposes the thesis of multi-project management theory in network collaborative design and application research with generalized resource constraint, by survey and demand analysis of large number of new product developments in companies.â‘ A network resource management model under generalized resource constraints for collaborative design is established. Generalized design resources formation features and type under manufacturing supply chain cluster model is summarized, generalized design resources and design resources pool is defined, the concept of particles of resources has been put forward innovative, the construction of generalized engineering resources pool and the characteristics of design resource particles and operational definition is finished. The generalized design resource demand management model for multi-task project plan and design resources is proposed to match the broad and dynamic re-match basis.â‘¡A constraint-based association and the Semantic Web's dynamic management model for collaborative design task is Proposed. The networked collaborative design patterns and characteristics under Supply chain cluster is summarized, a network-based classification of collaborative design task, the task associated with the dynamic binding mechanism and management model is established. Semantic Web-based collaborative design task description model for network co-design of the host companies, suppliers and computer can be a common understanding and recognition is proposed. Collaborative design task ontology defines the task content, task relevance, information flow and collaborative planning feature attributes describe the semantic metadata model for the network co-design multi-project task management, and knowledge management is built to achieve the foundation.â‘¢The author proposes models, methods and key technology of multi-project task/resource matching in network collaborative design, which are consisted of multi-project cooperated plan formation and resource'particle'constraint matching model, multi-project cooperated plan execution status monitoring, and dynamic re-matching method and key technology of plan and resource change. Constraint matching algorithm and examples of demand-pull type and resource derived type between the plan and resource'particle'has been created, in the circumstances of pre-plan included, pre-plan excluded, prior plan and emergent order insert status; algorithm and examples of real-time management and control realization, which focuses on launching, freezing, recovering, delay and completion in multi-project cooperated plan execution processes; dynamic re-matching algorithm and examples during plan and resource change or unexpected unbalance.â‘£Software development and application of network collaborative design platform. On the basis of multi-project management theory and key technology research, the author, being the core researcher, uses the UML modeling method, SOA, J2EE technical infrastructure and other methods to build the business model of'network collaborative design platform software'and N-level technical infrastructure. The author has also participated in the design and testing of'network collaborative design platform software'V2.5 edition, which was applied successfully in the collaborative design project management of 10 new cars in China Jialing Industrial Co., Ltd. (Group), Chongqing Jianshe Motorcycle Co., Ltd, Chongqing Lifan PCV Co., Ltd cooperated with other hundreds of suppliers, and it solves application engineering problems in multi-project cooperated management including multi-project cooperated plan formation, plan and resource matching, multi-project cooperated plan execution status monitoring, and confliction of plan and resources with distributed suppliers participated, and finally obtains remarkable achievements.
