Research On Key Technologies Of Conflict Coordination And Resolution In Customer Collaborative Product Innovation

In recent years, global market competition is increasingly fierce for manufacturing enterprises, and product upgrading has been accelerated. Meanwhile, customer demand has hold characteristic of complex, dynamical and individual, which puts forward higher requirements for manufacturing enterprises. Therefore, improving the ability of product innovation and speed of launching new products to market has become an important way of enhancing competitive advantage for enterprises. Customer Collaborative Product Innovation (CCPI), as a new product design mode, can help companies improve their product innovation capability. Hence, it has attracted more and more attention from business and academia. However, the diversity of innovation agents, the complexity of innovation activities, and the dynamic interaction between innovation agents make innovation process with various conflicts, leading to CCPI process coordination and management difficult. Therefore, on the basis of researching the latest theoretical achievements about customer collaborative innovation, process coordination and conflict resolution methods of collaborative design at home and abroad, from the views of collaborative agent, collaborative design optimization and resource, the key technologies of conflict coordination and resolution of CCPI are focused on. The main contents of the thesis consist of the following parts.Firstly, the theory framework of CCPI conflict coordination and resolution is proposed. The main basis supporting theories of CCPI conflict coordination and resolution are summarized, including customer innovation theory, collaborative design process coordination theory, and conflict resolution theory. In order to effectively identify customers with strong creative ability from large number of customers and actuate them to participate in the process of collaborative product innovation, customer knowledge contribution measurement model based on fuzzy AHP and Shapley is proposed. Subsequently, the process and characteristics of CCPI are analyzed. Combined with these characteristics, CCPI performance influencing factor set is established. Furthermore, fuzzy cluster analysis method based on fuzzy equivalence relation is put forward to identify the critical factors. Aiming at these critical influencing factor, CCPI conflict coordination and resolution working model is constructed, several key technologies of CCPI conflict coordination and resolution are summarized.Secondly, multi-agent conflict coordination technology of CCPI is studied. From the perspective of system science, the complexity of CCPI system is analyzed and CCPI innovation agent stimulus-response model is proposed. Further, the behavior of agents and the origin causing conflicts between agents are analyzed. In order to coordinate preference conflict on design goal among the agents, two-tuple linguistic analysis is used to integrate the agents'evaluation information with multi-granularity. Taking satisfaction as design evaluation criteria, a multi-agent coordination model, which aims at maximizing the satisfaction degree of agents, is established. Then, a dynamic adaptive particle swarm optimization algorithm of the coordination model is proposed to enhance the optimization efficiency of product design.Thirdly, a conflict resolution technology based on hierarchical knowledge matching is put forward. To converse the customer requirements into product function structure, a customer requirement mapping method based on QFD and"function - principles - behavior-structure"is proposed. Further, conflict resolution process model of CCPI is established and hierarchical knowledge matching-based conflict resolution flow is presented. To enhance the conflict resolution efficiency, the method of conflict reduction and critical conflict identification based on rough set theory is brought forward. Then, based on the mapping relation between conflict - function - parts, by the sequence gradation of product- component- bottom component-part, hierarchical knowledge matching-based conflict resolution method and knowledge matching optimization algorithm based on an improved tabu search are proposed.Subsequently, resource concurrent access conflict resolution of CCPI prototype system is studied. Based on CCPI work principle, network topology framework and concurrency control model of the system are constructed, concurrent conflict detection and control flow is presented as well. Then, in order to improve concurrent access performance of the system, a new concurrent access pattern called Merged Request is proposed, and the pattern solution algorithm based on Java multithread synchronization and locking mechanism is discussed.Finally, a CCPI Prototype System (CCPIPS) is developed. The system structure framework and function modules are described. Furthermore, using the tools of collaborative design and conflict resolution in CCPIPS, a motorcycle parts design optimization is implemented to illustrate the feasibility and effectiveness of the proposed theoretical results.
