Reasearch On The Cooperative Quality Control Strategy Of Manufacturing Network

With the tendency of globalization and fierce market competition, manufacturing network is founded by core enterprise associates with other around enterprises according to certain rules and methods. The quality control of manufacturing network is different from that of the traditional enterprise, and it becomes one of the important condition for manufacturing network's smooth operation. In this paper, the author reseached the cooperative quality control strategy of manufacturing network, the contents of this paper is summarized as follows:1) Described the definition, formation, format and characteristics of manufacturing network, summarized the development and state-of-art related to manufacturing network quality control, discussed the achievement of cooperative quality control and quality process control, after that, the cooperative quality control of manufacturing network is proposed as the main contents of this article.2) Discussed the collaborative quality control environment and the quality transfer processes of manufacturing network with the concept of quality chain, established the model of cooperative quality control of manufacturing network which is based on three dimension of quality process, member networks and quality information, the control schema is proposed and the specific quality control strategy of each dimension is studied.3) Based on the analysis of characteristics for quality process in manufacturing network, researched the inter-organizational quality control process integration management and collaboration issues of manufacturing network with workflow and multi-agent technologies, use WF-Net for the extended quality control process workflow modeling, established the model of Quality Control Process Workflow Managed by Agents (QCPWMA), discussed the multi-agent structure, configuration and operation of the model, established the coordination method of inter-organizational quality control process based on the Synchronous Point (SP) and its implementation in QCPWMA model.4) Discussed the quality risk control issues in collaboration of manufacturing network with game theory, Statistics and Neyman-Pearson theory, established a risk control model which contends multi-variable factors, then applyed this model to the quality risk control processes using different cooperation method and quality inspection strategy for f manufacturing network enterprises, calculated the optimal solution of sample selection strategy for achieving min quality risk, compared of quality risk under different control mode and extended this model to the multi enterprise application environments5) Researched the cooperative quality control performance evaluation methods of manufacturing network, established the enterprise collaboration degree evaluation index system and evaluation model based on quality information coupling, and established the enterprise quality control performance evaluation index system, described the quality control performance evaluation with fuzzy comprehensive evaluation method .6) The proposed theories and methods have been realized and verified partially in the project of manufacturing network management, which is cooperatively conducted by Tianjin University and Weichai Power Co., Ltd.
