【Abstract】 In order to better help the workshop managers handle and control production systems operation in real time, the research on lean operation dashboard for workshop management of discrete production systems was put forward. The lean operation dashboard combined with requirements that lean production principle asked for the workshop production system operation. The research aims to assist workshop managers to effectively grasp the performance of production process and dynamicly monitor the implementation of production plan in real time.In chapter 1, the dissertation research background was elaborated. Firstly the research situations were reviewed and summarized about discrete production systems. Then shortcomings and weak fields of present related studies were found out so that some work must be done to solve above questions. And the research threads and contents of this dissertation were given after explaining signification of the dissertation research and analyzing status of relevant research papers. Finally the overall organization framework of the whole dissertation research contents was described at the end of this chapter.In chapter 2, the operation principle and system architecture were put forward about workshop production systems lean dashboard. The evaluation index system of lean workshop was built combined the characteristics and requirements of lean production mode. The presentation background of workshop production systems lean dashboard was discussed. The definition and function requirement were given for the workshop production systems lean dashboard. The conception model of workshop production system lean dashboard was proposed on the basis of analyzing workshop production system operation process. In the end, the working principle and the system architecture of workshop production systems lean dashboard were brought forward.In chapter 3, the design and calculation were studied about the digital display control parameters of the lean operation dashboard. Firstly the digital control parameters system was built based on lean workshop appraisal index system. The principle and basis were elaborated for selecting the dashboard control parameters. The contents were designed about dashboard control parameters. Then the collection was analyzed about the workstation manufacturing data. The formula of each dashboard control parameter was given. Finally the relevancy between the parameters and the manufacturing factors was analyzed.In chapter 4, the lean operation model and its solving algorithm were studied for the workshop production system. Firstly workshop production system lean operation based on process stability was analyzed. Then the general format of multi-objective planning question of large-scale systems was refered to. And it is put forward that the problem of production system lean operation can be abstracted to multi-objective planning question of large-scale systems. The specific model of workshop production system lean operation was built with workstation manufacturing data as a decision-making variable and all the control parameters as dynamic constraints in dashboard digital display control parameters system. Finally the ’harmonizing cluster results’algorithm for solving the model was found out to resolve the difficulties of dynamic, multi-objective and multi-stage features of the lean operation of production systems. The reachable domain of the initial target value was analyzed and the up to and the methods and steps of the model solution algorithm were given. The model and its solution algorithm are applied to an assembly line. The application results showed that the model is reasonable and its solution algorithm is available.In chapter 5, the whole research in this dissertation and prospects for future research work were summarized.更多还原
