On The Fresh Product Operation Process Management In Chain Supermarket Based On Workflow For The Degree Of Doctor Of Philosophy In Engineering

The operation of fresh product is one of the most important and difficult part in chain supermarket. How to break the neck-bottle of the process management and optimize process management is significant to the industrialized operation of chain supermarket. Workflow management system provides a mechanism which integrates logistics, information flow, capital flow and corresponded processes and application. Therefore the integration, automation and management of business process in enterprises can be implemented. This dissertation studies the management system of fresh product operation process based on workflow in the aspects including workflow modeling based on Petri net, architecture of workflow management system, scheduling of workflow engine and integration of enterprise application systems, and realizes the optimization of process, perfect of architecture and integration of process in the operation of fresh product.In this dissertation, connected with the present situation and background of emergence, development and application of workflow management, the terms of workflow management and the standards proposed by WfMC are introduced, the application of workflow management as independent software is analyzed, and the development of trend of workflow management is explored. On the other hand, the theory of workflow modeling is defined systematically. The characteristics and expansion of Petri net and the methods of workflow modeling based on Petri net are studied in-depth. The validity of modeling is analyzed by Petri net.The characteristics of fresh product and the defects in the operation process are analyzed, and the methods of improving process management are proposed in the aspects including provider management, purchasing, distributing and local management. Then Petri net is applied in the workflow modeling to optimize fresh product process.To deal with the tasks ranking issue with fuzzy characteristics in fresh product operation process of chain supermarket, a scheduling model integrated with fuzzy planners is proposed. This model supports the ranking of tasks with fuzzy characteristics. According to the characteristics of workflow tasks, it gets the priority ranks of tasks by fuzzy analytic hierarchy, and causes the tasks series concerned with scheduling. Based on constructing a characteristics system of tasks, the tasks ranking with fuzzy characteristics are implemented in reason by FAHP. Consequently the scheduling is more scientific and the service of workflow management system is improved obviously.To deal with the issue of manual and semi-automatic tasks assignment in the process of fresh product operation, a strategy supporting load balance and experience value for task assignment of workflow is proposed and simulated and applied in the tasks assignment of operators in chain supermarket. On the basis of predicting the load of task actors, the strategy bridges the gap between abstract roles and real task actors, takes the following factors into account: the demand of tasks, the load of task actors, the performance and interest of accepting different categories of tasks, and forms a set of candidates by dynamic reassembling. In the implementation of the strategy, according to the prediction of load deviation, the load of task actors is divided into several sets,the tasks is assigned to the actor who has the highest experiential value in light load set.Assignment of tasks can be well implemented with the strategy, simultaneously the goals of load balance and considering of experience value can be achieved. The efficiency of role-based workflow management system is improved to a great extent with the strategy. A model of workflow management architecture based on Web service is proposed. This model defines the format of information, data transmission, describing of service, publishing and locating of service. It also integrates heterogeneous components and legacy systems, has friendly and consistent interface, and can be applied in distributed and heterogeneous environment.A frame of integration of application systems based on workflow management in chain supermarket is proposed. By the analysis of the integration techniques and application systems in chain supermarket, workflow management based on Web service is applied in the integration of application systems in chain supermarket, and satisfies the demand of all kinds of processes (including fresh product) management and expansion of chain supermarket.At the end, the entire dissertation is concluded and the future research is described.
