Design And Implementation Of Interactive Workflow Simulation System

Workflow is the calculation model of the work process. At present, many workflow products on the market do not support the simulation of the workflow model.The main emphasis of Process management Oriented Software Production Line, which is the Sub-topics of the state high-tech research and development plans(863 plans) named high credibility of software tools and integrated environments,is Process Simulation Tools.Based on this Sub-topics, the paper puts forward the Interactive Workflow Simulation System.The main contents of the paper are as follows:1. A study is made on the development and the current simulation situation of workflow. This paper makes an overview of the current features of workflow products, introduces in detail the characteristics of two kinds of domestic workflow simulation products and three ways of implementing the workflow simulation.2. An introduction is made on the basic concepts of workflow and the relevant principles of workflow model, and a focus on Extended Xinpai driven workflow mode based on Petri net.3. Usually, workflow simulation systems make verifications of the workflow model on semantic-level (dynamic simulation). The workflow simulation system mentioned in this paper, making verifications seamlessly on syntax level (model static checking) and semantic-level (model dynamic simulation), makes a higher credibility of the simulation system. According to the concrete business, users input the global variable values(related datas) by hand. Based on this set of data, event generator generates events to drive the transfer process down. The interface, used for inputting data, is the main interaction, where users and system interact with each other. The users receive feedback from the interface in time so as to achieve an effective interaction.4. Based on the principles and related technologies of the interactive simulation system, the design of the interactive simulation system of B/S structure is achieved.
