The E-government Workflow Cooperation Research Based On Workflow Modeling

As one of the greatest invention of the 20th century, Computer changed each field of living thoroughly, people's habit and the way of thinking was changed gradually by this transformation. E-commerce facilitated the development of current commerce enormously. As the greatest owner and user of resource, government was required to introduce information technology urgently in order to improve both working efficiency and service quality. E-government emerges as the times require under this background.The E-Government building of our country had great development in last years, which facilitated the improvement of working efficiency and service quality of all levels government wonderfully. But because of bureaucracy organization structure in our country induced the division of area and department badly, each one gone his own way as item build main body, which formed a great deal information island alone, and brought prodigious difficulty to the cooperate E-Government.In order to realize the cooperation of government affair, the zero gap connection among each using system should be guaranteed. But because of the limit of prophase build, the compatibility between existing systems of each department does not good. There are two ways to solve the problem: standardization rebuilding all systems, or finishing the connection among each system from software. Obviously the former can solve this question drastically, but can't realize easily. While the later can deal with it better by considering various factors.On the base of introducing the basis of e-government, including the conception, intension, development status and existing questions, according to the analysis and combining the new requiring of nowadays for e-government, this thesis pointed out the importance of cooperation on the actualization of e-government. According to the characteristic of e-government system, uniting the main content of cooperation theory, established the theory's base of the application of cooperation theory in e-government actualization. Then, we import the management of government affair flow, including it's mean in e-government actualization and the method in government affair flow rebuilding. At last, Petri Net was selected as model building tool, taking the dispatch of Office Automation system as example, government affair flow model based on workflow technology was established. After that, establish the model of multitask correlation relationship for determining the serial and parallel relationship when confront multitask. Through the mathematical analysis to key department scheduling arrange of multitask model, the least of working time loss of multitask team working was insured. For this, the existing algorithms were introduced. Through the discussion of complexity degree of algorithm, we offer an improved approximated algorithm referring might meet instance in actual application, then realize efficiency comparing between two algorithms by Matlab, emulation results obtained from the analyze of time after time operation, so the validity of approximated algorithm was approved.
