Analysis And Design Of Workflow Model For S&T Project Assessment Based On Petri-Net

S&T (Science and Technology) project accreditation is an important work in the government. Scientific research activities are mainly leaded and supported by the government directly, and it charges the strategic mission of the country's development. Reforming the accreditation mechanism, Improving the efficiency and effectiveness of the accreditation, constructing technology assessment system are the important means of establishing scientific administrative examination and approval management and monitoring mechanism. It has positive and practical significance for improving the technology and impartiality of the science and technology project, improving government service level and efficiency.Workflow technologies is automation core technology for the realization of business process modeling, the simulation analysis and optimization for business process, and the management and integration business process. Right to use workflow technologies in its business process modeling and in-depth analysis can not only standardize the business processes, but also find the business process unreasonable links, as well as on the enterprise's business process optimization and reorganization. And the establishment of the business process model is a very important enterprise knowledge base and rule base, can be the guiding enterprises to implement computer management information system model. In-depth analysis of business needs based on the enterprise business model to the greatest extent improve the implementation and management of enterprise information systems Marketing success rate.This paper researches in technology assessment model analysis and design. Firstly, this paper comprehensively analyses the work flow modeling theory and technology assessment of the specific business, a technology assessment work flow modeling framework, and the work flow of each model of each sub-model for analysis. The following chapters, focusing on the analysis and design for the two most important model process model and resource model. In the third and fourth chapters, on the basis of the Administrative Process Reengineering theory, lists the design process and optimizing the design of the specific steps; Chapter five, using Timed Color Petri Net, designs resource management model and test the simulation model.During online assessment mechanism design and management information system development work, Construction of practical technology assessment model is the base of the building for projects assessment system, and is of great significance for the analysis of research for the assessment business processes and mechanism.
