| With the social, economic, cultural, and other aspects' development, the decision-makers of the majority of the enterprises have an urgent requirement to clarify the existing problems, the early warning of the problems, strategy generation, assistant decision-making etc. However, with the development of network technology, faced with a deluge of information, if the business decision-makers want to fully understand their situation, to grasp the problems they are facing with, and to make a strategy to solve problems, they need to turn to the Internet and computer technology for help.Extension is a science to study the possibility of things' extension and the regulation and method of innovation by the formation model, then applied to solve of the contradictories. With the continuous improvement and development of the extension, now the study of the (extension strategy generating system, ESGS) have been put forwards.Firstly, this thesis introduced extension, the study condition of ESGS, the background and the significance of this study, and then the main contents of this thesis.Then, this thesis introduced the extension and the basic knowledge of ESGS, the ideas and basic steps of ESGS. And it analyzed the concepts of the extension model, the analysis of the extension, the transform of the extension, the excellent evaluation, etc. Then it introduced the relevant calculation formula this thesis used. It also introduced the systems development under the framework of Java EE 5 and component-oriented Development technology.Then, the thesis takes the solution of the regional conflicts of sulfur dioxide concentrations as example. According to the framework of the ESGS and the kernel model of the issue, through analysis by the relevant network of a number of factors of regional impact of sulfur dioxide concentration and the causal relationship of their interactions, through the extension reasoning and the contradictory-solving strategies of the extension transformation generation, and it selected the optimum strategy that to control the sulfur dioxide concentrations through the flue gas desulphurization. The analysis of the whole process also reflects the basic steps of ESGS.Finally, applying for component-oriented development of technology, through the platform of Java EE 5, it has realized a component-based extension strategy generation system. This system uses the MVC development model, combines the JSP, Servlet, EJB, and other technologies, and greatly increases the reusability and maintainability of the system.The creative work in this thesis is as follows:1. The innovation of this thesis is to apply the basic theory of the extension and the method of extension project to the strategy generating system for air pollution prevention. It presents the process of implement the extension strategy generating system on computer to solve the regional S02 concentration contradiction problem and shows the running results.2. In order to improve the reusability and reliability and maintainability, in the process of development, the thesis introduced an idea of component that a component-oriented software development method made the system more flexible and reusable. It can meet the needs of different users and the changing demand of business function through the replacement of its components.This thesis is the research finding of the project supported by theGuangdong Provincial Natural Science Foundation--the research of the"information - knowledge - the decision-making" system based on extension. |
