Reseach On Marching-on In-time Scheme And The Fast Algorithm Of Time Domain Integral Equation

The tobacco industry’s information construction has obtained certain achievements,such as information management mode of enterprise internal management, make the tobacco industry to move one step forward, but only limited to this, due to the incomplete information construction, most of the enterprise is stagnation in the enterprise internal system construction and even basic network infrastructure construction, and the construction of enterprise internal system is mostly separated from the independent, such as production information system, logistics information system,marketing information system to the enterprise internal management information system construction separately, make each department data information sharing are hard to come by, also lead to enterprises of all kinds of data is not very concentrated, thus affecting the long-term development of the tobacco industry.To improve the core competitiveness of enterprise, the enterprise informationization is inevitable, in order to better manage the enterprise internal scattered all kinds of data, for centralized data analysis, strengthen the enterprise internal communication between departments, build a suitable for the enterprise information system has become a necessity.In mianyang, this thesis is based on the specific situation of the tobacco business,build a suitable mianyang tobacco business structure of management information system. In both at home and abroad are analyzed in detail in the construction of management information system for tobacco industry status quo, mianyang, in combination with the actual situation of the tobacco industry, building design a management information system for tobacco enterprises in mianyang, the main content of this paper are arranged as following: the first part, this part firstly introduces research background and research significance of this paper, analysis of the current situation of the tobacco enterprise information system construction at home and abroad, the existing problems of tobacco enterprise management information system, and to solve the problem of domestic strategy, finally in this paper, the contents of the arrangements. The second part, this part mainly introduces the system introduces the technology development will be used, such as the system development. The.net framework technology, the system architecture of B/S mode and C/S mode, database SQL2008 andunified modeling language UML and MVC design pattern are made simple introduction.Third part, is the demand of the system analysis part, mainly according to the needs of users for the development of the system functional and nonfunctional requirements analysis, it is very important for system design and implementation of late. Demand analysis of the content mainly includes the system functional requirements, the work of the functional requirements, system use case analysis, database e-r entity contact analysis and so on. The fourth part, this part is the design and implementation of the system, according to the demand analysis, design and build corresponding management information system. The fifth part, this part is the summary and outlook for part of this paper, summarized the process of development of mianyang tobacco management information system, finally make a vision of the future.
