Design And Implementation Of Contract Management System In Hunan Electric Power Company

With the constant specification of the working process of the electric power company and the constant improvement of contract laws and the laws and regulations concerning electric power, the company makes higher and higher demands of the contract management of grid engineering project. The Project information can not be shared fully in the Construction and Operation Ministry and construction companies in the original contract management system, head of the related department and executives can not have access to the project’s real-time information timely, the uniqueness and the integrity of the data can not be guaranteed.This topic is from the actual situation of engineering contract of Hunan Electric Power Company, the requirement of the system is analyzed via survey, understand the system function, performance requirements, data requirements from the user’s points of view, and we use UML and forms to design and analyze the system through the real case and business process.1. In terms of function design, we analyze basic business of contract management by using the related software engineering technologies, design related function modules, including project management, contract management, process management, historical data process of contracts, system settings management and so on. At the same time, it can use Visual Staudio 2010, C# to design and develop platforms.2. In terms of technology implementation, using SQL SERVER 2008 database and connecting with the real requirements to establish corresponding database, and it can calculate and do statistics. To achieve dynamic organization and flexible grading management, through authorizing institutions, sectors roles and users. It can use reliable encryption technology to store information on contracts and funds as a coded file, which can ensure the security and reliability of information. The selection of B/S structure can make the system highly flexible and easy to integrate with external systems. Using the WorkFlow technology to realize the signing of the contract, transfer, payment approval process to improve work efficiency. The use of Web service technology can make the two systems of the construction department and construction company seamlessly operate, which can not only ensure the independence of the two sets of systems, but also realize information sharing of the two sets.System function tests show that the contract management system of Hunan electric power company, which has a friendly interface, easy to use. To solve the centralized planning, decentralized implementation, a full range of large project problem by using computer network and software technology, the use of process control to solve the data of each item and uniqueness, integrity and the sharing problem, to achieve a high degree of information sharing.
