Research Of Dispatching Security Management System Of Railway Business

With the coming of information time and rapid development of communication technologies, services, customers and the communication network are sharp increasing. There are some new characteristics of the communication network, such as the performance is stronger, the deployment is wider and the security is higher. The most important works for the telecom companies are reforming the operational mode, improving the efficiency, reducing the cost and ameliorating the security. Therefore, Tietong Company has brought forwards the demand of "Dispatching Security Management System of Railway Business".The paper firstly select ASP.NET to design the system because of its strong management function and cheap development cost. Besides, it does not have to do any special configuration to hardware and update to operating system when it is used. After comparing and analyzing the characteristics of C/S and B/S, we select the B/S framework according to the characteristics of the dispatching security management of railway business.The paper then builds model of railway business information management system using the Petri net based designing patterns. The paper puts forward the architecture of workflow management system based on tree layers dispatching mechanism of security management, coming true by differentiating the affection of workflow's three basics element and dividing it into three layers. We also simplify workflow's execution and improve the workflow's flexibility and its support to the complicated business process application.After the modeling of the dispatching security management system according to the actual work flow, the paper then analyze the liveness, reachability, boundedness, safeness and efficiency of the model in detail. We prove the accuracy of our model according to the above characteristics.Finally the paper develops the failure management, emergency management, work management, announcement of railway business, contract management, BBS of railway business and system manage based on the model. Apart from this, we develop the security strategy of role based access control and XML based data exchanging of different database systems. The system has already been applied in Tietong successfully. After the practice, it is proved that this system has realized expense settlement management, dispatching security management, synthetic service management and system management functions. This system can not only meet the actual railway business needs of Tietong, but also raise the expense settlement efficiency and the dispatching management security significantly. Otherwise, it can reduce the management cost.
