Researchand Implementation Of The Production Scheduling Information System In Locomotive Depot

Since entering the information era,the development of information has received attention from all professions and trades.The extent of informatization has even become an important basis,which measures the comprehensive development level of a country or region.Under this background,China railway industry has followed the trend of the times.A series of informatization development plannings have been formulated under the support of the China General Railway Company,which makes the informatization of railway industry in Chinaentering a stage of vigorous development.The current situation of information construction of a locomotive depot was investigated by this paper.Though some achievements have been made in the information construction,but some problems also exist,such as complexity and diverse of the information systems,trouble of logging in and the problem that data cannot be shared.Therefore,in order to solve the above problemsin this paper,research results of the railway information at home and abroad have been combined andthe SOA architecture,web service technology and Single-Sign-On technology have been used to integrate information system in locomotive depot.The main research contents are as follows:(1)The theory of information system interaction has been researched to achieve the locomotive depot information system integrationby using the SOA architecture and web service technology;(2)The information systems of the locomotive depot that are used now have beenunderstood through the on-the-spot investigation.And some detailed analysis of the business process of production scheduling of locomotive depot have been made to put forward some demands in the integration of information system;(3)The architecture of integrated information system has been designed.How to achieve the information system integration in the locomotive depotis explained from the views of data integration and application integration.The data integration includes the management of metadata,data integration andthe implementation of data access layer.The specific process of the Web Services' implementation,publishing and invocation are included in the application integration.(4)The SSO was introduced in detail.The CAS configuration's changes have been explained by the two angles of CAS server and CAS client to achieve the single sign on.The user management of integrated system was introducedand related interface were displayed.In this dissertation,the integration on production scheduling information system of locomotive depot has been achieved.The work efficiency has been improved by the full use of the achievements of information construction in the locomotive depot.
