Study On Scheme Dispatch Program In Railway Subbureau Dispatch System

Train dispatch plays an important role in production for railway enterprises. The sub-bureau dispatch system aims at computer-assisted decision-making. Being a member of the project, the author has set up some key software models, exhaustively discussed its realization, analyzed problems, and advanced practical solutions. The thesis is of practical significance in designing and developing the dispatch system. The project involves the following works:Based on theory of information management and software engineering, the thesis has begun with a user survey, analyzed dispatchers' work, and given a full account of their responsibilities as well as their work process.The paper has set up system' s objectives, defined the basic subjects, and outlined the data process.The paper has build up the framework of the system, involving mode selection, development tool selection, functional module classification, and database designing and physical layer designing.The paper has analyzed and set up key models for scheme dispatch system, i.e. train streamline model, train work scheme model, train streamline operation model and train operation plan model, which serve as the crux of the project.By applying Java and Oracle, the developers of the system have accomplished the realization of the key classes and interfaces' encoding in the software, and the construction of the database.The thesis ends with a conclusion and prospect, pointing out problems and inadequacies, discussing the questions of the system structure mode, function, performance and the like.
