The Research And Development Of Enterprise Railway Dispatching Information System Based On The Workflow

Enterprise railway as part of the national railway network are similarities in thetransportation management and national railway network, But there are differences, Thedevelopment of the Enterprise railway and the improvement of production efficiency isclosely related to comprehensive transport efficiency of the national railway network， A lowlevel of information of enterprise railway compared with the national road network, In orderto respond to the call of realizing china’s railway transportation information, intelligence,automation， China should change the status of the production of enterprises railwaytransportation and improve the level of information management enterprises railwaydesperately needed. The paper analyzes the basic situation of enterprises railway dispatchinginformation system and the basic requirements of enterprise railway information, Thetraditional System functions as the target design patterns is changed, the research anddevelopment of process-oriented enterprise railway dispatching information systems isProposed, Standardized processes for enterprise railway transport, Standardize thetransportation and production management， The application of the basic theory of Petri netand workflow， Enterprise railway dispatching information system process model isestablished.First, The current development of enterprise railway dispatching information system isanalyzed, The country’s national railway network current dispatching management system(TDCS) centralized and Centralized Traffic Control (CTC) function，Application of theAutonomous Decentralized System In other countries，The development direction railwaydispatching information systems in Foreign, The layout of the railway station Andcharacteristics of station operations， Application extended Petri net mapping railwaydispatching information system Routing Architecture，Modeling methods described in theworkflow.Secondly, Jiuquan Iron and Steel as the background, Analysis of the enterprise railwaytransport organization’s business processes, The definition of business processes with Petri，Adescription of each business process，Analysis of the core functions of Enterprise railwaydispatching information systems and the station subsystem, Application extended Petri nets,Establish an information flow control Enterprise railway business process workflow model,By extension color, Describing the flow of information in business processes (planningprocess), By extension level, Reducing the task node nets in the workflow net, Simplifies theworkflow net, By extensions identifying, Defines a trigger mechanism workflow system and Roles and tasks assigned，in the station subsystem, The establishment of a workflow modelroute automatically arranged，Information is updated of the car now car in the model isdefined as a task in the workflow model, Need to update the information now car in thebusiness processes, Station officers will be asked to timely update the now car, To maintainconsistency of information now cars of railway station and dispatching information systems.Finally, The design of the enterprise railway dispatching information system workflowengine, Defines the workflow persistence service database table structure, With WFdevelopment engine, The core interface of workflow engine be designed，In order to completecommunications services the process of host and workflow systems, Defines the Local serviceinterface of workflow events. Process design with WF state machine workflow processdesigner, Introduction WF environment a core component of the routing activities ofworkflow system，Finally, The user task list of workflow system basic functions is described.Workflow provides the modeling method of process model, The enterprise railwaydispatching information systems process model is built by workflow. Achieve automateddispatching processes of practical significance, Automation of our country’s railwaydispatching reference value.
