The Research On The Planning Process Modeling Of Railway Bureau Daily-Dispatching-Planning Based On Cooperative Mechanism

In the field of railway dispatching and commanding system, the daily plan is the key to achieve the optimal configuration of all resources and the effective cooperation of the general transportation organization and is the precondition of keeping a good transportation order and also has an important influence to the systematic efficiency. The research on process modeling of daily dispatching plan based on cooperative mechanism in this paper provides a theory base for constructing a cooperative planning system in which all types of dispatchers are involved. This paper will discuss this issue by3aspects as follows:The first aspect is the research on the decomposition and composing of complex process theory. Based on general process characteristics and the corresponding formalized, this part will describe the complicated cooperative process characteristics and propose the equivalence theorem of decomposition of complex process and strategies and also propose the equivalence theorem of sub-processes synthesis strategy after decomposition and explain the relationship between cooperation mechanisms and structures of the complicated cooperative process, and give the formalized definition of structural problems and the related theorem.Secondly, the cooperation mechanism modeling of daily dispatching plan in railway bureau is provided in this paper. The cooperation mechanism modeling is built by the method of hierarchical modeling. Planning the existing programming process, the cooperation mechanism is described in general and then a further cooperation mechanism modeling is built according to the organizational and functional relations.Thirdly, a man-machine cooperation model is constructed on the basis of Multi Agent Daily Dispatching Plan. The general man-machine cooperation model is constructed according to the Multi Agent technology and the hierarchical control structure. Furthermore, according to multi-agent model, the sub-process consisting of Multi Agent group and their relationship are explained specially, and a cooperative process of the hierarchical model is constructed based on a blackboard theory.With the model provided above, Transportation Dispatching Management System (TDMS4.0) is developed and its function is previewed and discussed, especially the key technology and practical application during the implementation.According to the research, the essential decomposition and synthesis theory of complex process is established. Based on the theory, a new final complex cooperative process model and a Synergy Multi-Agent Technology Man-machine cooperation model of daily dispatching plan are constructed by restructuring the complex process of current daily dispatching plan. The cooperative planning platform based on the model provides an effective support for the bureau’s daily dispatching plan in which all types of dispatchers in railway bureau are involved, and has the practical significance for a further cooperative planning across the local bureau jurisdiction and between the Ministry and the bureau and constructing super large network cooperative railway dispatching plan systems aiming at the whole country.
