Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] Refer to attached figure 1 The schematic diagram of the modeling process of the railway emergency plan is shown, and the modeling process of the railway emergency plan is as follows:

[0026] Step 101, through field research and data analysis, there are many types of existing railway emergency plans;

[0027] Step 102, after abstraction and standardization, the plan is divided and sorted into several templates;

[0028] Step 103, respectively, templates for prevention and early warning, templates for information reporting, templates for response grading and classification, templates for organizational structures, templates for emergency support, templates for post-processing, etc.;

[0029] Step 104, on the basis of the above templates, these templates are subdivided into two types: comprehensive and station sections; taking ...

Abstract

The invention discloses a modeling method of the railway emergency plan based on the random Petri net, which relates to the railway emergency plan processing technical field; the technical proposal includes that the type and rank of the current railway emergency plan are analyzed; the emergency plan is classified and prepared to realize the template of the emergency plan content; the common contents in various accident rescues in the emergency plan are extracted; the emergency plan is classified into flows through the preparation of the common contents; the emergency plan flows are processed with qualitative analysis and quantitative analysis based on the Petri net theory, so as to establish the Petri models for the classified emergency flows; a plurality of single models are combined to an integral model through the interrelation of the models; the integral model is processed with performance equivalent simplification; finally, the simplified simple models are combined to obtain the SPN model with integral simplification. The SPN model established by the modeling method is adopted to realize the systematical, digital and intelligent management of the railway emergency plan.

Description

technical field [0001] The invention belongs to the technical field of railway emergency plan processing, in particular to a modeling method of a railway emergency plan based on a stochastic Petri net. Background technique [0002] At present, there are many problems in the construction of my country's railway emergency plan system, which are manifested in: the emphasis on emergency plans, especially operational plans, is generally insufficient, the preparation is not perfect, and the implementation is not strong enough; the technical support means of emergency plans are very backward, and the existing technology platform It has become a bottleneck for the effectiveness of a large number of prepared plans. [0003] However, the existing railway emergency plan management system contains a large number of emergency plans of different types and levels. At the same time, the storage methods of the data and files of these plans are outdated, the management form is unreasonable, it...
