Problems solved by technology

The existing emergency process management method is to implement emergency rescue actions according to the emergency plan after the disaster occurs. However, the content of the emergency plan is relatively general, and only provides a general general specification, and does not give a specific scheduling method for emergency rescue r

Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0053] The process described in the existing petrochemical enterprise safety emergency plan can be generally divided into four parts: early warning reporting, expert decision-making, emergency rescue, post-processing process, etc. Early warning reporting is real-time monitoring of on-site data. In the event of an abnormal state, the early warning mechanism is activated through the data acquisition system or manual alarm, and the disaster level is classified and reported to the leading agency. Expert decision-making is the process of organizing experts to determine the emergency rescue plan immediately after the accident and disaster. During the decision-making process, the members of the expert team will use the data collected on the spot and disaster information, and consult with the emergency plan to determine the final rescue plan. Emergency...

Abstract

The invention discloses a time Petri net based emergency rescue resource scheduling method and an emergency rescue method. The time Petri net based emergency rescue resource scheduling method comprises the steps of: analyzing existing contingency plans of petrochemical enterprises, extracting emergency rescue action actuating logics, establishing a Petri net model and finding out emergency rescue resources required by each emergency rescue action based on the contingency plans; analyzing states of the emergency rescue resources, and establishing a sub-Petri net model in the preparing and using processes of the emergency rescue resources; integrating the Petri net model and the sub-Petri net model to establish an emergency rescue resource scheduling Petri net model; configuring initial and target identifiers of the emergency rescue resource scheduling Petri net model, calling a solution algorithm to solve a change excitation strategy with the least accomplishing time and obtaining an optimized emergency rescue resource scheduling strategy. The emergency rescue resources can be adjusted in time based on the real-time fire condition, so that the time Petri net based emergency rescue resource scheduling method improves disaster rescue efficiency and is suitable for fire situations with concurrence of secondary disasters in a resource coupling state.

Description

technical field [0001] The invention relates to the technical field of safety emergency management in petrochemical enterprise plants, in particular to an emergency rescue resource scheduling and emergency rescue method based on time Petri nets. Background technique [0002] Accidents and disasters (mainly referring to fire or explosion) in petrochemical enterprises are random and complex. The choice of fire extinguishing strategy is restricted by many factors such as the time, location, weather, and burning objects of the fire. Even if the same object is on fire, it will Due to the different environment of the fire scene, the quality of the fire extinguishing force and equipment and other factors, different fire fighting methods need to be adopted. The fire fighting of petrochemical enterprises is a very complex dynamic process, including the whole process from receiving the fire alarm to the end of the rescue. The petri net theory can be used to establish a model of the f...
