Emergency reasoning model of urban emergencies based on event chain

Abstract

The invention discloses an emergency reasoning model of urban emergencies based on an event chain, Event containers and environmental information funnel filtration are established. Combined with stochastic forest algorithm, the operation mechanism, emergency chain evolution and emergency decision-making, efficiency-driven emergency decision-making and resource-driven emergency decision-making arededuced. In the above manner, the present invention can solve the changing situation of various emergencies in cities such as natural disasters, accident disasters, public health events, social security events and the like, establish an emergency reasoning model, and provide a decision analysis basis and a reference for the subsequent decision analysis of urban emergencies.

Description

technical field [0001] The invention relates to emergency reasoning for urban emergencies, in particular to an event chain-based emergency reasoning model for urban emergencies. Background technique [0002] The event chain-based emergency reasoning model for urban emergencies is supported by event chains, event containers, environmental funnels, case reasoning (CBR), and random forest algorithms. Disasters, accidents, disasters, public health and social security and other areas of hazards of emergencies have important practical significance. [0003] In recent years, the frequency of various natural, public and social unconventional emergencies has increased significantly, and the degree of harm and the scope of influence are very large. The Chinese government has traditionally centered on "one case, three systems" and the "People's Republic of China According to the Emergency Response Law of the People's Republic of China, the emergency response to various emergencies has...

AI Technical Summary

Problems solved by technology

[0004] (1) There is a lack of a structured description framework for emergencies, and it is difficult to extract event information in the event of an emergency, so as to provide reference for leadership decision-making analysis and subsequent formulation of disposal measures;

[0005] (2) Less consideration is given to the operating mechanism of emergencies, and there is a lack of unified consideration and analysis of whether other events will be triggered after the emergency occurs, and secondary and derivative events;

[0006] (3) Lack of event collection, event container modeling, and reasoning rule algorithms for existing urban emergency cases, without reasonable classification, it is difficult to effectively serve the retrieval, reuse and reasoning of previous cases;

[0007] (4) The emergency chain response model is single, the internal elements of each event in the event chain and the relationship between events, and the network structure is not clear
