A simulation modeling method and device for unconventional emergencies

Abstract

The present application provides a simulation modeling method and device for unconventional emergencies. The method comprises the following steps: acquiring a first attribute of a bearing entity, acquiring a second attribute of an external factor that can influence the development of the bearing entity, acquiring a changing relationship of the first attribute with time, and acquiring an association relationship between the first attribute and the second attribute, wherein there are a plurality of first attributes and a plurality of second attributes; determining a state variable, a rate variable, an auxiliary variable and an exogenous variable according to the first attribute and the second attribute; according to the time-varying relationship of the first attribute and an association relationship between the first attribute and the second attribute, constructing the state variables, rate variables, exogenous variables and auxiliary variables, and generating a simulation model of unconventional emergencies. Embodiments of the present application can efficiently and dynamically reflect unconventional emergencies through dynamic simulation modeling, and cross-disciplinary and cross-disciplinary dynamic simulation research on unconventional emergencies evolution intervention can be carried out.

Description

technical field [0001] The present application relates to the construction field of virtual systems, in particular, to a simulation modeling method and device for unconventional emergencies. Background technique [0002] Unconventional emergencies refer to low-frequency occurrences, seldom or no occurrences in history, high nonlinearity, structural uncertainty, complex occurrence, development and evolution process, and severe secondary derivative disasters , events whose modality is difficult to predict, such as: flood disasters, earthquake disasters, and debris flow disasters. [0003] The dynamic simulation system for unconventional emergency evolution intervention, as an important means to grasp the evolution law of unconventional emergencies and an experimental tool for emergency decision-making, is of great significance to effectively respond to unconventional emergencies. The conceptual model of unconventional emergencies, as a preliminary abstraction of the evolution...

Problems solved by technology

The modeling method of unconventional emergencies based on disaster law makes the dynamic simulation research on the evolution intervention of unconventional emergencies limited to a specific field; although the modeling method of unconventional emergencies based on knowledge elements can Solve the problem of comprehensive interpretation of cross-domain and interdisciplinary knowledge in the dynamic simulation of unconventional emergencies, but the modeling method of unconventional emergencies based on knowledge elements mainly expresses the static relationship between knowledge elements in emergencies

[0005] Therefore, the need to reflect unconventional emergencies efficiently and dynamically, and conduct dynamic simulation research on the evolution intervention of unconventional emergencies across fields and disciplines cannot be met.
