A Method for Optimal Layout of Multiple Chemical Risk Sources

Abstract

The technical scheme discloses an optimized layout method of multiple chemical risk sources, which comprises the following steps of: computing the potential hazard, i.e. the risk level of the chemical risk sources by utilizing a poisonous gas diffusion mode, computing the gradient of controlled variables comprising chemical risk source position coordinates related to a site selection cost function containing land price cost, traffic cost and a penalty function through an accompanied mode, and computing the optimized layout of the chemical risk sources by applying gradient information iteration, i.e. adjusting the positions of the chemical risk sources by utilizing gradient information, and gradually iterating until the cost function is decreased to a minimal value, thereby not only avoiding that a protected object is seriously threatened by the chemical risk sources, but also enabling the economic cost of the chemical risk source layout to be minimal.

Description

technical field [0001] The invention relates to a method for controlling the hazards of air pollution chemical accidents, in particular to a method for optimizing the layout of multiple chemical risk sources, belonging to the field of chemical risk control. Background technique [0002] Air pollution chemical accidents are serious safety hazards that directly threaten people's lives and health and social stability. First of all, with the rapid growth of my country's chemical industry, the consumption of chemical raw materials is huge, and a considerable part of them is highly toxic. In the process of production, storage and transportation of these chemical raw materials, due to human or natural reasons, accidents of toxic chemical explosion or leakage may occur. Secondly, with the increasingly serious situation of terrorism, the possibility of terrorist attacks on civilian chemical facilities increases, and premeditated chemical terrorist attacks may cause disastrous conseq...

AI Technical Summary

Problems solved by technology

In the process of production, storage and transportation of these chemical raw materials, accidents of toxic chemical explosion or leakage may occur due to man-made or natural reasons.

Secondly, with the increasingly serious situation of terrorism, the possibility of terrorist attacks on civilian chemical facilities increases, and premeditated chemical terrorist attacks may cause disastrous consequences

If the leaked toxic chemicals are gaseous, or form toxic gases or aerosols due to volatilization, combustion, explosion, etc., they will easily spread in the atmosphere, seriously pollute the surrounding environment, and directly threaten the lives and health of people within the affected area.
