化工园区多Agent协同应急智能决策体系

Intelligent decision system of emergency response based on multi-Agent cooperation in chemical industry park

在应急响应不同阶段中,化工园区路网均处于应急救援与应急疏散等多种智能体(Agent)同步异构的活动状态,仅考虑单Agent在特定阶段的应急决策,难以为园区应急响应提供全方位支持。为探究园区应急响应全过程中各Agent的决策模型及其信息协同关系,本文基于混合式多Agent系统思想构建化工园区多Agent协同应急智能决策体系。首先,对应急响应4个等级进行改进,提出混合式智能决策体系框架;其次,对化工园区多Agent应急决策时空变化关系进行了分析,将园区多Agent应急响应全过程分为园区企业内部应急响应、园区内部应急响应、园区内外协同应急响应3个阶段;最后,基于混合式多Agent系统(MAS)与协同理论,构建基于三层应急智能决策模型的化工园区多Agent信息共享关系与协同模式,所提出的化工园区混合式三层多Agent应急响应全过程智能决策体系能够为化工园区应急决策提供重要的理论基础和技术支持。

The emergency response of the chemical industry park(CIP)has the spatial-temporal characteristics of dynamic and hierarchical emergency decision-making,conflict and synergy of the emergency rescue(ER),and the emergency evacuation(EE).In different emergency response stages,the road network of the CIP is in the state of synchronous heterogeneous activities,such as the ER Agent and the EE Agent.Therefore,a new method of route planning considers separate emergency response stages,is proposed in this study.Firstly,the four levels of emergency response are enhanced,and a hybrid intelligent decision-making system framework is proposed.Secondly,the temporal and spatial variation of multi-Agent emergency decision-making in the CIP is analyzed,and the multi-Agent intelligent decision-making models are established,respectively,for the emergency response stage inside the enterprises,the emergency response stage inside the CIP,and the collaborative emergency response stage both inside and outside the CIP.Finally,based on the hybrid MAS system and collaboration theory,the multi-agent information-sharing relationship and cooperation model based on three-tier emergency intelligent decision-making model in the CIP were constructed.The intelligent decision-making system for the whole process of emergency response can provide important theoretical basis and technical support for the emergency decision-making in the CIP.
