Research And Application Of BDI Agent Based Reasoning And Multi-department Emergency Negotiation

In recent years, a variety of emergency events occur with an increasing rate due to anumber of unstable factors caused in the course of rapid social and economic development.Emergency decision-making, which is a dynamic decision-making process before andafter the occurrence of an emergency event, has attracted more and more attentions. As atypical natural disaster, flood is featured by its geographically widely distributedinfluenced areas, severe consequences, as well as the variety and the amount oforganizations and individuals involved in the emergency response process. Under thiscircumstance a consistent task goal obtained via organizing related organizations,assigning tasks, sharing information, and effective communication is the fundamental ofefficient emergency response.This paper aims at the inner reasoning process of an organization and the negotiationamong multi-organizations in emergency response. In particular,For the theoretical study perspective, this paper investigates the BDI agent basedreasoning and negotiation methodology considering the characteristics of emergencyresponse:(1) For the individual BDI agent reasoning, extend the Belief model takingpersonality into consideration, and extend the Desire model taking multi-objective andweights into consideration;(2) For multi-organization negotiation, combine BDI theorywith game theory, utilize classic concession negotiations with limited negotiation rounds,but without utility function;(3) Consider the organizational structure and social norms inthe emergency decision-making process.For the practice perspective, this paper applied the proposed methods into theemergency response for the Three Gorges flood:(1) Build BDI agent models for theorganizations involved based on the analysis of real flood response process;(2) Realizethe auto-negotiation process to obtain a consistently agreed flood dispatching schemeusing JACK simulation platform, and evaluate the influence of time, personality, and floodfrequency on negotiation results.
