Abstract:

The scenarios of unconventional emergencies are highly complex and uncertain, which means that the generation of emergency response plans must consider the needs of subsequent dynamic adjustment and the generated plans must have the characteristics of flexible adjustment. In addition, there are often multiple conflicting goals in the process of emergency response. How to balance the conflicting goals and make the generated plans more scientific and reasonable is also a problem that must be considered. There is still room for improvement and expansion in the existing researches on the above two aspects. Improvisational decision-making provides an effective mode or means for improvisational generation and dynamic adjustment of emergency response plans for unconventional emergencies, but the operable models and methods in its key links still need to be further studied. In order to improve the flexibility of the generation of emergency response plans for unconventional emergencies, an emergency response plan model is constructed based on the idea of improvisational decision-making and with emergency response activities as the core. For the sake of generating a satisfactory and feasible emergency response plan, taking emergency response activities as the programming objects, and taking resources, time and order relations of emergency response activities as constraints, a multi-objective programming model for improvisational generation of emergency response plans is established to minimize rescue time, minimize response cost and optimize the balance of resource allocation. With the help of the non-dominant ranking evolutionary algorithm with elite strategy and the optimal compromise solution selection based on the fuzzy set theory, the multi-objective programming model is solved and the plan is optimized, so that when there is a “mismatch” between the response ability of the existing plan and the current scenario at any moment, the effective emergency response plan can be obtained through the reconfiguration of emergency response activities. By systematically collecting, analyzing and summarizing relevant survey data obtained from Ministry of Emergency Management, news content, emergency preplans and references, a case study of improvisational generation of the emergency response plan of Yancheng “3.21” chemical plant explosion accident is carried out, and the scientificity and effectiveness of the proposed model and method is verified by solving the case-based problem. The results show that fine-grained representation of emergency response activities improve the flexibility and reconfigurable of emergency response plans, and provide basic active elements for the improvisational generation of emergency response plans. The further refinement of the elements of emergency response activities such as time, resource and priority ensures that the generated plans meet the requirements of time, cost and fairness for emergency response. The proposed multi-objective programming model and the corresponding solving algorithm for improvisational generation of emergency response plans not only enrich the connotation of improvisational decision-making, but also improve the operability and feasibility of the application of improvisational decision-making in the generation of emergency response plans for unconventional emergencies, and then provide some reference for the further improvement and deepening of the theories and methods of emergency decision-making.

Key words: unconventional emergency, plan generation, improvisational decision-making, emergency response activity, multi-objective programming
