Abstract
The quality of emergency training determines the professional ability of emergency personnel. To evaluate the safety of emergency training for building collapse ruin training scenarios, an approach combining analytic hierarchy process (AHP) and gray-fuzzy evaluation is proposed. According to the characteristics of building collapse ruin training scenarios and the principle of index selection, a safety evaluation index system for this training is constructed from four aspects: human, machine, environment, and management. AHP is used to determine the weight of each evaluation index, and the evaluation model is established base of the gray-fuzzy evaluation method. Based on the combination of the two methods, the quantitative results on training safety was obtained and the most important factor that have the greatest impact on training safety was found. Using this presented assessment method, the safety of an building collapse ruin training scenario for a domestic emergency training facility are assessed, the defects in its emergency capacity are determined, and measures and suggestions are recommended to provide scientific and effective basis for improving emergency capacity.
Highlights
People’s cognition of new technology and new materials is insufficient
This study combines analytic hierarchy process (AHP) with the gray fuzzy evaluation method and applies both to a training scenario of building collapse and ruins for the first time according to the expert survey method and brainstorming method
There is no comprehensive safety assessment study on emergency training sites for building collapse scenarios; there is a lack of identification and analysis of the influencing factors that affect the safety of trainers and no complete index system and assessment model
Summary
People’s cognition of new technology and new materials is insufficient. To a certain extent, this has caused frequent emergencies and introduced difficulties and challenges to the work of emergency rescue personnel [1], [2]. This study combines AHP with the gray fuzzy evaluation method and applies both to a training scenario of building collapse and ruins for the first time according to the expert survey method and brainstorming method. There is no comprehensive safety assessment study on emergency training sites for building collapse scenarios; there is a lack of identification and analysis of the influencing factors that affect the safety of trainers and no complete index system and assessment model. By the combination of AHP and grey fuzzy comprehensive evaluation, index weight analysis and quantitative safety assessment of emergency rescue training safety in building collapse accident scenarios can be carried out, the training safety level can be obtained, and safety recommendations can be provided . Based on the hierarchical structure of the safety assurance ability of the collapsed building ruin training scenario, the weight of each evaluation index was determined by AHP. Using the expert scoring method to score the third-level indicator Kij according to Table 2, the nth expert scores the indicator Kij as dinj (n=1, 2, . . . , m), which constitutes sample matrix D for the safety risk assessment of the scenario
