Study On Human Behavior Reliability In The Building Fire Evacuation

Fire is one of the most serious calamities that mankind is faced with, and building fire is the most direct and serious for the harm of people in the various fires of our country. The historical experience of studying building fire accident has also shown that when fire occurs and begins to evacuate , though the people characteristic is differ in thousands ways in the accident site, its physiological and psychological state, individual behavior and group behavior have its special law. This paper applies systematic safe behavior scientific fuzzy appraisement as well as mathematical statistics on the thought of systematic safety; the reliability that has behavior people in building fire is studied. Its major research has following content:1. The produced process, law and property of the perception are analyzed, the human perception mechanism and its influencing factors in building fire evacuation are studied, and the method of improving perception reliability is discussed simply.2. Analyzed on the current cognition and decision pattern, the pattern and the behavior characteristic of the human cognition and decision in building fire evacuation is put forward, and its principle is analyzed and studied, the influencing factors of the human cognition and decision in building fire evacuation are quested.3. Based on the mechanism of the human perception and the human cognition and decision in building fire evacuation, applied on the principle of behavior science, started with the human individual behavior and character, the mechanism of evacuation behavior pattern and influencing factors of the human physiological and psychological state, individual behavior, group behavior in building fire are analyzed and studied.4.According to the human behavior principle and its influence factors in building fire, the human key performance shaping factors in building fire is distinguished by the methods of combing set-valued statistic, principal components analysis and factors analysis, the index factors system of the human behavior reliability appraisement in building fire is established.5. Based on the index factors system of the human behavior reliability appraisement in building fire, the human behavior reliability model and its calculation method is set up applying on the method of fuzzy comprehensive evaluation, and then discussed its application combining with a example of a guesthouse fire.According to the building character and the human physiological and psychological characteristic showed in the occurrence of the fire, researching the human behavior reliability in building fire is important to instruct the evacuation in the fire building and make up the best emergency evacuation plan, at the same time, it has important value for design of the building fire protection system and establishment of the evacuation command system.
