Emergency rehabilitation is an important affair after an earthquake. Therefore, people tolerated the time of repair must be short in a condition which is the crucial road networks and transportation systems are damaged. But how much time is it which involved fuzzy concept. Emergency managers hope to repair the crucial road networks and transportation systems as fast as possible. Troops repaired a disaster which is often affected by some factors. The factors are caused repair time becoming uncertain. The research is hoped to the point of view to people and emergency managers, to construct “peoples’ toleration for repair time of the roads’’. And then the research discussed whether repair time is long, troops whether enough, the information hoped to be beneficial to emergency managers. According to above-mentioned which is the peoples’ toleration for repair time of the problem, the research used intrinsic fuzziness to deal with the questionnaire for the people tolerated the repaired time. And then used to fuzzy statistic to analyze the questionnaire, and constructed the fuzzy number of people tolerated the repaired time. Simultaneously, the research is constructed the model of multiple depot fuzzy repair vehicle routing, which considers uncertain information. The research also applied a heuristic algorithm to solve the problem, and examined real applications. And then obtaining the fuzzy number of finished time in the real applications. According to above-mentioned the outcome of fuzzy number, the research is constructed peoples’ toleration for repair time of the roads. Finally, the research is discussed the conclusion and suggestion.
