Abstract
In this research, the fire mistaken dispatch records for the past 11 years have been analyzed by using a statistic technique. Fire mistaken dispatch occurred yearly average $48,371{\pm}5,763$ time at 95 % confidence level. This is 1.2 times more than the dispatch for extinguishing the fire. Fire mistaken dispatch has been increased mainly by malfunctioning alarm among other various reasons and the reason of mistaken dispatch is different depending on the population of the region. In big cities, the burning smell accounts for the most of mistaken dispatch but in rural areas, the garbage incineration is the major reason for mistaken dispatch. As a result of calculating the mean time between fire mistaken dispatches (MTBFmd) by region, MTBFmd of Daejeon is 20.61 hr/time and its reliability is 95.26 % at t=1 hr. On the other hand, the MTBFmd of Gyeonggi is 0.58 hr/time and its reliability is 17.91 % at t=1 hr.
