공동주택의 관리비 추계모델과 증감특성

Maintenance cost depends on various factors. These are building volume, floor area, number of household and so on. Maintenance cost of the apartment housing is affected by the maintenance characteristics, building physical factor, socio-geographic aspects. Among these, the maintenance characteristics is represented by the total floor area and number of household which is main factor to provide the roughly building size. In this paper, it aimed at modelling the estimation function of the maintenance cost with the total floor area and number of household. Items of maintenance cost is various in general cost, repair cost and so on. We classified various cost item into the 5 categories. These are general cost, facility maintenance cost, utilization cost, insurance and sanitary cost. The estimation function is more appropriate in power function than any other estimation methods in statistics. Power function has a three type with curve to concave and convex and linear style. The estimated models have a goodness-of-fit in determinant and parameter.
