Modelling maintenance costs of buildings under warranty
研究了保修期内建筑维护成本与项目成本、合同时间的关系，发现项目成本越高维护费用越高，合同时间越长费用越低，且费用呈抛物线分布。
Summary An essential link in building construction is maintenance under warranty. It is hardly possible to predict now how the cost and time of building construction will affect maintenance costs and alternations during this period. A correlation regression analysis has shown that the higher is the cost of the project, the higher the expenses, while the longer the time of the contract, the lower the costs. The total effect of the size and time of the project on the maintenance costs is positive implying that the higher they are, the greater are the expenses. Expenses under warranty spread parabolically, i. e. they are the highest at the beginning and at the end of the considered period and the lowest in the middle of the time. The cost and duration of a building contract has no direct impact on the distribution of building maintenance costs during the period under warranty.
