【 摘 要 】

The problem of ensuring an adequate level of the technical condition of a building occurs over the entire period it is in service. In solving problems connected with developing a prediction of changes in performance characteristics of a residential building, it is suggested that algorithms of determining changes in the reliability of technical devices be used. The process of changes in the technical condition of technical equipment can be managed by making decisions regarding repairs or replacing components. The prognosis of unfavourable processes will make it possible to determine the time frame in which the technical condition of a building will be unsatisfactory in the future, and thus necessitate repair works. Applying optimal prophylactic replacements requires a knowledge of the time span that the components of the building can be expected to work properly. To model situations in survival analysis, the Rayleigh distribution for the random variable of time was accepted. In the article, the model of the life span curve for a residential building has been presented, where the Pareto principle was applied as the strategy for undertaking renovation works. Modelling various scenarios of use helps to choose the optimal planning of renovation works on a building. The characteristics of various strategies influence the shape of the life cycle curve of the building. Applying the Pareto principle is an example of a strategy of renovation works on residential buildings. Applying the Raleigh distribution to predict reliability is possible thanks to the analysis of a set of data including the values of the degrees of wear of actual residential buildings.
