Abstract
The article draws close attention to the need to consider the impact of risk on the value of estimated life cycle cost of a building object. The main goal of the proposed approach to the risk assessment is to answer the question of consideration of the impact of the identified risk factor for a given component of the life cycle cost of a building object. This model of the reasoning mechanism is built based on fuzzy interpretation of two distinctive input variables for risk, ie. the probability and effect of a unwanted phenomenon. Due to the small number of input variables and thus the minimal possible number of reasoning rules, to the construction of the model used the fuzzy reasoning model of Mamdani. In order to choose the right defuzzification method, a comparative analysis of the five commonly used methods of defuzzification was performed. The Matlab’s “Fuzzy Inference System” was applied by the author to build “the Fuzzy Risk Assessment in the Life Cycle of a Building Object tool” and to analyze the selection of the right defuzzification method.
