Prioritizing Water Pipe Renewal Using Fuzzy Set Theory / Priorytetyzacja Odnowy Przewodów Wodociągowych z Zastosowaniem Teorii Zbiorów Rozmytych.

The aim of this paper is to present the novel approach to risk assessment in combination with failure and consequence analysis, depending on two parameters defined by the fuzzy functions: the repair time of water pipe and the cost of water pipe repair, what allow to determine particular risk levels. The presented methodology can be used to describe the functioning of the public water supply in terms of its renewal. [ABSTRACT FROM AUTHOR]
