The paper describes aspects related to the reliability and its influence on life cycle cost analysis performance. The emphasis is on the unreliability costs, caused by failures, which are incurred over an entire object’s useful life. Later, there are characterized three methods, i.e. exponentially distributed failure rate, the determined failures frequency, and Weibull distributed failure rate, which allow to quantify the economic impact of the costs associated with reliability in the Life Cycle Cost Analysis. Applications of these approach to predict the unreliability costs of railbus electrical system are presented as well.
