Abstract [en]

Spare parts needs - as an issue in the field of product support - are dependent on the technical characteristics of the product, e.g. its reliability and maintainability, and the operating environment in which the product is going to be used (e.g. the temperature, humidity, and the user/operator's skills and capabilities), which constitute covariates. The covariates have a significant influence on the system reliability characteristics and consequently on the system failure and number of required spare parts. Ignoring this factor might cause irretrievable losses in terms of production and ultimately in terms of economy. This was proved by the event tree risk analysis method used in a new and non-standard form in the present paper. It has been found that the percentage of risk associated with not considering the system operating environment in spare parts estimation is relatively high.
