PROVIDING OF RESERVE PARTS
Spare parts are parts of machines, plants and equipment (technical systems) that should be available for replacement when canceling them for various reasons - breaks, abrasion and deformation. By replacing them, the observed technical system places itself in the possibility of functional use. In order to enable the possibility of eliminating failur...

EFFECT OF THE TURBINE CLOSING TIME ON THE WATER FLOW IN THE SUPPLY SYSTEM OF A DIVERSION HYDROPOWER PLANT WITH A SURGE TANK
In this paper, a model based on numerical solution of two ordinary differential equations is used to obtain the water level in the surge tank and the static pressure in the headrace tunnel – the properties of essential importance for the functioning of the water supply system during the turbine shut-off. The model allows a fast and reliable s...

ATTRIBUTIONAL VERSUS CONSEQUENTIONAL LIFE CYCLE ASSESSMENT MODELLING IN METALWORKING PRODUCTION SYSTEM
Two different system modelling can be distinguished in life cycle assessment: attributional and consequential. Attributional modelling is used to describe the present state of the examined system and is characterised with use of allocation, no substitutions, market average suppliers, and cut-off principle. Consequential modelling is used to describ...

CALCULATION INDEX OF RELIABILITY ON THE EXAMPLE OF THE SHED OF A STEEL HALL, COMPARATION OF PTP AND EC-1 REGULATIONS FOR SNOW LOAD
This paper deals with the resistance of the shed of a steel hall in Drvar according to technical regulations for snow from 1961 and EC1 regulations. The paper aims to check the reliability of the shed with probabilistic approach. That also implies calibration of the steel hall construction analyzed with classic deterministic method. Statical system...
