Abstract
In many cases, an interlocking system is required not only to dispose with the high safety integrity level, but also with high availability. Therefore, many manufacturers realize the interlocking system based on architecture 2003 or architecture 2 × (2002). The aim of the paper is to compare the safety integrity levels against random failures of two identical safety functions, that are implemented by the interlocking system with different architectures - architecture 2003 and architecture 2 × (2002). In order to observe the simultaneous influence of system and operational parameters of the interlocking system on the safety integrity against random failures of safety function, for model creation is used method based on the Markov chain theory. Based on mathematical description of created models are realized the calculations in software tool Wolfram Mathematica and the results are presented graphically.
