Reliability-exploitation analysis of the alarm columns of highway emergency communication system / Analiza niezawodnościowo-eksploatacyjna kolumn alarmowych autostradowego systemu łączności alarmowej

Abstract

Abstract The article presents issues concerning on the alarm columns of highway emergency communication system. The system is presented in general and then the reliability-exploitation analysis was done. This enabled preparing a development graph of the relationship, under which is created a set of Kolmogorov-Chapman equations describing the system. On this basis, it was possible to find the relation for calculating the probabilities of system staying (in symbolic terms) in the functional: states of full ability SPZ, impendency over safety SZB and unreliability of safety SB.
