Computer-aided analysis of reliability and preventive maintenance optimization of radio communication equipment based on multivariate Monte Carlo simulation

Abstract

In the paper, mathematical support and software of a computer-aided design system of preventive maintenance schedule of radio communication equipment are proposed. Mathematical support is based on a Monte Carlo simulation model of an operational process that realizes multivariate approach of reliability indices estimation. System's software was implemented using C++ language and Matlab instruments. The developed system determines in an automated mode the recommended value of rational maintenance periodicity and reliability measures such as operational efficiency and availability for the selected device. The proposed computer-aided instrument was used for the estimation of the abovementioned characteristics for a real transmitter. The obtained value of the rational service periodicity compares favorably to the valid experimental data regarding failures of the transmitter.
