Abstract
The paper focuses on computer modeling of the reliability of technical systems using FlexSim simulation software. It presents the theoretical foundations of machine reliability and principles of describing this phenomenon. The discussion demonstrates how to estimate the main parameters of reliability analysis - MTBF and MTTR. The end result was designing a simulation model and assessing the impact of machine failure on the productivity and performance of a technical system.
Highlights
According to the terminological standard PN-93/N-50191 [1], object reliability is "a set of properties that describe the readiness of the object and reliability, maintainability and maintenance support"
Methods for calculating the value of MTBF using statistical distributions can be found in the literature [7]
The total reliability of a technical system depends on the reliability of all its components, as well as the configuration of connections between individual machines
Summary
According to the terminological standard PN-93/N-50191 [1], object reliability is "a set of properties that describe the readiness of the object and reliability, maintainability and maintenance support". This definition was supplemented by the comment that "the term reliability is used only for a general non-numerical description". A closer look at the concept of reliability, in terms of operational analysis and technical design, requires the object of the research to be the object itself, but its operating system as well, including its reliability [2]. The phenomenon is widely described in the literature [5,6] using the general formula (1), where f (x) is the probability distribution for breakdown
