Reliability enhancement using optimization analysis
Scientific Journal of Silesian University of Technology. Series Transport, 2018 This paper presents an optimization analysis of a queuing system for a particular post office as a tool to increase system reliability. The consideration of system reliability in terms of queuing system failures is very relevant. One way to increase reliability is to analyse the system and its parameters in order to identify its most critical flaws. We
