Availability and cost–benefit analysis of a fault tolerant series–parallel system with human-robotic operators

Abstract Without excellent system uptime and profit margins, many manufacturing systems will not be able to continue operating. Strong business performance of companies is facilitated by availability generation. Most are set up in series–parallel, parallel-series, or hybrid configurations. In this present study, we analyze a series–parallel composed two subsystems with the following specifications: subsystem A consists similar units/components that operated Human, whereas B made Robot. We have also introduced fault tolerance factor work, so failure each unit subsystem, common cause as well due human error robot, accompanied factor. Our key goals examine how increase model’s profitability identify optimum maintenance plan. order meet these goals, certain expressions for reliability metrics been developed validated through numerical examples. Tables graphs used illustrate results form conclusions from them.
