RELIABILITY AND COST ANALYSIS COMPARISON BETWEEN TWO-UNIT PARALLEL SYSTEMS WITH NON-IDENTICAL AND IDENTICAL CONSUMABLE UNITS

Anil Chandra, Anjali Naithani, Surbhi Gupta, Chandra K Jaggi.

Abstract
In this paper, reliability and cost analysis of two different two-unit parallel redundant systems with non identical and identical consumable units respectively have been done by employing Semi – Markov Processes and Regenerative Point Technique and a comparison is made between both the systems. The systems being considered are two inkjet printers with different cartridge arrangements. The first system contains two non-identical consumable units, colour and black cartridges, wherein, failure of one unit results in system being operative under reduced efficiency. However, the second system contains two identical consumable units, both colour cartridges, wherein, failure of any one of the units does not affect efficiency of system. The system may also fail due to other technical failures. Various system efficiency indicators such as Mean Time to System Failure (MTSF), Availability and Expected Down-Time of the System, Busy Time Period of Repairman, and Average Number of (damaged) Unit Replacements are estimated. Using data collected from industry, the parameters are used to estimate reliability parameters of both the printers and a comparison of profits of both systems with respect to time has been done. Subsequently, the differences in behavior of Availability and Profitability of both systems due to variations in its parameters have been analyzed.

Key words: Semi Markov Process, Regenerative Point Technique, Two Unit Parallel System, Inkjet Cartridges, Inkjet Printer
