Abstract: Abstract This paper discussed the MTSF and profit analysis of a single-unit system with inspection for feasibility of repair beyond warranty subject to a single repair facility. Any failure during warranty is rectified by the manufacturer free of cost to the users provided failures are not due to the negligence of users. Beyond warranty, unit goes under inspection after failure for feasibility of its repair or replacement. The failure time of the system follows negative exponential distribution while repair and inspection time distributions are taken as arbitrary. The expressions for reliability, MTSF, availability of the system and profit function have been determined by using supplementary variable technique. Using Abel’s lemma steady state behavior of the system has been derived. The numerical results for reliability and profit function are also obtained by taking particular values of various parameters and repair cost.
