D. Pandey et al., RELIABILITY-ANALYSIS OF A POWERLOOM PLANT WITH COLD STANDBY FOR ITS STRATEGIC UNIT, Microelectronics and reliability, 36(1), 1996, pp. 115-119
A powerloom plant consists of two units A and B(n) connected in series
. Unit B(n) has n components in parallel redundancy that carry threads
of different varieties/colours to unit A. Unit A is the strategic uni
t that weaves these threads together and produces a long piece of clot
h of some standard size. Failure of unit A makes the entire system fai
l whereas the failure of k components out of n in unit B(n) results in
the system working in a degraded state. The present paper deals with
the reliability analysis of the powerloom plant with a cold standby fo
r its strategic unit. The common cause failure and critical human erro
rs have also been considered to avoid overestimation of the reliabilit
y of the system. Results of Dhillon [Int. J. syst. Sci. 23, 1277-1287
(1992)] have been deduced as a particular case of our result.
