Abstract
For every unit system, the number of cold standby units must be optimized to increase reliability and to get the maximum profit to sustain the economy and industries. Thus, a reliability model with N (a finite number) cold standby units along with a single operating unit with activation time is required to make the cold standby unit operative on need. When an operative unit fails, one of the cold standby units gets activated to become operative, functioning as effectively as the operating unit. The system is such that it needs only one working unit at a time. Computational analysis has been obtained to estimate how many standby units the system needs, cut-off points for revenue, installation costs, failure rates, activation rates, etc. The Markov process and various performability measures have been obtained using the regeneration point technique to optimize the value of N.
