Extended optimal replacement model for deteriorating systems

Article Abstract:

A study was conducted to characterize a replacement framework supporting a deteriorating system with two kinds of failures. The probability of the two types of failures was assumed to correlate with the number of failures since the last replacement. In addition, the model supported operating intervals that were stochastically decreasing and consecutive repair intervals that become longer. It was also assumed that the original system operated at a time of 0.
