Based on the predicted information about remaining useful life
the joint decision on replacement time and spare ordering time for a single-unit system subject to condition monitoring is considered. First
the distribution function of the remaining useful life is predicted with real-time condition monitoring information; then
the sequential and joint optimization models are established based on the predicted information; finally
the effects of the joint decision and the sequential decision are compared by using the real bearing accelerated life test. The results illustrate that the joint decision is better
and it can avoid the problem under the sequential decision that decision results cannot be implemented.
