Abstract : H.E. Lynch, R.S. Morris, Dr. R.J. McNichols, and Dr. D.R. Shreve have developed a prediction technique for the number of spares for a system, utilizing a prechosen probability level that sufficient spares would be available. The purpose of the paper is to test the technique. The testing of the prediction technique was done by using computer simulations. Basic systems were used with different probability density functions of time to failure used for the distribution of the processes in the systems. The same basic systems were used with the prediction technique to give results that could be compared. The results of this work showed that the prediction technique could be used in several cases to give estimates of the number of spares. In other cases the paper shows the variation between the prediction technique and the simulation. The use of the prediction technique depends upon the system and the probability density functions of time to failure. (Author)
