Abstract
This paper provides an analytical method for evaluating production rates in serial lines having finite buffers and unreliable machines with arbitrary unimodal distributions of up- and downtime. Provided that each buffer is capable of accommodating at least one downtime of all machines in the system, we show that the production rate (a) is relatively insensitive to the type of up- and downtime distributions and (b) can be approximated by a linear function of their coefficients of variation. The results obtained are verified using Weibull, gamma, and log-normal probability distributions of up- and downtime.
