Abstract: Abstract The fill rate service measure describes the proportion of customers who commence service immediately upon arrival. Since, however, customers will usually tolerate a certain wait time, managers should consider the window fill rate in lieu of the fill rate. That is, the performance measure of interest is the probability that a customer is served within the tolerable wait time. In this paper, we develop approximation formulas for the window fill rate in a two-echelon, exchangeable-item repair system in which the upper echelon is a central depot and the lower echelon comprises multiple locations. We demonstrate the use of the formulas through a numerical example and measure the approximation error of the window fill rate formulas using simulation.
