Abstract [en]
Customer waiting time is a critical variable in heuristic modelling of multi-echelon inventory systems. It is not sufficiently investigated in the literature, which is large.
The paper reviews and comments the literature and extends it by investigating customer waiting times in (nQ,R) inventory systems with continuous review and compound Poisson demand and with R+1<0 allowed. Two basic cases are considered: the waiting time for an average unit of demand assuming partial deliveries, and the waiting time for a customer demanding d units when only full deliveries are allowed.
The probability distributions are characterized and exact and approximate formulae are derived for means and variances. There are some computational results of various heuristics for the mean and variance of waiting time in each of the cases.
