When supplierEs availability affects the replenishment lead time uAn extension of the supply-interruption problem

Article Abstract:

A continuous-review inventory system with compound Poisson demand, Erland-distributed lead times and random supply interruptions is analyzed. The supplier's availability in interpreting the lead time of a replenishment order is taken into account to do this analysis.
