Disney", abstract = "Using value stream maps, we find there are three lead times in a single supply chain echelon: the customer, supplier, and production lead time. There are two replenishment policies; one determines production quantities, the other orders raw material. Our parsimonious model captures the dynamics of both make-to-stock and make-to-order systems." }
