The dynamic lot size model with quantity discount
Coauthor(s): Chung-Yee Lee.
This article treats the dynamic lot size model with quantity discount in purchase price. We study the problem with two different cost structures: the all-units-discount cost structure and the incremental-discount cost structure. We solve the problem under both discount cost structures by dynamic programming algorithms of complexity O(T3) and O(T2), respectively, with T the number of periods in the planning horizon.
