Single-period inventory models with demand uncertainty and quantity discounts: Behavioral implications and a new solution procedure. (English) Zbl 0597.90024

Summary: Quantity discounts are considered in the context of the single-period inventory model known as ”the newsboy problem”. It is argued that the behavioral implications of the all-units discount schedule are more complex and interesting than the literature has suggested. Consideration of this behavior and the use of marginal analysis lead to a new method for solving this problem that is both conceptually simpler and more efficient than the traditional approach. This marginal-cost solution procedure is described graphically, an algorithm is presented, and an example is used to demonstrate that this solution procedure can be extended easily to handle complex discount schedules, such as some combined (simultaneously applied) purchasing and transportation cost discount schedules.
