Webperiods in which starting inventory is zero. Wagner and Whitin propose an efficient forward dynamic programming (DP) algorithm to solve their problem. The model and solution method of Wagner and Whitin have since been generalized to models with more general costs functions (Eppen et al. 1969, Wag-ner 1960, Zabel 1964, Zangwill 1969). They have … Webalso a natural extension of the deterministic problems solved by Wagner and Whitin (1958) and Zangwill (1967). In addition, we characterize optimal solutions when orders are permitted to cross in time. In this case an order need not consist of a set of consecutive demands but it is still "lumpy" in the sense that it will exactly satisfy a taper imaging center

The dynamic lot-size model in inventory theory, is a generalization of the economic order quantity model that takes into account that demand for the product varies over time. The model was introduced by Harvey M. Wagner and Thomson M. Whitin in 1958. See more We have available a forecast of product demand dt over a relevant time horizon t=1,2,...,N (for example we might know how many widgets will be needed each week for the next 52 weeks). There is a setup cost st … See more • Infinite fill rate for the part being produced: Economic order quantity • Constant fill rate for the part being produced: See more • Solving the Lot Sizing Problem using the Wagner-Whitin Algorithm • Dynamic lot size model See more The precedent theorems are used in the proof of the Planning Horizon Theorem.

The additional feature is that in each period a deterministic amount of returned items (returns for short) enters the system. These returns can be remanufactured to satisfy demand besides regular manufacturing.
