Webframework, the model developed by Wagner and Whitin (1958) provides an appropriate solution for the firm’s planning. The Wagner-Whitin model is a dynamic lot-sizing model that produces an optimal lot size for each period. A notional example is developed for a firm using the “RoadHog” example from Hopp and Spearman (pp. 58-64, 2008).
