WebMay 1, 1997 · We describe a formulation of the dynamic lot sizing problem when demand is random and the costs are non-stationary. Assuming that the distribution of the cumulative demand is known for each period and that all unsatisfied demand is backordered, the problem can be modeled as a mixed integer nonlinear program. An optimal solution … WebOct 1, 2024 · Next, we present a numerical example to illustrate the problem. Example 1. Consider a problem with five periods and two stochastic demand timing intervals, i.e., T = …
