Uncapacitated Lot Sizing (ULS) is a classic OR problem that seeks to minimize the cost of satisfying known demand for a product over time. Demand is subject to varying costs for production, set-up, and storage of the product. Technically, it is a mixed binary integer linear program – the key point separating it from the world of linear optimization being that production cannot occur during any period without paying that period’s fixed costs for set-up....
