dynamic-lot-sizing
by kishorkukreja
When the user wants to solve lot-sizing problems with time-varying costs or demand, handle non-stationary inventory systems, or optimize replenishment with changing parameters over time. Also use when the user mentions "time-varying lot sizing," "finite horizon lot sizing," "dynamic EOQ," "price changes over time," "seasonal lot sizing," "Wagner-Whitin with time-varying costs," or "rolling horizon planning." For stationary systems, see economic-order-quantity or lot-sizing-problems. For stochastic demand, see stochastic-inventory-models.
