The (Q,r) model addresses the question of when and how much to order, aiming to minimize total inventory costs, which typically include ordering costs, holding costs, and shortage costs. It specifies that an order of size Q should be placed when the inventory level reaches a reorder point r. The (Q,r) model is widely applied in various ...
Infinite fill rate for the part being produced: Economic order quantity; Constant fill rate for the part being produced: Economic production quantity; Demand is random: classical Newsvendor model; Continuous replenishment with backorders: (Q,r) model; Demand varies deterministically over time: Dynamic lot size model
Fillrate or fill rate can refer to: Fillrate, a measure of graphics performance; Service rate, a logistics measure of ordering performance;
One example of a service rate measures the number of units filled as a percentage of the total ordered and is known as fill rate. Fill rate is different from service level. If a customer orders 1000 units, and their supplier can only provide 900 units of that order, their fill rate is 90%. In statistics, notably in queuing theory, service rate ...
Infinite fill rate for the part being produced: Economic order quantity; Demand is random, continuous replenishment: Base stock model; Demand varies over time: Dynamic lot size model; Several products produced on the same machine: Economic lot scheduling problem
Engineer-to-order (ETO) - (D>>P) Here, the product is designed and built to customer specifications; this approach is most common for large construction projects and one-off products, such as Formula 1 cars. Build-to-order (BTO); syn: Make-to-Order (MTO) - (D>P) Here, the product is based on a standard design, but component production and ...

In (), the first order loss function [(,)] captures the expected shortage quantity; its complement, [(,)], denotes the expected product quantity in stock at the end of the period. [ 10 ] On the basis of this cost function the determination of the optimal inventory level is a minimization problem.
