A Sample-Based Method for Perishable Good Inventory Control with a Service Level Constraint
This paper studies the computation of order up to levels for a stochastic programming inventory problem of a perishable product. Finding a solution is a challenge as the problem enhances a perishable product, fixed ordering cost and non-stationary stochastic demand with a service level constraint. An earlier study [6] derived order-up-to values via an MILP approximation. We consider a computati...
متن کاملInventory Policies for a Make-to-Order System with a Perishable Component and Fixed Ordering Cost
We consider a make-to-order production system where two major components, one nonperishable (referred to as part 1) and one perishable (part 2), are needed to fulfill a customer order. In each period, replenishment decisions for both parts need to be made jointly before demand is realized and a fixed ordering cost is incurred for the nonperishable part. We show that a simple (sn, S1 n , S 2 n) ...
متن کاملA good approximation of the inventory level in a (Q, r) perishable inventory system
– This paper derives a good approach to approximating the expected inventory level per unit time for the continuous review perishable inventory system. Three existing approximation approaches are examined and compared with the proposed approach. Three stockout cases, including the full backorder, the partial backorder, and the full lost sales cases, which customers or material users generally u...
متن کاملA two-commodity perishable inventory system
We present a two-commodity perishable stochastic inventory system under continuous review at a service facility with a finite waiting room. The maximum storage capacity for the i–th item is fixed as Si (i = 1, 2). We assume that a demand for the i–th commodity is of unit size. The arrival instants of customers to the service station constitutes a Poisson process with parameter λ. The customer d...
