چکیده

We present a periodic review inventory model with multiple delivery modes and demand forecast updates. We generalize the notion of the base-stock policy for inventory system with multiple delivery modes. While base-stock policies are optimal for one or two consecutive delivery modes, it is not so otherwise. For multiple consecutive delivery modes, we show that only the fastest two modes have optimal base stocks, and provide simple counter examples to show that the remaining ones do not. We investigate why the base-stock policy is or is not optimal in different situations.

Are Base-Stock Policies Optimal in Inventory Problems with Multiple Delivery Modes?

We present a periodic review inventory model with multiple delivery modes. While base-stock policies are optimal for one or two consecutive delivery modes, they are not so otherwise. For multiple consecutive delivery modes, we show that only the fastest two modes have optimal base stocks, and provide a simple counterexample to show that the remaining ones do not. We investigate why the base-sto...

Optimization of two-stage production/inventory systems under order base stock policy with advance demand information

It is important to share demand information among the members in supply chains. In recent years, production and inventory systems with advance demand information (ADI) have been discussed, where advance demand information means the information of demand which the decision maker obtains before the corresponding actual demand arrives. Appropriate production and inventory control using demand info...

A Periodic Review Inventory Model with Three Consecutive Delivery Modes and Forecast Updates

This paper is concerned with a periodic review inventory system with three consecutive delivery modes (fast, medium, and slow) and demand forecast updates. At the beginning of each period, the inventory level and demand information are updated, and decisions on how much to order using each of the three delivery modes are made. Both finite and infinite horizon problems are treated. Objectives co...

Queueing Inventory System in a Two-level Supply Chain with One-for-One Ordering Policy

Consider a two-level inventory system consisting of one supplier and one retailer. The retailer faces a Poisson demand with a known rate and applies base stock (one-for-one ordering) policy. That is, his inventory position is set to a pre-determined level, so the demand pattern is transferred exactly to the supplier. The supplier has an inventory system and a service unit with exponentially dis...

On Optimality of a Class of Dynamic Myopic Policies for Continuous-Time Replenishment with Periodic Updates

This paper is motivated by inventory problems arising in supply chains characterized by continuous replenishment programs based on information exchanged (reviewed) only intermittently between a manufacturing system (supplier) and a customer (retailer). When the replenishment is once-per-period, rather than at any point of time, a well-known result is the optimality of the so-called myopic base-...
