Stock allocation in general multi - echelon distribution systems with ( R , S ) order - up - to - policies

In this paper we analyze stock allocation policies in general N-echelon distribution systems, where it is allowed to hold stock at all levels in the network. The goal is to achieve differentiated target customer service levels (fill rates). Various allocation rules and accompanying numerical methods that have already been developed for smaller networks are extended and compared in an extensive ...

Routing and Inventory Allocation Policies in Multi-Echelon Distribution Systems

Two echelon-two indenture extended warranty distribution network under imperfect preventive maintenance policies

Nowadays, offering extended warranty is considered as a lucrative source of income from the perspective of the after-sale service providers. Meanwhile, the main concern is presence or absence of base warranty and strategies adopted by the manufacturer during this period. Moreover, extended warranty structure must be responsive and customer oriented, which not only control the services cost but ...

A multi-item multi-echelon inventory system with quantity-based order consolidation

The efficient management of a distribution system requires coordination between transportation planning and inventory control. Small and frequent shipments can reduce inventory levels while maintaining high customer service levels, but they increase unit transportation costs due to inappropriate utilization of the vehicles and more handling costs. On the other hand shipment consolidation polici...

Multi-Echelon Production/Inventory Systems: Optimal Policies, Heuristics, and Algorithms

The theory on multi-echelon production/inventory systems is a core theory within supply chain management. It provides useful insights for design of supply chains and may be used for tactical and operational planning decisions. The multi-echelon theory started with the seminal paper of Clark and Scarf in 1960. In this tutorial, we describe for which systems optimal policies are known, which key ...
