We address the value of information (VOI) and value of centralized control (VCC) in the context of a two–echelon, serial supply chain with one retailer and one supplier that provides a single perishable product to consumers. Our analysis is relevant for managing slow moving perishable products with fixed lot sizes and expiration dates of a week or less. We evaluate two supply chain structures. ...

We examine the impact of RFID-point of sale data sharing on ordering decisions in a two-echelon supply chain. Theoretical studies have shown that accessibility to point of sale data can impact supply chain dynamics. We study this phenomenon from a behavior examination in the content of a simple, serial supply chain that is subject to stochastic demand and information time-lags using a controlle...

Multi-echelon distribution systems are quite common in supply-chain and logistic systems. They are used by public administrations in their transportation and traffic planning strategies as well as by companies to model their distribution systems. In the literature, most of the studies address issues related to the movement of flows throughout the system from their origins to their final destina...

This paper examines the beneficial impact of information sharing in multi-echelon supply chains. We compare a traditional supply chain, in which only the first stage in the chain observes end consumer demand and upstream stages have to base their forecasts on incoming orders, with an information enriched supply chain where customer demand data (e.g. EPOS data) is shared throughout the chain. Tw...

One of the key objectives of an optimised supply chain is to maintain a low operation cost as well as the service quality at a satisfactory level under demand uncertainty. However, the supply chain network design and inventory control optimisation are usually conducted in a sequential manner where the supply chain network is first determined by solving a mixed-integer programing (MIP) problem, ...

We address the value of information (VOI) sharing in the context of a two–echelon, serial supply chain with one retailer and one supplier that provides a single perishable product to consumers. We evaluate information sharing under two supply chain structures where the retailer shares it inventory level and replenishment policy with the supplier. In the first structure, referred to as Decentral...

Supply chain is complex today. Multi-echelon, highly disjointed, and geographically spread are some of the cornerstones of today’s supply chain. All these together with different governmental policies and human behavior make it almost impossible to probe incidents and trace events in case of supply chain disruptions. In effect, an end-to-end supply chain, from the most basic raw material to the...

This paper presents a study of a coordinated production inventory-system. In the proposed model, any echelon considers its successors as part of its inventory system and generates the replenishment order on the basis of operational information of its partners. We show that the coordinated decision making allows elimination of information distortion along the chain. Furthermore, we show how the ...

We explore coordination issues of a two-echelon supply chain, consisting of a distributor and a retailer. The effect of revenue-sharing contract mechanism is examined under stock-time-pricesensitive demand rate. First, we investigate relationships between distributor and retailer under noncooperative distributor-Stackelberg games. Thenwe establish analytically that revenue sharing contact is ab...
