This paper considers a two-echelon capacitated supply chain with two non-identical retailers and information sharing. We characterize the optimal inventory policies. We also study the benefits of the optimal stock rationing policy over the first come first served (FCFS) and the modified echelon-stock rationing (MESR) policies. © 2006 Elsevier B.V.

In the article I present definitions of the concepts quality and quality assurance, which are basis for proposing a general definition of quality of word bases. The quality of word bases is the specifications that customer and producer agree upon, and includes linguistic and other user relevant considerations. This is exemplified with the revision work of a term record format, and work with a w...

Transshipment, the sharing of inventory among parties at the same echelon level of a supply chain, can be used to reduce costs. The effectiveness of transshipment is in part determined by the configuration of the transshipment network. We introduce chain configurations in transshipment settings, where every party is linked in one connected loop. Under simplifying assumptions we show analyticall...

We study when the operator f(Bw) is chaotic in the sense of Devaney on a Köthe echelon sequence space, where Bw is a weighted backward shift and f(z) = ∑∞ j=0 fjz j is a formal power series.

This paper, studies the coordination of two-echelon supply chains using a credit (delayed) payment option and/or a wholesale price discount offer. We develop models for optimizing individual members’, as well as supply chain’s objectives. These models lead to the determination of the retail price and the order quantity for the buyer, as well as the production batch size, wholesale discount and/...

In this paper we study the coordination of the two-echelon supply chain using credit and quantity discount options. We determine the retail price, order quantity for the buyer, and the setup frequency, credit period for the supplier in four different scenarios (with or without coordination and with or without credit option). And we suggest a policy that incorporates both quantity discount and c...

Vernonia galamensis Cass is a huge potential industrial crop with very high content of vernolic acid in the seed oil. The experiment was carried out to determine the effect of inter- and intra- row spacing on the yield and yield related traits of Vernonia galamensis Cas.The experiment was conducted for two years during 2014-2015 on experimental field of Wondo Genet Agricultural research center,...
