We consider a two-echelon single commodity inventory system with one warehouse(supplier) at the higher echelon and one retailer at the lower echelon. The retailer stocks individual items of a commodity and satisfies unit demands which occur according to a Poisson process.

Due to uncertainties in demand, some parts might go out of stock during the manufacturing process leading to backorders if an outof-stock part is critical. In order to reduce additional cost it is important to optimize restocking processes. To do so, the concept of Part Criticality is used to rank and prioritize parts involved in the production of different products. In this paper, we develop a...

A large empirical literature has reported that the futures market contains valuable information for explaining stock returns and that stock returns display signi ̄cant cross-correlations internationally. A parallel literature has recorded evidence that the distribution of stock returns is close to a mixture of normal distributions and that Markov switching models may therefore provide an adequat...
