We consider a decentralized two-period supply chain in which a manufacturer produces a product and sells it through a retailer facing a price-dependent demand. We assume that the secondperiod production cost declines linearly in the first-period production, but with a random learning rate. As the mean and/or the standard deviation of the learning rate increase, the traditional double marginaliz...

We consider the optimal control of an assemble-to-order (ATO) system with m components, a single end-product, and n customer classes. Demand from each class occurs continuously over time according to a Poisson process. Components are produced in separate production facilities, each with a finite production rate and exponentially distributed production times. Components can be stocked ahead of d...

The study aims to estimate an international reserves demand model for China using economic growth, propensity to import, real effective exchange rate and trade openness variables for quarterly period spanning from 1985Q1 to 2014Q4.The bounds testing technique to cointegration is used to test for a long run relationship, while the autoregressive distributed lag approach is used to estimate short...

The effective factors on the economic growth of Iran during the first 5-year development plan are studied. The main characteristics of this period are that the first development plan began after the end of war during which some of the unused capacities of the war period were utilized. While the budget deficit was continued in this period the government also pursued policies such as devaluation ...

Quorum sensing (QS) is a cell density-dependent mechanism which enables a population of bacteria to coordinate cooperative behaviors in response to the accumulation of self-produced autoinducer signals in their local environment. An emerging framework is that the adaptive significance of QS in the regulation of production of costly extracellular metabolites ("public goods") is to maintain the h...

We study the effects of different pricing strategies available to a continuous review inventory system with capacitated supply, which operates in a fluctuating environment. The system has a single server with exponential processing time. The inventory holding cost is nondecreasing and convex in the inventory level, the production cost is linear with no set-up cost. The potential customer demand...
