We study a joint inventory and pricing problem in a single-stage system with a positive lead time. We consider both additive and multiplicative demand forms. This problem is, in general, intractable due to its computational complexity. We develop a simple heuristic that resolves this issue. The heuristic involves a myopic pricing policy that generates each period’s price as a function of the in...

The purpose of this study was twofold. Firstly, it attempted to investigate whether language learning strategies (LLSs) can predict foreign language (FL) proficiency. Secondly, it examined what kind of LLSs Iranian learners of English use more frequently in FL institutes. To do so, 112 intermediate Iranian EFL learners participated in the study. Oxford’s Strategy Inventory for Language Learning...

though privileges ascribed to various facets of language learning strategy training have long been espoused with regard to varied language skills and components, the role some individual variables such as emotional intelligence might play in this respect seems to have received very scant attention. the researchers in the current study embarked on a probe into the impact of metacognitive strateg...

In teaching and learning process of English, the teacher should manage both students temperament language strategies since those have contribution to students’ achievements along with purposes education. The objectives this research are (1) investigate is there any correlation between characteristics speaking skill; (2) strategy inventory for (3) skill. This was employed by quantitative approac...

We consider the inventory transshipment problem between two retailers that sell the same product to two independent markets. One assumption that distinguishes our work is that unsatisfied customers may also switch to the retailer with surplus inventory. We examine the impact of such customer switching behavior on firms' inventory decisions and profits. We identify situations when the firm with ...

In this paper, we study a make-to-stock manufacturing system where two firms compete through dynamic pricing and inventory control. Our goal is to address competition (in particular a duopoly setting) together with the presence of demand uncertainty. We consider a dynamic setting where multiple products share production capacity. We introduce a demand-based fluid model where the demand is a lin...

The importance of manufacturing strategy (MS) has never been questioned and has been emphasized in many theoretical concepts, frameworks, and models. There are only a few empirical studies, however, which examine whether these theories work in practice. In this paper the hypothesis that the existence of MS contributes to company level competitiveness (ROS, inventory turnover) is tested. The stu...

The present study investigated the relationship between Iranian EFL learners' beliefs about language learning and language learning strategy use. A sample of 104 B.A and M.A Iranian EFL learners majoring in English participated in this study. Three instruments, the Michigan Test of English Language Proficiency (MTELP), Beliefs about Language Learning Inventory (BALLI), and the Strategy Inventor...
