This study is an attempt to investigate the role of incidental and intentional vocabulary acquisition in addition to the influence of language learning strategy: namely, the use of vocabulary strategy by Iranian EFL learners in learning new vocabularies. Accordingly, this study is two-faceted. First, Part A examines the difference between different modes of presentation, incidental and intentio...

Manufacturers and wholesalers are increasingly cost conscious in response to today’s hyper-competitive environment. Lateral transshipment (LT) has been proposed as a viable solution to drive total inventory costs down whilst increasing customer service level. Our study proposes five LT decision rules with a case-based roadmap to guide professional inventory management. Results of this large fas...

In this paper a demand time series is analysed to support Make-To-Stock (MTS) and Make-To-Order (MTO) production decisions. Using a purely MTS production strategy based on the given demand can lead to unnecessarily high inventory levels thus it is necessary to identify likely MTO episodes. This research proposes a novel outlier detection algorithm based on special density measures. We divide th...

We consider a production control problem in a manufacturing system with failure-prone machines and a constant demand rate. The objective is to minimise a discounted inventory holding and backlog cost over an infinite planning horizon. The availability of the machines is improved through a corrective maintenance strategy. The decision variables are the production and the machine repair rates, wh...

In this paper, we propose a mathematical model in stochastic dynamic optimization form to determine the optimal strategy for an integrated single product inventory control problem and supplier selection problem where the demand and purchasing cost parameters are random. For each time period, by using the proposed model, we decide the optimal supplier and calculate the optimal product volume pur...

The construction and evaluation of a new self-report depression inventory was presented. Altogether 833 subjects participated in the various phases of the study. A sequential item selection strategy resulted in an inventory that provided separate scores for ten subscales: Sad Mood, Fatigue, Learned Helplessness, Guilt, Pessimism, Social Introversion, Irritability, Instrumental Helplessness, Low...

waste is a by-product of our daily activities, which poses a serious threat to societies all over the world. in this study, life cycle assessment (lca) methodology was used to determine municipal solid waste (msw) management strategy for minna, niger state, nigeria. three scenarios were modelled as alternatives to the current waste management system in minna. the baseline scenario was the exist...

We consider multi-echelon supply chains, typically consisting of retailer, distributor, manufacturer, etc. The inventory of each actor is subject to its own delay in delivery time, and each chooses its own inventory replenishment strategy. We model this interaction with a system of linear differential delay equations. When put in matrix form the system is triangular and we derive an exact solut...

In many practical situations the coordination of transportation management and inventory management may lead to considerable cost reductions. Transportation management includes the application of different types of shipment consolidation policies. Shipment consolidation takes into account the logistics strategy of combining two or more shipment orders to optimize transportation. When the shipme...
