this paper deals with a multi-period fixed charge production-distribution problem associated with backorder and inventories. the objective is to determine the size of the shipments from each supplier and backorder and inventories at each period, so that the total cost incurred during the entire period towards production, transportation, backorder and inventories is minimised. a 0-1 mixed intege...

The sound inventories of the world’s languages show a considerable extent of symmetry. It has been postulated that this symmetry is a reflection of the human physiological, cognitive and societal factors. There have been a large number of linguistically motivated studies in order to explain the selforganization of these inventories that arguably leads to the emergence of this symmetry. A few co...

We evaluate two leading explanations for inventories, the (S,s) and stockout avoidance motives, examining each within dynamic stochastic general equilibrium environments. We find that the (S,s) model is far more consistent with the cyclical behavior of aggregate inventories in the postwar U.S. when fluctuations arise from technology shocks, rather than preference shocks, while the converse is t...

We report an investigation into strategies, algorithms, and software tools for document image content extraction and inventory, that is, the location and measurement of regions containing handwriting, machine-printed text, photographs, blank space, etc. We have developed automatically trainable methods, adaptable to many kinds of documents represented as bilevel, greylevel, or color images, tha...

We study the role of inventories in explaining the decline in U.S. output volatility observed in recent years. Our analysis is motivated by two striking features in the data. First, as is commonly noted, output growth was more volatile than sales growth before 1984 but in recent years they have both become less volatile and about equally as volatile as each other. Second, the forecasting role o...

Groundwater irrigation has been instrumental in enhancing food security and, arguably, in mitigating poverty in developing countries. Groundwater provides timely irrigation, leading to an increase in crop intensity and productivity (Food and Agriculture Organization 2003). But groundwater irrigation also contributes the most to the depletion of groundwater reserves. Countries with significant g...

Groundwater from the coastal aquifers north of Chennai is being pumped since 1981 to meet the increasing demand. Huge groundwater extracting in the coastal aquifers groundwater causes lowering of groundwater table which led to seawater intrusion. The objective of this study is to assess the behavior of this aquifer to seawater intrusion under different hydrological stresses by groundwater model...
