sub basin prioritization is one of the integrated watershed management and sustainable development strategies. to protect natural resources, through marking zones of potential damage in small areas for is a primary need sustainable development. degradation potential zones project for watershed protection measures is not cost-effective economically. so this is a prerequisite for sub basin priori...

this paper considers the fuzzy inventory model for deteriorating items for power demand under fully backlogged conditions. we define various factors which are affecting the inventory cost by using the shortage costs. an intention of this paper is to study the inventory modelling through fuzzy environment. inventory parameters, such as holding cost, shortage cost, purchasing cost and deteriorati...

numerous parameters influence bit selection process, which considering all them is not normally feasible. existing methods use limited number of these parameters to choose a suitable bit for a specific drilling condition. one of the widely used methods is cost per foot. specific energy and drilling strength are another methods currently used for bit selection. different methods of bit selection...

The interpretation of the six cost parameters depends on the kind of Inspection envisaged; i.e. whether Inspection is a consumer's receiving inspection; a producer's inspection of finished goods, or "Internal inspection" by delivery of goods from one department to another within the same firm. The cost parameters may have quite different values when considered exclusively from a producer's or a...

One of the primary assumptions in most optimal pricing methods is that the production cost is a non-increasing function of lot-size. This assumption does not hold for many real-world applications since the cost of unit production may have non-increasing trend up to a certain level and then it starts to increase for many reasons such as an increase in wages, depreciation, etc. Moreover, the prod...

As an interconnection network, hypercube topology offers certain advantages such as high data bandwidth and low message latency to achieve computational efficiency. However, a significant drawback of this topology is that the number of ports per node increases with the number of nodes. In addition, in many applications not all the links are used equally frequently, and links on certain dimensio...

We discuss a nite element method based on the mixed least-squares formulation. The cost functional turns out to be a polynomial so that its gradient and Hessian can be computed eeciently. A multi-level Newton iteration is introduced for minimizing the cost functional that can converge from a rough initial guess. Error estimates are derived which not only are optimal in certain connguration, but...
