Extensive research has been devoted to economic production quantity (EPQ) problem. However, little atten-tion has been paid to problems where depreciation cost and process quality cost must be considered, simulta-neously. In this paper, we consider the economic production quantity model of minimizing the annual total cost subject to depreciation cost and process quality cost, where depreciation...

in this work the effect of the accuracy of a fae detonation modeling on the generated blast wave is investigated. first, a one-dimensional numerical simulation with a reduced chemical kinetics of c2h2-o2-ar, involving 25 elementary reactions, is used as the base model. the properties of the blast calculated with this model is compared with those of simpler models, the similarity solution of tay...

HPV vaccine has been recently added to the Iran Drug List, so decision makers need information beyond that available from RCTs to recommend funding for this vaccination. Modeling and economic studies have addressed some of those information needs. We reviewed cost effectiveness studies to find a suitable model for Iranian population to determine the potential cost effectiveness of HPV vaccine p...

Dynamic compaction is a soil improvement method which has been widely used for the increase of bearing capacity through stress wave propagation during heavy tamping. The cost and time of project implementation can be effectively curtailed by developing a model that can be used in the design of dynamic compaction operations. The numerical models offered so far are mostly one or two-dimensional, ...

The present study considers of the water and air flow and Micro-Bubble production inside the venturi tube, by the use of dimensional analysis. Numerical analysis of Micro-Bubble creation in venturi tube requires fast computers and large amounts of storage space. Up to now, there has been no numerical analysis concerning Micro-Bubble creation and all other existing studies are experimental. To s...

T he welfare cost of inflation in a new Keynesian model has been studied in this article. Nominal prices and wages are subjected to Rotenberg's adjustments in the benchmark model. In addition, this study uses the CIA model to compare the welfare cost of seigniorage tax and consumption tax. The model is calibrated for the Iranian economy and the results of the calibration are as follow...

Predicting and optimizing the performance of ray shooting is a very important problem in computer graphics due to the severe computational demands of ray tracing and other applications, e.g., radio propagation simulation. Aronov and Fortune were the first to guarantee an overall performance within a constant factor of optimal in the following model of computation: build a triangulation compatib...
