In this paper, we propose a new scale factor in differential evolution for optimization of numerical data (low dimensional data) that is both seen in algebraic and exponential form in real world scenarios. With the present work we improve the optimization of DE with real world numerical data set of the Lahi crop production of Pantnagar farm, G. B. Pant University of Agriculture and Technology, ...

for evaluation of efficiency and yield per surface unit with using the 56 sugar beet producer countries data in year 2005 an econometric model based on cols method has presented. with this model maximum sugar beet production efficiencies considering the harvested area and annual rainfall measure and level of mechanization has been determined. in total iran with production efficiency 0.43 is in ...

energy management is one of the main ways of the efficient use of energy resources. the prediction of crop yields based on energy inputs can help farmers and policymakers to estimate the level of production. required data for study were randomly collected from 70 broiler farms in north west of iran. the input energies were included human labour, machinery, fuel, feed and electricity and the out...

Production leveling (heijunka) is one of the lean tool that is used to stabilize a manufacturing system (reduce the bullwhip effect). Production leveling is a kind of cyclic scheduling that creates production regularity and coordination simplicity. This article describes simulation modeling and multivariate analysis of an assembly production line in a microelectronics factory. The assembly line...

sugar beet as an industrial crop plays a main role in satisfying domestic demand of sugar. study on the production efficiency of sugar beet is important because this is a factor that influences production without additional cost. in this study, data envelopment analysis approach (dea), was implemented to calculate technical, administrative and scale efficiency of sugar beet production. also opt...

Manuscript describes producing keratin hydrolysate from sheep wool through two-stage technology whose principle consists in first having wool processed in an alkaline environment during the first stage, and then effecting hydrolysis in the second stage through the action of proteolytic enzyme. Experiments were planned in accordance with factor schemes of 23 types in which factors under study we...

background: optimal allocation of resources commensurate with performance improvement is the concerns of all countries including iran. estimation hospitals production function is important in the economic management of hospitals. objective: the aim of this study was to estimate the production function of iranian selected public hospitals as well as analyze the economic behavior in use of hospit...
