most regions of iran are confronted with inadequate supply and excessive demand of water in agriculture sector mainly resulting from a high difference between water providing cost and its price. coping with such a challenge needs to determine the water price based on the economic principles and its value in agricultural production. the aim of this study was to determine the economic value of th...

  An optimal desirability function method is proposed to optimize multiple responses in multiple production scenarios, simultaneously. In dynamic environments, changes in production requirements in each condition create different production scenarios. Therefore, in multiple production scenarios like producing in several production lines with different technologies in a factory, various fitted r...

Intelligent well technology has provided facility for real time production control through use of subsurface instrumentation. Early detection of water production allows for a prompt remedial action. Effective water control requires the appropriate performance of individual devices in wells on maintaining the equilibrium between water and oil production over the entire field life. However, there...

Considering Iran geographical location, water is the most limited factor in agriculture section. Therefore, it would be logical to consider water as one of the most significant criteria in selection of cultivation model. The purpose of this study is assigning cultivation pattern based on economic value of water in Gotvand Township in agronomic year 2008-2009. So it was necessary to computes the...

Production scheduling, the problem of sequentially con guring a factory to meet forecasted demands, is a critical problem throughout the manufacturing industry. The requirement of maintaining product inventories in the face of unpredictable demand and stochastic factory output makes standard scheduling models, such as job-shop, inadequate. Currently applied algorithms, such as simulated anneali...

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...
