Due to the limitation of water renewable resources on one hand and increasing growth in consuming different parts such as agriculture, industry, urban, environment other hand, face management these valuable many challenges. Present study attempts clarify recent condition problem introduce effective tools supply sector. In order achieve this purpose, simulating model HEC-Res Sim was used for Dok...

The aim of this study is to evaluate the ability soft computing models including multilayer perceptron- (MLP-) water wave optimization (MLP-WWO), MLP-particle swarm (MLP-PSO), and MLP-genetic algorithm (MLP-GA), simulate daily monthly reference evapotranspiration (ET) at Aidoghmoush basin (Iran). Principal component analysis (PCA) was used find best input combination lagged ETs. According resul...

today, the country's banking system, according to the discussions to join the world trade organization is encountered with new challenges such as entry of foreign banks, emerging private banks and increasing the activities of financial and credit institutions. therefore, in order to survive and compete in this dynamic environment banking organizations require paying more attention to human...

In this paper, an interesting and easy method to solve the multi-dimensional  knapsack problem is presented. Although it belongs to the combinatorial optimization, but the proposed method belongs to the decision making field in mathematics. In order to, initially efficiency values for every item is calculated then items are ranked by using Multiple Criteria Decision Making (MCDA).  Finally, ite...

efficiency and effectiveness are two effective concepts in performance evaluation of each organization toward reaching to goals with minimum resource consumption. so, this research aims consideration of relationships between behavioral dimensions of job or that is called the topic of organizational behavior or psychology including job stress, job satisfaction, and job interest and job rotation ...

Prediction of highly non-linear behaviour of suspended sediment flow in rivers is of prime importance in environmental studies and watershed management. In this study, the predictive performance of artificial neural network (ANN) integrated with genetic algorithm (GA) was assessed. GA was used to optimize the parameters and architecture of the ANN. Five simulation scenarios (S1–S5) were develop...
