Background and Objectives: A blood distribution network orchestrates distribution of safe blood products to hospitals. Blood shortage and blood wastage are two important factors which may affect efficiency of blood distribution network. Service delivery time is another factor that refers to the time interval between blood request by a hospital and transfusing it to the patient....

nowadays, congestion management is one of the major tasks accomplished by system operators to warrant the operation of transmission system within operating limits. this has resulted in unanticipated congestion interfaces in regional transmission systems. the system is, however, unable to evolve at a rate which is required to meet the quickly changing demand of competitive markets. to make the m...

  Abstract: In this paper, Artificial Neural Network (ANN) was used for modeling the nonlinear structure of a debutanizer column in a refinery gas process plant. The actual input-output data of the system were measured in order to be used for system identification based on root mean square error (RMSE) minimization approach. It was shown that the designed recurrent neural network is able to pr...

this research aims to apply a model to the study and analysis of environmental and natural resource costs created in supply chains of goods and services produced in thailand, and propose indicators for environmental problem management, caused by goods and services production, based on concepts of sustainable production and consumer behavior. the research showed that the highest environmental co...

In this work, the ability of Artificial Neural Network or ANN based on back-propagation algorithm to modeling and predicting of compressibility factor of natural gas has been investigated. The MSE analysis based on results, are used to verifying the suggested approach. Results show, a good agreement between experimental data and ANN predictions. An important feature of the model is its needless...
