the immiscible displacement of oil by water through a porous and permeable reservoir rock can be described by the use of a fractional flow curves (fw versus sw). water flooding project parameters can be obtained from the fractional flow curve. however, developing a representative fractional flow curve for a specific reservoir can be quite challenging when fluid and special core analysis data is...

while conventional data envelopment analysis models set targets separately for each decision making unit, centralized recourse allocation model is presented where there is a centralized decision maker that supervises all the operating units. optimizing of total input consumption and total output production is the main aim of this model. in this paper, firstly the centralized output production m...

environmental impact assessment is an important approach to achieve sustainable development. this study has investigated the environmental impact of sugar beet production. in addition data envelopment analysis was applied for detecting efficient units and decrease environmental impacts. in this study final environmental index of impact category consist of global warming, acidification, eutrophi...

evaluation of corporate performance has been one of the main issues in managing decision making. nowadays, evaluation of the suppliers is a completely strategic process because organizations rarely change their suppliers. thesuppliers also do their best to remain stable in the loop of supply chain. hence, it is important to evaluate the suppliers and not something to be done once at a time. it ...

different research and theoretical approaches have been adopted in the study of the space of music production. the space of production and consumption of culture in iran as a country in transition is diverse and heterogeneous. such a diversity and heterogeneity in itself causes problems for this space. the problem of this space, which in this research work has been defined as a small social spa...

this paper describes two data analysis techniques adopted in a decision support system (dss), decline curve estimation and artificial neural network (ann) approaches, which aid users in predicting oil production of a field. the system generates different predictions, according to scenario, chosen for prediction. these two approaches show that to explain production of a field, ann method shows b...
