the aim this research is the diagnosis of production chains in oil’s regions of iran. for this reason, by using, input-output table for oil’s regions of iran,linkages and production chains are identified. the results of research indicate that although oil and natural gas sectors contain 50 percent of region’s output, but it is not a leading sector. in contrast, manufacturing of species of machi...

technological developments in various sectors and considering the speed and accuracy as an integral part of the decision-making process in the age of knowledge economy, has caused the disaster economy an important role in risk assessment and management in national and regional planning. the development of models used in this area, resulted in considering indirect consequences of disasters on th...

In this paper we do not attempt to develop an interregional model. Rather, we propose a mathematical structure of computational framework with which a family of interregional input-output models can be constructed. This family of interregional input-output models encompasses the well-known class of static models that are used to analyse the propagation of demand throughout an economic system di...
