Industries are one of the main sources of pollution in the world. Besides, the levels of energy resources consumption including water, electricity, and fossil fuel are very different among industries. On the other hand, Iranian government pays a large amount of energy subsidy to manufacturing units. Because of it, the government wants to know which of manufacturing industries are efficient, pro...
Water requirements in many large water supply systems are provided by mixing water withdrawal from surface and underground resources with different quantity and quality.Water supply from underground sources requires energy consumption and surface water resources are limited and unstable.The aim of this research is managing optimal supply of required water of system with minimum energy cost and ...
انرژی هسته ای یکی از منابعی است که نقش عمده ای در تولید برق ایفا می کند. تحلیل روند سطح تقاضا و منابع عرضه ی انرژی در جهان، توجه به روند تهی شدن منابع فسیلی در دهه های آینده و مزیت های زیست محیطی انرژی اتمی، از عواملی هستند که سبب شده اند تا انرژی هسته ای یکی از حامل های قابل دسترس و مطمئن انرژی در جهان به شمار رود. از این رو بررسی تأثیرات انرژی هسته ای بر رشد اقتصادی به منظور درک دلیل سرمایه گ...
Global warming, environmental pollution, fossil resources reduction, the increased demand and price of energy carriers, and various international social and political consequences are among the problems of traditional energy generation and distribution system. In the traditional generation systems, about two-thirds of energy is wasted and the presence of scattered energy resources such as photo...
