چکیده

Exploitation of decorative rock mines are expeditiously rising due to various advantages such as being costeffective, nimble and simple processing, easy transportation, and satisfactory consuming market. As a thriving industry, mining operations are necessary to be planned systematicaly in terms of engineering and optimization approaches so that maximum profit is acquired through minimum utilization of resources. By applying the multi-objective linear programming model to the operations in Chaypareh-Khoy marble mine, this study provides optimized solutions for reducing energy and manpower cost while increasing profit. The model also features a fuzzy constraint to formulate the nondeterministic nature of available subsidized fuel. The developed approach results in a comprehensive operation and exploitation plan, which determines the optimum amount of extraction regarding different products, working shifts, fuel consumption amount, and the miximum earned profit. Finally, sensitivity analysis is done to investigate the effect of different objective functions on the model.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
