چکیده

انتخاب ماشین آلات یکی از تصمیمات مهم و پارامترهای اصلی طراحی معادن روباز می باشد که بر روی اقتصادی بودن عملیات معدن کاری تاثیر قابل ملاحظه ای دارد. در بیشتر فعالیت های معدن کاری، هزینه های بارگیری مواد یکی از اجزای اصلی هزینه های عملیاتی است و از این رو مسئله انتخاب ماشین آلات یکی از چالش ‌های اساسی مدیران معدن می باشد که پارامترها و معیارهای زیادی در آن نقش دارند. لذا در این تحقیق معیارهای میزان تولید روزانه، تعمیر و نگهداری، هزینه سرمایه ای ماشین، بهره‌برداری، مجموع هزینه های عملیاتی ماشین، مجموع پارامترهای عملیاتی، انعطاف‌پذیری، عمر مفید دستگاه، فضای کار مورد نیاز ماشین، عمر معدن، سیکل کاری ماشین به عنوان معیارهای مهم و اصلی در انتخاب ماشین بارگیری، در نظر گرفته شده اند. از این رو با مسئله انتخاب یک گزینه مناسب از بین گزینه های موجود (5 سیستم بارگیری)، بر اساس معیارهای موثر (12 معیار مذکور) مواجه هستیم که با استفاده از روش های تصمیم گیری چند شاخصه، ارزیابی ها و در نهایت انتخاب سیستم بارگیری مناسب را می توان به صورت علمی تر و قابل استناد و معتبر انجام داد. در این تحقیق از روش تحلیل تاکسونومی به عنوان یکی از مهم ترین روش های تصمیم گیری چند شاخصه برای انتخاب سیستم بارگیری مناسب در معدن سنگ آهن سنگان استفاده شده است. بر این اساس سیستم شاول هیدرولیکی و تراک به عنوان سیستم بارگیری مناسب معدن سنگان پیشنهاد و انتخاب شده است.

چکیده [English]

Nowadays attend to opportunities and threats in the industry and commerce and evaluation ability of industries and corporations envisage to existed risks and uncertainty is necessary and management of supply chain risks is very important. Management of risk is the process of identifying risks, assessment and scheduled for reduction of adverse effects. Risk assessment is one of the most important parts in risk management and according to the many risks and the need to expend optimize resource in the supply chain is very important. Risk assessment and ranking determined the superiority of risk based on relevant criteria and offered the opportunity to provide the appropriate response for each risk. In this paper whit present a comprehensive hierarchical model for risk assessment, identification of the main risks of supply chain based on the risk breakdown structure method and determination of measurements criteria, a comprehensive questionnaire was developed based on the relative importance of each risk in the steel supply chain and discuss the Esfahan Steel Company as a case study using taxonomy method as a multi-criteria decision making, is defined. Therefore, the risk associated with procurement and suppliers as the most critical risks identified in the company.
