چکیده
تحلیل قابلیت اطمینان سیستم‌های بزرگ، پیچیده و سرمایه‌بر مانند شیررلودر معادن زغال‌سنگ اهمیت بسیاری دارد، زیرا این سیستم‌ها نقش حیاتی در عملکرد ایمن و پایدار معادن دارند. در این تحقیق، از روش‌های درخت خطا و شبکه بیزین برای ارزیابی قابلیت اطمینان شیررلودر معدن زغال‌سنگ طبس استفاده شده است. درخت خطا با شناسایی ترکیب رویدادهای منجر به خرابی، ابزار مناسبی برای مدل‌سازی است، اما در ارزیابی وابستگی‌های پیچیده و احتمالات شرطی با محدودیت‌هایی مواجه است. برای رفع این محدودیت‌ها، درخت خطا به شبکه بیزین تبدیل شده است. شبکه بیزین با مدل‌سازی احتمالاتی روابط علّی-معلولی بین متغیرها، امکان تحلیل دقیق‌تر و به‌روزرسانی‌های احتمالات را فراهم می‌کند. در این مطالعه، ابتدا درخت خطای شیررلودر برای شناسایی عوامل مؤثر در خرابی طراحی شد و سپس با نگاشت به شبکه بیزین، مزایای این مدل گرافیکی در انعطاف‌پذیری و تحلیل حساسیت بررسی شد. در نهایت، با استفاده از معیار اهمیت برنبام، اجزای بحرانی سیستم شناسایی و رتبه‌بندی شدند. نتایج نشان داد زیرسیستم الکتریکی با ۴۰٪ بیشترین سهم را در خرابی‌های شیررلودر دارد. موتور درام پس از ۱۱۰ ساعت و کل سیستم پس از ۱۴ ساعت عملکرد، قابلیت اطمینان خود را از دست می‌دهند. بنابراین، نگهداری پیشگیرانه این اجزا نقش مهمی در کاهش خرابی و توقف سیستم دارد.ترکیب این روش‌ها به‌عنوان ابزاری توانمند می‌تواند در تحلیل و بهبود قابلیت اطمینان سیستم‌های مهندسی استفاده شود و به بهینه‌سازی عملیات نگهداری و کاهش خرابی‌ها کمک کند.

چکیده English

Reliability analysis of large, complex, and capital-intensive systems such as coal mine shearer loaders is of great importance because it ensures the safe and stable operation of these critical equipment in mines. In this regard, fault tree analysis and Bayesian network, have been considered. Fault tree, as a graphical tool, evaluates the reliability of the system by identifying the combination of events leading to failure; however, this method faces limitations in modeling probabilistic dependencies, complex relationships, and conditional probabilities. In order to overcome these limitations, fault tree has been transformed into Bayesian network. Bayesian network is a probabilistic graphical model that models the cause-effect relationships between variables in a probabilistic manner and allows for the consideration of uncertainties and complex dependencies. In this study, focusing on the Tabas coal mine shearer loader as one of the critical components in coal mines, first, its fault tree is presented to identify the factors affecting the failure. Then, by mapping this tree to the Bayesian network, advantages such as flexibility in updating probabilities, sensitivity analysis capability, and causal inference capability have been achieved. Finally, using the birnbaum importance measure, the critical components of the coal mine shearer loader were identified and ranked. The combination of fault tree and Bayesian network methods can be used as a powerful tool in comprehensive and accurate reliability analysis of engineering systems.
