چکیده مقاله :
امروزه مدیریت دارایی های فیزیکی یکی از شاخه های مهم دانش و فناوری به شمار می رود. کاهش خرابی های اتفاقی و تعمیرات ناخواسته یکی از مهم ترین اهداف استفاده کنندگان از تجهیزات و ماشین آلات پیشرفته می باشد. در این میان تعمیرات مبتنی بر پایش وضعیت به عنوان راهکاری چاره ساز در مهار مشکلات فنی، اقتصادی و مدیریت راهبردی ماشین آلات و تجهیزات به کار برده می شود.در این تحقیق ضمن تشریح مبانی پایش وضعیت (CM) و استانداردهای موجود در این زمینه، روند تأثیرگذاری شاخص های موثر پایش وضعیت بر افزایش "قابلیت دسترسی تجهیزات" در سطح شرکت سهامی ذوب آهن اصفهان مورد بررسی قرارگرفته است و با استفاده از روش ترکیبی AHP - QFD، استراتژی های پایش وضعیت به منظور افزایش قابلیت دسترسی تجهیزات اولویت بندی شود. بدین صورت که اطلاعات مربوط به ماتریس خانه کیفیت را از طریق توزیع پرسشنامه طیف لیکرت بین مدیران و متخصصان بخش نگهداری و تعمیرات شرکت سهامی ذوب آهن اصفهان جمع آوری شد. یافته ها نشان دهنده آن است که استراتژی های تحلیل فرکانس و کل سطح ارتعاش با وزن2810/0 و استراتژی کلیدهای مغناطیسی و فیلترها با وزن 1026/0 به ترتیب بیشترین تاثیر را در افزایش قابلیت دسترسی تجهیزات دارند.
Nowadays management of physical assets is considered as one of the important fields of science and technology. Reduction of undesirable random failures and repairs is one of the most important objectives of those who utilize advanced types of equipment and machinery. Meanwhile, Condition Based Maintenance (CBM) has been recognized as an effective solution for the problems of technical, economic and strategic management of machinery and types of equipment. In this study, besides explaining the basics of this condition monitoring (CM) and existing standards, The influencing trend of CM process parameters on "increased equipment availability" have been studied in Isfahan Steel Company and, CM strategies have been prioritized using an integrated approach of Analytic Hierarchy Process (AHP) and Quality Function Deployment (QFD) towards improvement of equipment availability. Data related to house of quality is also via Likert questionnaire, have been collected between managers and experts of THE Maintenance department in the Isfahan Steel Company. The findings indicate that strategies of frequency analysis and overall vibration level with a total weight of 0.2810 and strategies of magnetic keys and filters with a total weight of 0.1026 have the most influence on increasing the availability of the equipment.
