ملخص المقالة :
مدیران امروز سعی می کنند تا با استفاده از روش‌های علمی علاوه بر افزایش کیفیت محصولات، قیمت تمام شده آن را هم کاهش دهند. پایش وضعیت[1] یکی از فنونی است که در سال‌های اخیر مورد استقبال بیشتر مدیران صنعت قرار گرفته و البته منافع زیادی را هم عاید سازمان‌ها نموده است. تحلیل ارتعاشات[2] یکی از روش‌های پایش وضعیت است که با به کارگیری آن در صنعت به طور چشمگیری می‌توان از دوباره کاری ها جلوگیری نمود و هزینه‌های یک شرکت تولیدی را کاهش داد. برای نشان دادن تأثیر این فن در بهبود کارایی فرآیند تولید، شرکت صنایع چوب و کاغذ مازندران به عنوان مطالعه موردی انتخاب شده و نحوه‌ی استفاده صحیح از سیستم پایش وضعیت از طریق تحلیل ارتعاشات مورد بررسی قرار گرفته است. در این تحقیق مشخص شده است که چگونه می‌توان با آگاهی به موقع از خرابی‌های دستگاه‌ها و اعمال تعمیرات پیشگیرانه جلوی زیان قبل از وقوع گرفته شود و ثانیاً در مصرف قطعات و وقت نیروی انسانی در نگهداری و تعمیر ماشین‌آلات صرفه جویی شده و در نهایت سازمان به سمت بهبود کارایی هدایت شود.
