چکیده

تولید به موقع تفکر و نگرشی نوین در اداره سازمانهای صنعتی است که اصول، روشها و تکنیکهای برخاسته از آن، حذف کامل و جامع اتلاف و افزایش بهره­وری را در تمامی فعالیتها اعم از داخل و خارج سازمان دنبال می­کند. بر همین اساس نیز هدف این تحقیق بررسی مقایسه­ای مولفه­های تولید به موقع در گروه­های مختلف صنعتی تبریز می­باشد. جامعه آماری این تحقیق شامل576 کارخانه در چهار صنعت ماشین آلات و تجهزات، مواد و محصولات شیمیایی، منسوجات و الکترونیک و وسایل مرتبط در اندازه­های کوچک و متوسط در شهر تبریز می­باشد. حجم نمونه با استفاده از تعیین رابطه در جامعه­های محدود 313 نفر تعیین شده است که به روش نمونه­گیری طبقه­ای نسبی این افراد مشخص شده­اند. برای جمع­آوری داده­ها از پرسشنامه و برای تجزیه و تحلیل داده­ها از تحلیل واریانس چند متغیره استفاده گردیده است. نتایج بررسی­ها نشان می­دهد که بین چهار صنعت در مؤلفه­های تولید ناب تفاوت وجود دارد.
