چکیده

بخش انرژی در جهان واقعی جزء پیچیده­‌ترین سیستم­‌هاست که بایستی بصورت یک دیدگاه کل­نگر واکاوی شود. محققین در این پژوهش به شناسایی و تحلیل تعاملات موثر بر خدمات پس از فروش در صنعت گاز مایع ایران(LPG) پرداخته‌­اند. از آنجا که خدمات پس از فروش را می توان بر اساس معیارهای مختلفی ارزیابی کرد، رویکرد تصمیم گیری چندمعیاره(MCDM)  برای چنین تحلیلی، رویکرد مناسبی است. با توجه به پیچیدگی خاص صنعت گاز مایع از مبادی پالایشگاهی تا رسیدن به دست مصرف کننده نهایی، در این تحقیق از DEMATEL FUZZY برای تحلیل تعاملات درونی استفاده و برای آنکه خواننده درک عمیق تری نسبت به موضوع پیدا کند از نمودارهای علی(CLD) در قالب پویا شناسی سیستم ها (SYSTEM DYNAMIC) بهره برداری می نماید. پس از مرور دقیق مبانی نظری و گرفتن نظر خبرگان، 17 شاخص موثر بر خدمات پس از فروش در این صنعت شناسایی و 10 خبره به سوالات پاسخ داده‌­اند. ضمن آنکه محققین تعاریف خاصی از خدمت را در این صنعت بیان می دارند. نتایج تحقیق نشان می­‌دهد که متغیرهای قابلیت اطمینان، نمایندگی­‌ها، اسناد و مدارک بیشترین تاثیرپذیری و متغیرهای بهبود، واکنش پذیری، زمانبندی بازدیدها بیشترین تعامل را با سایر مولفه­‌ها در مدل دارند. همچنین مدل داینامیک تصویر دنیای واقعی از تعاملات درونی خدمات را ترسیم می­‌کند.
