چکیده

تحلیل پوششی داده ها ابزاری برای محاسبه کارایی در واحدهای تصمیم گیری از جمله زنجیره تأمین است. از آنجا که اخیراً مدل تحلیل پوششی دو مرحله ای تمرکز بیشتری روی فرآیندهای زنجیره تأمین در دو سطح داشته است؛ بدین منظور ضرورت ارزیابی زنجیره تأمین در سطوح بالاتر برای دستیابی به کارایی دقیق تر محسوس است. در این مقاله مدل وانگ(2010) را در سه سطح جهت ارزیابی یک زنجیره تأمین، گسترش داده ایم تا اهمیت یکپارچگی در کل زنجیره تأمین را نشان دهیم. در این مدل، تحلیل پوششی داده های دو مرحله ای کو و هوانگ(2010) با فرض بازده به مقیاس متغیر و کارایی مدل چن(2009) با در نظر گرفتن اهمیت نسبی وزن ها در هر مرحله به طور مجزا لحاظ شده است. مدل ارائه شده در یک مثال عددی اجرا گردیده و نتایج در قالب جداولی تحلیل گردیده است.

چکیده [English]

Data envelopment analysis is the tool for computation in decision-making units such as supply chain. Since the model of two-stage data envelopment analysis has more focused on supply chain processes in two levels; the evaluation in higher levels has been essential to obtain more accurate efficiency. This paper extends Wang & Chin (2010) model into three levels for evaluation the supply chain to show the importance of integration in the overall supply chain. The model is considered the extended two-stage DEA model of Koa and Hwang(2008) to variable returns to scale (VRS) assumption and the additive efficiency decomposition model of Chen (2009) generalized to take into account the relative importance weights of two individual stages. The presented model is executed in numerical illustration and the results are analyzed in tables.
