چکیده

تحلیل پوششی داده­ها یک تکنیک ناپارامتری بر مبنای برنامه­ریزی ریاضی برای ارزیابی عملکرد واحدهای تصمیم­گیرنده متجانس است. بسیاری از واحدها ساختار چندمرحله ای دارند که در آن خروجی یک مرحله به عنوان ورودی مرحله بعدی است. یک زنجیره تأمین، که شامل چندین عضو مانند تأمین کننده و تولیدکننده می­باشد، فرایند چندمرحله ای دارد. در این مقاله، برای نخستین­بار، روش­های شبکه­ای برای دستیابی به بیشترین میزان بهره­وری در زنجیره­های تأمین، که به صورت یک سیستم چندمرحله ای در نظر گرفته می­شوند، معرفی می­شود. مدل­های پیشنهادی با نگاه به ساختار درونی زنجیره تأمین ارتباط بین مراحل سازنده آن را لحاظ می­کند. چنین دیدگاهی مفاهیم مدیریتی را در جهت بهبود کارایی زنجیره تأمین و نیز بهره­وری هر عضو آن ارائه می­دهد.

چکیده [English]

Abstract: Data envelopment analysis (DEA) is a nonparametric technique based on mathematical programming to evaluate performance of homogenous decision-making units (DMUs). Many DMUs have network structure where the output of one stage is the input to the next stage. A supply chain, which consists of several members such as supplier, manufacturer and customer, has multi-stage process. In this paper we, for the first time, introduce network DEA approaches to obtain the most productivity in a supply chain as a multi-stage DMU. Our models, by looking inside the internal structure of supply chain, consider the intermediate links between the stages. This perspective proposes managerial implications to improve the overall performance of a supply chain and the productivity of each member.
