چکیده مقاله :
هدف این مقاله ارزیابی عملکرد زنجیره تأمین چهار مرحله‌ای در حضور داده های غیرقابل کنترل، نامطلوب و منفی، در صنعت سیمان است. برای این منظور، مدل(SBM) Slack-Based Measure در تحلیل پوششی داده‌های شبکه ای ارائه شده تا عملکرد این گونه زنجیره‌ها را مورد ارزیابی قرار دهد. در ادامه، 42 شرکت سیمان حاضر در بورس و اوراق بهادار که زنجیرۀ متناظر هر یک از آن ها دارای چهار مرحله ی تأمین کننده، تولیدکننده، توزیع کننده و مشتری می باشد، طی دوره 1396-1394 مورد ارزیابی قرار گرفتند. بر اساس اجرای مدل، 5 شرکت در سه سال متوالی کارا و نمره کارایی مابقی آن ها در همه سال‌ها یا برخی از سال‌ها کمتر از 1 شده است.
The purpose of this paper is to evaluate the performance of a four-stage supply chain in the presence of uncontrollable, undesirable and negative data in the cement industry. For this purpose, the Slack-Based Measure (SBM) model in network data envelopment analysis is presented to evaluate the performance of such chains. Then, 42 cement companies present in the stock exchange and securities, the corresponding chain of each of which has four stages of supplier, producer, distributor and customer, were evaluated during the period 1394-1394. Based on the implementation of the model, 5 companies have been efficient for three consecutive years and the efficiency score of the rest of them has been less than 1 in all years or some years.
