tailieunhanh - A fuzzy data envelopment analysis based on credibility theory for estimating road safety

In this paper, the road safety performance of Iranian provinces is studied. To evaluate road safety efficiency scores, data envelopment analysis based on road safety (DEARS) method in two deterministic and non-deterministic situations is used. | Nội dung Text A fuzzy data envelopment analysis based on credibility theory for estimating road safety Decision Science Letters 8 2019 275 284 Contents lists available at GrowingScience Decision Science Letters homepage dsl A fuzzy data envelopment analysis based on credibility theory for estimating road safety Mohaddeseh Aminia Rahim Dabbagha and Hashem Omrania aFaculty of Industrial Engineering Urmia University of Technology Urmia Iran CHRONICLE ABSTRACT Article history Road accidents as a global challenge imposing irreparable financial and human life losses in Received December 2 2018 almost all countries especially in developing countries annually. According to world health Received in revised format organization WHO if this trend continues road accidents will become the 7th cause of human December 20 2018 death by 2030. Thus road safety policy makers have been trying to use safety promotion and Accepted January 4 2019 Available online preventative actions. In this paper the road safety performance of Iranian provinces is studied. January 5 2019 To evaluate road safety efficiency scores data envelopment analysis based on road safety DEA- Keywords RS method in two deterministic and non-deterministic situations is used. To consider the Road safety uncertainty in input and output data this paper develops credibility DEA-RS CreDEA-RS Data envelopment analysis based model. In fact the constraints of DEA-RS model are considered as credibility constraints and a road safety counterpart credibility DEA-RS CreDEA-RS model is proposed for evaluating road safety of Fuzzy sets provinces of Iran. According to the results provinces located in mountainous and forest areas Credibility theory such as Gilan had a much weaker performance than provinces in desert areas such as Yazd. 2018 by the authors licensee Growing Science Canada. 1.
