ارائه متدی برای تعیین شرکتهای پیمانکاری ایمن با استفاده از روشهای یکسان سازی پروفایل کارایی فازی هر ورودی و تحلیل سلسله

  Background and Aims Health, Safety and Environment (HSE) performance measurement of the contractors and identification of the best ones can make a perception of the past changes in their HSE performance. Consequently, this may motivate them and provide an opportunity to improve their quality of services. The aim of this study is to rank the contractor-companies of one of the Iranian steel manufacturing companies considering their safety behavior and also to determine the best combination of contractors-companies.   Methods safety behavior sampling method used to determine the status of unsafe acts. The fuzzy efficiency numbers of each input were ranked by Chen & Klein method. To obtain a final ranking AHP was applied. The obtained rankings by FIEP-AHP were compared to the ranking of DEA.   Results Results indicated that the most frequent unsafe behaviors were related to not-using or miss-using the PPE, using broken tools and inappropriate working condition respectively. A significant relationship between experience, education and age with safety behaviors was obtained (p<0.05). Results showed that companies’ number 2 and 6 had respectively the best and worst ranks.   Conclusion Because FIEP increases the power of recognition especially when the number of DMUs is lower than inputs and outputs, it can be suggested as an appropriate model for determining the best contractor companies.
