This new approach helps the senior managers make decisions in risk and accident management with stronger scientific support and more reliably.</span></span></em></p> Fuzzy rule based, Accident forecasting, Risk assessment,Safety analysis 53 64 http://ijiepr.iust.ac.ir/browse.php?a_code=A-10-62-3&slc_lang=en&sid=1 Gholam Reza Jalali Naieni 180031947532846001551 180031947532846001551 No Assistant Professor Industrial Engineering college, IUST Ahmad Makui amakui@iust.ac.ir 180031947532846001552 180031947532846001552 Yes Associate Professor Industrial Engineering college, IUST Rouzbeh Ghousi ghousi@iust.ac.ir 180031947532846001553 180031947532846001553 No PhD Student Industrial Engineering college, IUST
