Occupational risk assessment with grey system theory [PDF]

open access: yesCentral European Journal of Operations Research, 2019
The article proposes a new method of occupational risk assessment which uses the grey decision model. The method is called the grey occupational risk assessment model (GORAM). The presented method allows for combining measurable and qualitative factors in the process of occupational risk assessment through the use of expert knowledge.
