The risk assessment function is v(p,u,v), where p ∈0÷1 is an expert assessment of probability, u = 1,2,3,4,5 is an expert assessment of the consequences of the risk occurrence and v ∈0÷1 is an expert assessment of the risk vulnerability. In this matrix the assessment function v(p,u,v)= p.u.v

The four sectors of risk prevention priorities are set by expertly defined values of k, so that when p.u.v k the evaluation corresponds to a given priority and when p.u.v > k, it doesn’t. The k values are the same as for the matrix risk assessment.

Priority k

0 < Dispensable ≤ 0,4
0,4 < Low ≤ 1,2
1,2 < Middle ≤ 2,4
2,4 < High ≤ 4,95
