Hazmats Transportation Network Design Model with Emergency Response under Complex Fuzzy Environment

Algorithm 1

Procedure: priority-based encoding.

Begin: put in food source 𝐹_𝑖

        for 𝑘=1 to 𝐾

          let 𝑋_𝑘=𝐹_𝑖𝑘, 𝑛=0, 𝑃_𝑘←{𝑠(𝑘)}, 𝜂=𝑠(𝑘), 𝑋_𝑘(𝜂)=0

          while (𝑛<𝑁) do

         if (𝜂=𝑡(𝑘))

        break;

         else

        𝐽={𝑗∣𝑗∈𝑉 and (𝜂,𝑗)∈𝐴}, 𝛾=argmax_𝑗∈𝐽{𝑋_𝑖𝑗}, 𝑃_𝑘←{𝑃_𝑘,𝛾};

        𝑛=𝑛+1, 𝑋_𝑘(𝑗)=0, 𝜂=𝛾;

         end if

          end while

        end for

End: put out the complete path 𝑃_𝑘
