Fuzzy Shortest Path Problem Based on Level 𝜆-Triangular LR Fuzzy Numbers

Algorithm 2

  Step 1 and Step 2 are same as in the Algorithm 1.

  Step 3: Calculate the level 𝜆-triangular LR mean and centroid index for each possible path lengths 𝐿_𝑖,

      using Definition 7.

  Step 4: The path having the minimum level 𝜆-triangular LR mean and centroid index is

     identified as the shortest path and the corresponding path length is the shortest path length.
