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

Table 5

Results of the network based on signed distance ranking index.

Paths	𝑑(𝐿𝑖,0)	Ranking
𝑃1: 1-2-4-6	70.25	3
𝑃2: 1-2-5-6	61.5	2
𝑃3: 1-3-5-6	58.5	1

Path 𝑃₃, that is 1-3-5-6, is the fuzzy shortest path since it has the minimum signed distance ranking index and the corresponding shortest path length is 𝐿₃.
