TLDR
The vertex method can avoid abnormality due to the discretization technique on the variables domain and the widening of the resulting function value set due to multi-occurrence of variables in the functional expression by conventional interval analysis methods.About:

An extension to possibilistic linear programming
TL;DR: The method relies on α-cuts of the fuzzy number parameters to generate a succession of pairs of classical linear programs that produce a convex possibility distribution of the optimal objective values with the corresponding levels of the decision variables.
