Two new approaches for the bi-objective shortest path with a fuzzy objective applied to HAZMAT transportation.

J Hazard Mater 2019 08 20;375:96-106. Epub 2019 Apr 20.

DIBRIS, Department of Informatics, Bioengineering, Robotics and Systems Engineering, University of Genova, Genoa 16145, Italy. Electronic address:

This work proposes two algorithms to the Bi-objective Shortest Path (BSP) problem, considering a fuzzy objective. Such approaches originally extend two classic label setting algorithms to solve BSP, in particular, the first one using a modified Gandibleux revision of Martin's algorithm and the second one based on the A* algorithm acceleration technique. The proposed extensions differ from the previous classic approaches for two main aspects: the two methods solve BSP problems with a linear objective function and a min-max objective function; the max-min objective considered in the BSP is a fuzzy objective function.
