Currently, the only shortest-distance path is provided by commercial products where the current shortest path algorithms only support the single-objective decision model. However, path selection is a multiple criteria decision process. This book describes a multiobjective path optimisation (MOPO) model. Three single-objective path optimisation (SOPO) models, cumulative distance, passed intersections and number of turns, were taken into account to establish a...
