Resumo: | ||||||||
Hazardous materials transportation has received considerable attention in the
last years. Many researchers have been developing mathematical models that
minimize the risk associated to this operation. The present work is based on
studies that focus routing techniques that minimize either the total distance, the
expected number of accidents (fatal or not fatal), the accident probability, the
residential population within a given distance from a route, or a mixture of these
parameters. They work with the assumption that a route should not be chosen if
the potential consequence incurred given that an accident occurs is high, even if
the route has a very low probability of an accident, or a low associated expected
consequence. For this reason, it is possible to observe that an important
characteristic of the hazardous materials routing problem is the existence of
multiple conflicting objectives. This means that a route that minimizes risk may
not coincide with a route that minimizes the truck operating cost, or with a route
that minimizes the risk imposed to special population categories. In this context,
this research presents a multiobjective model to the Hazardous Materials Routing
and also a specific solution methodology that determines routes that minimize the
accident risk with low probabilities, but with high consequences, including the
high cost affecting the environment and the population exposed. A number of
extensions and open issues are indicated for future research.
