Asynchronous teams for solving the loading and routing auto-carrier problem

Orientador: Prof. Dr. Cláudio Nogueira de Meneses / Dissertação (mestrado) - Universidade Federal do ABC, Programa de Pós-Graduação em Ciência da Computação, 2016. / Beyond a complex real world system composed by a set of sophisticated machines and
qualied human resources distributed around manufacturing environment, the Auto In-
dustry needs a little more to allow their products to reach the nal costumers. Loading
vehicles like cars, trucks and vans into auto-carriers and designing routes to delivery sub-
sets of vehicles to auto dealers according to their orders are relevant tasks in automotive
value chain performed by transportation companies. Given the set of complex constraints
related to diferent vehicle models (with diferent dimensions) to be feasibly loaded into
dierent auto-carrier models plus the auto-carrier
eet routing task, transportation com-
panies must explore strong computational alternatives to address this optimization prob-
lem. In fact, we explore in this dissertation a real world complex problem composed by
two sub-problems, both belonging to NP-hard class: routing and loading. After formally
dening the tackled problem, we adopt, in this dissertation, a previously studied procedure
based on enumeration techniques for loading task and we propose an alternative approach
employing Asynchronous Teams concept, which combines local search algorithms in order
to cooperate to each other to try to resolve the routing sub-problem. Setting the results
provided by our implementation of Iterated Local Search (ILS) approach (already proposed
in literature for solving the routing sub-problem) as benchmark, we propose computational
experiments considering real-world instances, to compare performance of ILS to ve vari-
ants of our Asynchronous Teams implementations. Final results evidence the power of
this proposed alternative approach for founding quality solutions and its
exibility to easily
assume diferent configurations.
