Abstract
A multiobjective model-based predictive control approach is presented for
solving a dial-a-ride problem. The dynamic objective function considers two
dimensions: user and operator costs. As those two components are usually aimed
at opposite goals, the problem is formulated and solved through multiobjective
model predictive control. When a new call asking for service is received, the
method first solves a multiobjective optimization problem, providing the Pareto
optimal set. Note that from this set just one solution has to be applied to the
system. Then, the dispatcher participates in the dynamic routing decisions by
expressing his/her preferences in a progressively interactive way, seeking the
best trade-off solution at each instant among the Pareto optimal set. The idea
is to provide to the dispatcher a more transparent tool for the decisions.
Several criteria, emulating different dispatchers, are proposed in order to
systematize different ways to use the information provided by the dynamic
optimal Pareto front. An illustrative experiment of the new approach through
simulation of the process is presented to show the potential benefits in the
operator cost and in the quality of service perceived by the users.
