The collection of solid waste is a highly discernible and important municipal service. Despite
this fact, municipalities still make use of ine ective measures that are costly to sustain. The
basic nature of our problem is that of a Capacitated Arc Routing Problem with Vehicle
Site Dependencies. We present a Vehicle Decomposition Algorithm capable of determining
the collection routes and the vehicle
eet size and composition for a
eet of waste collection
vehicles with the objective of minimising the total cost incurred. Each vehicle class within the
eet may be constrained from traversing or servicing certain street segments due to limitations
such as physical dimensions. A sensitivity analysis is performed to determine the optimal
parameter values for use in the algorithm. The Vehicle Decomposition Algorithm is tested on
three example problems and results are presented.
