Abstract:
|
In this paper, a mathematical programming based model is described to assist with the schedule of services
for a set of auxiliary bus lines that operate alleviating a disruption of the regular transportation system during
a given time period. In contrast to other models, considered static, service schedules are set taking into
account demand fluctuations that may happen in that time period. Passenger flows are represented with a
multi-commodity structure and disseminate through paths on a diachronic capacitated network which lead
them to their destination in the shortest time taking into account the available capacities of the bus units. The
model permits to accommodate the schedules of the auxiliary bus lines in order to enhance transfers and to
minimize total travel time. The model assumes that operational times at bus stops are constant and that buses
do not queue at stops. The solution method can be considered an heuristic that combines searches along
subgradient's projected directions with a pattern search based method for constrained optimization. |
