The Hospitals / Residents problem with Couples (hrc) models the allocation of intending junior doctors to hospitals where couples are allowed to submit joint preference lists over pairs of (typically geographically close) hospitals. It is known that a stable matching need not exist, so we consider min bp hrc, the problem of finding a matching that admits the minimum number of blocking pairs (i.e.,...
The Vehicle routing problem of oil supply is characteristic of many constraints and complicated factors. In the paper, the Constraint Programming model of oil supply Vehicle routing problem is designed by NCL, and the heuristic arithmetic based on two phase optimization is designed by POEM. At last, the model and heuristic arithmetic are validated by an example and the satisfying result is gained.
In the SESAR traffic growth predictions, traffic complexity will become an issue that the current Air Traffic Management organization is not able to handle. The 4D trajectory concept offers new perspectives for deconflicting the traffic by ground-holding aircraft before they take-off. This paper studies the possible complexity reduction achievable by optimizing the aircraft take-off times. Therefore...
Travel time reliability is of great importance for evaluating the service level of public transit. If service level is expected to effectively improve, the travel time reliability must be enhanced. This paper proposed a novel model for setting up bus lane in urban area with the constraint of travel time reliability. The objective function is to minimize the setting up fare of bus lane. This model...
Chaku-Chaku production lines are currently widely adopted in manufacturing and assembly industry, which are an effective and efficient production organizational type thanks to its flexibility as well as customer-oriented flow layouts. However, due to the variation of customers' demand and unpredictable market factors, the layout as well as manpower allocation are both facing to be adjusted to satisfy...
TDRS (Tracking and Data Relay Satellite) can be seen as a bridge between user spacecrafts and ground station. The TDRSS (Tracking and Data Relay Satellite System) single access link scheduling problem is an important application field of TDRSS. The important character of the scheduling problem lies in that there is time windows constraint between TDRS and user spacecrafts. Tasks can be completed only...
