A fast simulated annealing algorithm for the examination timetabling problem

Expert Systems With Applications, 2019
The timetabling problem involves the scheduling of a set of entities (e.g., lectures, exams, vehicles, or people) to a set of resources in a limited number of time slots, while satisfying a set of constraints.

Energy-efficient timetabling and rolling stock circulation planning based on automatic train operation levels for metro lines

Transportation Research Part C: Emerging Technologies, 2021
We investigate the energy-efficient train timetabling and rolling stock circulation planning problem for metro lines based on flexible selections of train operation levels, which involve running levels (various running times and speed profiles) and dwell

Integrated optimization of line planning and train timetabling in railway corridors with passengers' expected departure time interval

Computers & industrial engineering, 2021
Line planning and train timetabling are two basic problems in railway operations. A commonly used way is to first obtain the line plan and then design the train timetable based on the pre-generated line plan.

An Energy-Efficient Train Operation Approach by Integrating the Metro Timetabling and Eco-Driving

IEEE transactions on intelligent transportation systems (Print), 2020
Energy-efficient train operation is regarded as an effective way to reduce the operational cost and carbon emissions in metro systems. Reduction of the traction energy and increasing of the regenerative energy are two important ways for saving energy ...

A bi-criteria hybrid Genetic Algorithm with robustness objective for the course timetabling problem

Computers & Operations Research, 2018
Traditional methods of generating timetables may not yield robust solutions that may easily be adapted to changing inputs. Incorporating late changes by making minimum modifications is an important need in many practical applications of timetabling ...

TIMET TIMETAL 407

Alloy Digest, 2021
Abstract Timetal 407 (Ti407) is a wrought, heat-treatable, alpha–beta, Ti-V-Al-Si-Fe alloy that excels in applications requiring resistance to impact, explosive blast, and/or other forms of shock loading. Its properties are generally similar to those of Ti-6Al-4V or Ti-3Al- 2.5V; however, in comparison, Timetal 407 can provide ...

Integrated optimization of train stop planning and timetabling for commuter railways with an extended adaptive large neighborhood search metaheuristic approach

Transportation Research Part C: Emerging Technologies, 2020
Train stop plans and timetables play key roles in railway operation. Previous research has demonstrated that their integration can significantly improve the quality of a train timetable, especially for commuter railways with flexible service frequencies ...

A new model for automated examination timetabling

Annals of Operations Research, 2011
Automated examination timetabling has been addressed by a wide variety of methodologies and techniques over the last ten years or so. Many of the methods in this broad range of approaches have been evaluated on a collection of benchmark instances ...

Periodic Timetabling with Integrated Routing: Toward Applicable Approaches

Transportation Science, 2020
Periodic timetabling is an important, yet computationally challenging, problem in public transportation planning. The usual objective when designing a timetable is to minimize passenger travel time.

Social equity-based timetabling and ticket pricing for high-speed railways

, 2020
High-speed railways are expanding rapidly over the world, providing fast, convenient, and comfortable transport. It is therefore important to ensure that people are not excluded from high-speed railway use due to relatively high ticket prices.
