The course timetable construction is a procedure that every academic department has to carry out at least twice annually, more times if some of the requirements change. These requirements indicate that a collection of elements must be taken in mind in order for an acceptable solution to be found. They come either from the inherent constraints of the problem or from the involved parties, namely ...

We identify the on-time performance as a key to evaluate a railway timetable’s robustness to disturbances and evaluate the on-time performance for two single services on the Swedish Southern Mainline for the autumn period 2011. We analyse the punctuality by studying how the performance develops en route. Typically the time spent in the stations is underestimated, which partly is compensated for...

In order to improve passenger service, a waiting cost function, weighting different types of waiting times and late arrivals, is designed and minimised. The approach is applied to a small part of the Belgian railway network. In the first phase of the approach, ideal buffer times are calculated to safeguard connections when the arriving train is late. These buffer times are based on the delay di...

This system demonstration presents an approach to interactive timetabling used by the UniTime university timetabling system. This application, which is publicly available under an open source license, has been successfully applied at Purdue University [8], a large public university (39,000 students) with a broad spectrum of programs at the undergraduate and graduate levels. The complete system ...

Detection of internal body time (BT) via a few-time-point assay has been a longstanding challenge in medicine, because BT information can be exploited to maximize potency and minimize toxicity during drug administration and thus will enable highly optimized medication. To address this challenge, we previously developed the concept, "molecular-timetable method," which was originally inspired by ...

One of the challenging heuristic problems is that how to generate an academic timetable. Many searching methods have already been applied to take care of the problem but yet some drawbacks exist. The drawbacks are commonly about the convergence, the speed, and the effectiveness of the algorithm. This paper aims to apply modified Particle Swarm Optimization (PSO) to give a better solution rather...
