Measurability and Reproducibility in Timetabling Research: State-of-the-Art and Discussion

In this paper, we first illustrate the state-of-the-art in timeta- bling research w.r.t. two important research qualities, namely measura- bility and reproducibility, analyzing what we believe are the most impor- tant contributions in the literature. Secondly, we discuss some practices that, in our opinion, could contribute to the improvement on the two aforementioned qualities for future papers in timetabling research. For the sake of brevity, we restrict our scope to university timetabling problems (exams, courses, or events), and thus we left out other equally- important timetabling problems, such as for example high-school, em- ployee, and transportation timetabling.
