School timetable

A timetable governs the time-shifted access to scarce resources.

For example, the school curriculum, for which dates regulates (usually called school hours ) meet teacher and school class to which subjects. Knapp is both the time of teachers ( because almost every teacher teaches several classes that are next to part-time teachers or part-time employees are not freely available ) as well as the classes (because each class has multiple teachers). In addition, the availability of the rooms must be considered ( for example, specialized rooms such as gym, music room, chemistry lab, etc.). In addition, there may be additional requirements, such as the afternoon lessons must be distributed to the students.

Timetable problem can be mathematically formulated in the language of graph theory and provide a continuing difficult task for computer science dar.

Increasing the difficulty is a price system dar. Here there are no classes, but students of one or more grades are combined into courses that they can choose to some extent. The creator of the curriculum must lay the courses that the number of jumping lessons ( free lessons ) is minimized for the students.

In the vocational school students part-time education, which is offered either on a few days per week or more than week block have. Here the presence and absence of some pupils must be considered especially in the teacher plans.

The tabular presentation of the subjects in their temporal scheme is also referred to as the timetable. Usually, the time (beginning and end of a lesson ) is plotted in the first column, next day, the successive lessons. School timetables are mostly designed for repeat on a weekly basis and are usually a half.

Timetabling software supports the planner and the students in the preparation of timetables and representation plans. If a teacher is absent or a room used for another purpose, such a representation has to be planned. Modern software can make appropriate plans to the Internet.
