An entire school timetabler, fast and reliable, for any school, college, university ... Schedules anything else: staff-exams-rooms or meetings, congresses, conferences, hospitals ...

Cannot build the complete weekly (monthly or module) timetable of the entire school ?
Are you tired and dizzy from the endless rotations of those hundreds or thousands of periods ?

- Enough with your migraines !

- Enough with working late into the night !

- Enough with your weeks of intellectual overload !

    Five times teacher friendly
We have more minimizing functions for teachers for the total number of: 1) gap⁺⁺ hours⁺ between working hours, 2) single hour working days⁺⁺⁺, 3) travels between locations (if your school has multiple locations). 4) not consecutive hours in the same day with the same activity and class (this is both teacher and student friendly). 5) Even more all these minimizes are done in accordance with the teachers' preferences. Solution = the whole school timetable (even with thousands of periods) complete up to last period. We generate millions of solutions in order to find the best one. This is extremely teacher friendly since nobody else do not achieve such highly results not even for one of these functions.

    ⁺ hours or periods : We call them hours, but periods can have any duration you need.
    ⁺⁺ gap hour : Sometimes one teacher must wait 4 hours between his 3 work-hours if for example he is scheduled to work only in the first, the fourth and the seventh hour. Instead of wasting time, this teacher prefers to work in a compact work-program of 3 hours without those 4 waiting hours or gap hours. Our VIOsystem will generate a complete timetable (with all teachers and classes) with a more compact work-program for each teacher, minimizing the total number of gap hours for teachers. Moreover, each class can have any work-program (with reserved gaps or not), except reserved gaps, each class will have zero (unwanted) gap hours.
    ⁺⁺⁺ single hour working days : Any timetabling process will schedule some teachers to work only one hour in a day and more hours in other days. Instead of going to work for only one hour in a day, these teachers prefers to work in a compact work-program of several hours daily without such single hour working days.

    All you need to know is Excel since all is in EXCEL
You don’t need training, practice or experience nor to use or to learn a new program. All is simplest, easiest, fastest, friendliest - without: button after button, window after window, menu after menu or stupid codes for teachers, activities (school subjects), classes (groups of students)... Your data are not confiscated and buried who knows where nor locked in a cursed database nor sliced and scattered behind long paths of buttons, windows and menus. Instead, your data and our results are entirely visible in Excel sheets. So with small or large amounts of data you can do: copy, paste, sort, filter, format... After all, your work and data are your property.

    We use only Modelino.xls data format
This file is an extremely efficient way to store or manipulate your data sheets and to verify if they correspond to educational plans. So, input your data into Modelino.xls and send us a copy (an example is on top). Then, with our powerful VIOsystem, we will build your complete timetable with the smallest number of gap⁺⁺ hours⁺ for teachers and without unwanted gap hours in the students’ program, missing data or overlapping. If your timetable changes from one week (month or module) to the next, we can generate others, as you need. We generate master and individual timetables for standard or class-oriented schools and not for modern or course-oriented schools because we schedule classes (groups of students) not individual students.

      NEWS    (June 2009)

    How can they be such liars?
We have tested other software with real data and the results are far from favorable: All generators manage to build less than 90% of the timetable losing more than 40 of the last periods. Those last periods are the most difficult part because the most conflicts arise for those closest to the end of the timetabling process. All other software claim that they can manage with lots of constraints, but they fail even without the teachers' preferences. All claim to be friendly and simple but use complicated databases only to confiscate your data and work.

    Minimizing the total number of not consecutive hours
We minimize the total number of not consecutive hours in the same day with the same activity and class (form). Therefore, it will be fewest situations in which for example for the same day and class between Chemistry hours are History or French hours.

    We can manage the access to different types of labs or resources    (July 2008)
E.g. 1) If you can not work in only 2 Chemistry Labs with 3 or more classes (forms) then we can limit to 2 the maximum number of chemistry periods that can be done simultaneously. In this way all chemistry periods can be done in Chemistry Labs. 2) If you can not have 4 or more classes in the Sports Arena then we can limit to 3 the maximum number of Sports periods that can be done simultaneously. In this way all Sports periods can be done in the Sports Arena. We can do the same for any other similar situations.

    Timetabling a school with multiple locations    (August 2007)
We can build the best timetable for a school with 2 or more buildings situated in different locations even if the teachers traveling from one location to another need some traveling time. With the same teacher friendly approach, we will minimize the total number of travels between different locations.
For example, if it is not possible to set a teacher to work only in one location per day (that means zero travels between locations) then we will set the first part of his working program in one location and the second in a second location leading to only one travel per day, and that for all teachers.

    No more single hour working days    (April 2006)
To build a more compact working-program for each teacher (minimizing the number of gap hours for teachers) leads to some single hour working days for some teachers. Removing them or building the timetable without them seems impossible. But now we can do it having two minimizing function one for the total number of gap hours for teachers and another for the total number of single hour working days. In almost all cases, these two functions will obtain the most compact working program that means zero for both total numbers.

    Beat that - if you can    (May 2005)
We generate solutions (conflict free and complete timetables up to the last period) even if each teacher has preferences and even more, we minimize the number of the gap periods for teachers. This means that each teacher will have a more compact working-program (each teacher will have to wait less until his/her next working period). If you have only a few teachers with preferences then all teachers can have zero gaps. As an average for difficult situations: half of your teachers will have each only one gap period (non working hour between working hours) inside his/her weekly working program, and the other half none.
  On the one hand, we generate complete timetables while others do not, and on the other hand, you can say that we have the best solutions for your teachers. Even more, it is all simple and convenient because we use the popular Excel tables both for data and results. So, with either small or large amounts of your data you can do whatever you want: copy, sort, filter, format, print, transfer, edit... And you can do the same with the timetables that we will generate for you.

    Outrunning the human brain    (July 2002)
As you know, the human brain is the most powerful computer and (after many years of practice) some humans become very skilled in timetabling. Even where those very skilled humans have failed to build at least one timetable, we build and compare thousands or millions of timetables in order to select the best one !

    Glad and proud to be the first    (August 2001)
The number of permutations (and each another possible timetable) for a timetable with only 1 class with 30 hours (periods) weekly, from which the activities are 2 with 4 hours, 4 with 3 hours and 5 with 2 hours, is N = 30! / 4! ² / 3! ⁴ / 2! ⁵ = 1.110408075747e+25 then for 10 similar classes is N¹⁰ = 2.849877000733e+250 and for 40 classes is N ⁴⁰ = 6.596361768566e+1001 . That means for 1, 10, 20, 30 or 40 classes, a number of possible timetables, with over 25, 250, 500, 750 respectively 1000 digits !!!
  One year has 31536000 seconds then only to count this permutations one PC at 10GHz, need 35210809 years for only 1 class (or 35210809 PCs need one year). Supplement this 35210809 with over 225 digits for 10 classes or over 975 digits for 40 classes to find out the number of years needed only to count all those possible timetables. But, in spite of this tremendous number of timetables, among them only few are solutions and therefore almost all are faulty, because, for example, one teacher can not teach in 2 classrooms in the same time, nor 4 hours of physics to one class in one day... Beside the number of timetables, the number of solutions is absurdly small, so small that you can not put it in words. And if it is for the 40 classes timetable, let's say with 600 digits smaller than the number of timetables, then from 1000 digits will remain 400 digits (10 ¹⁰⁰⁰ / 10 ⁶⁰⁰ = 10 ⁴⁰⁰) for the number of solutions. Then how to compare such lots of timetables from that enormous number of solutions in order to find the best one?
  Consequently, there are two insurmountable challenges. On the one hand, to find at least one solution - each solution is hidden between a tremendous number of faulty timetables (10 ⁶⁰⁰ = a number with 600 digits). On the other hand, to find the best solution (with the smallest total number of gap hours for teachers...), from an enormous number of solutions (10 ⁴⁰⁰ = a number with 400 digits).
  Therefore, we are glad and proud to be the first who come with a solution for such a tremendous and enormous problem.
