By setting criteria, we steer the AI engine to compose the schedule according to our wishes. Different organizations have different priorities for what a good schedule is. For example, some may not care for the minimal_day_rest as much as for nonstop_workdays_less/more.
A badly set criteria table may lead to funny and useless results. So one must be careful setting those criteria.
There are 12 stages for the criteria-weights. On the image below is displayed, the interactive bar-chart through which you will be setting the weight hierarchy:
The red line denotes the default value for each criterion.
The black bar denotes the value that is currently in use.
The grey bar is interactive. You use it to arrange a new hierarchy of weights.
The button System Default resets the settings to the absolute default. (The red lines)
Change the values by clicking on the column with the desired value for that criterion (0-12).
