Weightings

When the software is unable to schedule large numbers of periods, it makes sense to call up the weighting dialogue again and to determine if the setting 'extremely important' (5) is strictly necessary in all of the cases. In order to resolve an input weakness, it is often sufficient to reduce the setting of one or two items by one level to 'very important' (4) (see also the chapter 'General notes' under 'Weighting' above).

Increase the percentage of the periods to be scheduled until you are certain that all the input weaknesses have been resolved.

Use the more complex optimisation strategies only when you are certain that all entries are correct.

An important tool for the identification and location of input errors and violations of conditions are the 'Diagnosis' and 'Overall Diagnosis'tools. These are described in the following chapter.
