Interval optimization, or Frequency optimization, lets you automatically create Tasks that need to be executed a specified number of times during a pre-set period. This feature is available on both optimization engines.

For example, suppose you have some Tasks that need to be executed 4 times, others 2 times, and the rest once a month. Instead of creating copies of the Tasks for each execution, you can specify the Task frequency in your import file. The frequency is defined in the frequency column, like in the example below:

It is important to specify the date range during which these Tasks occur. You can predetermine any desired date range and the frequency of Tasks within it. The example above illustrates a range of one month, however, you can set any date range.

The main use case of this feature is to import and pre-plan Tasks that occur multiple times during a specific period. For example, suppose you're a delivery business that delivers to clients several times a month or a field service business that visits the same locations multiple times a month. Importing these Tasks might become time-consuming and tedious. This import functionality allows you to add those Tasks to eLogii quickly and efficiently and pre-plan your operations in advance once Tasks are uploaded.

You can allow only specific weekdays on which Tasks can be executed by populating the allowedWeekDays column with the desired day name (Mon, Tue, Wed, Thu, Fri, Sat, Sun). You can specify one day or multiple days as comma-separated values. This option will influence the number of Tasks created from frequency import based on the following logic:

When you set up a date range along with specific allowed weekdays, eLogii will automatically break that range down into weekly groups. Each group contains only the dates that fall on your chosen weekdays within that week.

For example:

The system will return three separate arrays, one for each week in the range, with only the matching dates included. Based on this range, Tasks for the following dates will be created:

Interval optimization can only be done within the Weekly planning view, which means that Weekly planning is a mandatory feature to have Interval optimization available.
To perform interval optimization, switch your view from Daily to Weekly by clicking on the view option switch located on the top bar of the app, next to the Date Picker. This will take you to the Weekly planning view.

Next, select the date range you would like to view on the screen (by default, the view is going to show a one week range), and click on the arrow on the Optimization button and select Interval optimization.

The engine will optimize your Tasks for the specified intervals and will honor any allowed weekday restrictions that were imposed.

The Task interval Optimization behavior can be adjusted in Configuration ⇒ Optimization ⇒ Task interval optimization.

It's possible to do the following:
