Business Rules on Schedule Management

The business rules of the “Schedule” group are automatically applied at the time they are saved to the flights created in the system that match the criteria (flight number, performance period, etc.). This changes the configuration of the flight, so it is necessary to be especially careful when creating business rules that concern the operational flights. When saving a rule, a list of flights the configuration of which will be changed as a result of saving the rule is displayed in an individual preview window. If there are several rules in the system having different parameters and suitable for the same flights, then the rule with the highest weight shall be applied to the flight.

If changes are made to the flight parameters supported by business rules, then when the schedule is saved, the corresponding new business rules with the greatest weight are automatically created for the specific flight number.

If, while saving the rules, previously created rules with the same weight are found for the same flights, but with different parameters, and criteria of these rules conflict (that is, they cannot be simultaneously applied to flights), then in the preview the rules conflicting to the created ones are displayed. If a new rule is saved that conflicts to one of the previously created ones, the last created rule will be saved in the system, and the old one will be deleted.

At the time of creation, the created business rules of the “Schedules” group that suit the criteria for the created flight are automatically applied to new flights; however, if values different from the ones set by the rules are manually set for a new flight, they are prioritized higher and saved, only if the values specified by the business rules were not set by default by clicking the “Rules” button in the flight creation form.

In some cases, it is required to adjust the schedule, affecting several periods of the schedule at the same time. The AVP parameter - Adjustment validity period. Schedule changes are applied for the period covered by the AVP parameter. It is important to remember that the AVP cannot contain the performance frequency once per two weeks and past dates. Moreover, if the departure frequency criterion is not specified in the original business rule, then the AVP may not contain a frequency choice.
