Simulation takes the availability of resources into account during the simulation. Using a shift calendar, you can define when human resources and technical resources will be available for the execution of functions. For example, there are specific working hours (= active times) for human resources. Outside of these times, that is, during breaks, public holidays and vacation, they are not available (= inactive times).
A resource can only process a function if the resource is available, that is, after a process folder has reached the function and can begin orientation or processing. If the resource is not available, orientation/processing must wait until it is available, that is, until the corresponding time as defined in the shift calendar has been reached and providing the resource does not have to process other functions first.
For the simulation run, the times for which the resource is available are calculated using the Calendar event object in the Schedule model. In order to use the Schedule model as a shift calendar, it must be assigned to human resources or technical resources. The assignment is possible in event-driven process chains, function allocation diagrams, organizational charts and BPMN process diagrams.
