A business process simulation system for scheduling token arrival in a business process simulation is provided. The system includes a frequency module for receiving user input defining a frequency of token arrival; a duration module for receiving user input defining at least one repeatable valid duration of availability to receive tokens; an exemption module for receiving user input defining an exemption duration within the availability duration; and a timer module for receiving user input defining a recurring timer calendar for the business process simulation. The system also includes a token scheduling controller, wherein the token scheduling controller is adapted to process instructions corresponding to the user inputs and sending token scheduling instructions corresponding to the user-defined parameters to the business process simulation.
