Dynamic Routing of food items through a restaurant kitchen improves on advanced routing methods by being forward looking and forecasting the time to prepare each of the menu items within an order based on the current capacity and conditions of individual prep stations. Such Dynamic Routing has the ability to monitor for current status on a user defined basis, updating forecasted times based on real-time factors that can impact these forecasted times. The method improves on advanced routing methods by keeping track of the status of each and every individual item within an order as it goes through the preparation process.
