Each step may be associated with a component of the air separation plant (200), and may be associated with an ac - tion and a set of permissives corresponding to the action. The set of permissives for each action may specify one or more parameters for controlling the execution of the corresponding action. After retrieving the startup information (620), the system may automatic - ally initiate execution of the sequence of steps (630), and may monitor the execution of each of the steps (640). The system may de - termine (660), based on the monitoring, whether to modify a parameter specified by one of the permissives corresponding to an ex­ ecuted action.
