1. A method comprising:
executing a computational framework for valves of portions of equipment, wherein each of the valves is assigned a number, and wherein each of the portions is definable by a respective state selected from an at least one valve closed state, an all valves closed state, and an all valves open state;
checking valve states of the valves with respect to a workflow specification according to a checking order defined by the assigned numbers;
responsive to the checking of the valve states of the valves, identifying individual valves that are not in a corresponding valve state as indicated by the workflow specification; and
generating a sequence for changing the valve state of each of a number of the individual valves to its corresponding valve state for satisfying defined states of the portions.
