Abstract

An electronic data structure, tangibly embodied in an electronic information carrier, models a manufacturing process, and a computer-implemented method that generates and that uses the data structure. The data structure includes a header structure comprising planned time duration information for a defined manufacturing operation of the manufacturing process. The data structure also includes a resource capacity requirement structure linked to the header structure. The resource capacity requirement structure includes, firstly, planned resource capacity requirement information for a defined resource used in the manufacturing operation, and secondly, planned time refinement information that defines, within the header time duration information, a further refined timeframe during which the defined resource is estimated to be consumed.
