Controlling a manufacturing process

A method of controlling manufacturing processes in a plant via a MES system comprises the step (10) of providing the MES system with product definition information, including production-related information entities (100; 101...104) containing information on how to manufacture a product, and resource-related information entities (200, 300) containing information about resources to be used for manufacturing that product. The step of providing the MES system with product definition information includes: - providing the MES system (10) with a single production-related information entity for manufacturing a plurality of products whose manufacturing processes share most of the process workflow and most of the resources; and the step (10) of providing the MES system with a single production-related information entity includes: a) storing in said single production-related entity (11), for a non-shared resource, a label defining said non-shared resource as a generic resource; b) solving the generic resource into an actual resource (12) by creating a bind to a resource-related information entity (200, 300) at the creation of a production order for a specific product.
