Method, system and computer product for controlling a manufacturing process

A method and a system control a manufacturing process. The method includes providing an MES system with a product definition model having at least one product-related entity. Define for one product-related entity a set of product-related entities referencing the one product-related entity and each other via a nested structure. Define for each product-related entity a set of product-related parameters to define the information that may be sent to the MES system. Within the product definition model, define an additional entity called parameter exchange definition for providing a tool for defining how data of product-related parameters of nested product-related entities and of the parent product related entity are to be exchanged among each other. At engineering time, build the given product definition of the given final material by inserting the entities. At run time, instantiating the entities into run-time production requests objects obtained by the given product definition.
