Method, system and computer product for controlling a manufacturing process

摘要

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.

1. A method for controlling a manufacturing process of a plant via a MES system, which comprises the steps of:
a) providing the MES system with a product definition model containing MES entities of different types for defining an exchange of information among the MES entities, wherein the MES entities contain at least one product-related entity; b) providing to the MES entities, associating methods for working with a given product definition of a given final material modeled according to the product definition model; c) within the product definition model, defining for the product-related entity a set of product-related entities referencing the product-related entity and each other via a nested structure, the product-related entity is hereinafter referred as a parent product-related entity and the set of product-related entities is hereinafter referred as a set of nested product-related entities; d) within the product definition model, defining for the product-related entity a set of product-related parameters to define information that may be sent to the MES system to control a plant manufacturing process of the given final material; e) within the product definition model, defining an additional entity called parameter exchange definition for providing a tool for defining how data of product-related parameters of the set of nested product-related entities and of the parent product related entity are to be exchanged among each other at run-time by the MES system; f) at engineering time, building a given product definition of the given final material by inserting the entities of steps c), d), e) and by specifying how the set of product-related parameters are exchanged; g) at run time, instantiating the entities of step f) into run-time production requests objects obtained by the given product definition; and h) at run time, controlling the plant manufacturing process by executing the production requests of step g).
