Method, system and computer readable medium for managing design updates in a manufacturing execution system

摘要

In a method and a system for managing product definition updates for controlling a manufacturing process via a MES system, design information entities each defining manufacturing specifications for a specific product and including sets of data concerning different manufacturing steps are downloaded to the MES system. At the first download, first and second MES information entities are created and stored. The first entities have associated second entities each including data for a manufacturing step and include links to the associated second entities. At each update of a design information entity, a differential package including the whole of the data for a set having undergone changes and for newly added sets, and an identification for unchanged sets, is downloaded. A new version of the second entities corresponding to sets having undergone changes and/or additional second entities corresponding to sets of data that have been added are created and stored.

1. A method for managing product definition updates for controlling a manufacturing process via a manufacturing execution system (MES system), which comprises the steps of:
a) downloading from an external engineering environment to the MES system design information entities each defining manufacturing specifications for a specific product and including sets of data concerning different manufacturing steps, the design information entities and the sets of data being updated whenever the manufacturing specifications for the specific product change and being downloaded to the MES system at creation and at each update entailing MES-relevant changes; b) creating within the MES system, at a first download of a design information entity, first and second MES information entities where each first MES information entity has associated second MES information entities each including data for a manufacturing step for the specific product, creating the second MES information entities as versioned entities, the creating step including:
b1) creating a new version of the second MES information entities at each download of an updated corresponding design information entity and storing the second MES information entities with their data into a database of the second MES information entities;b2) creating a new version of the first MES information entity at each download of the updated corresponding design information entity by including into the first MES information entity, for each second MES information entity associated thereto, a link to the second MES information entity in the database; andb3) storing the first MES information entities into a database of the first entities; performing at each of the updates of the design information entity, the further following steps of: c) downloading a differential package including a whole of the data for a set having undergone changes and for newly added sets, and an identification of unchanged sets; d) creating and storing into the database a new version of the second MES information entities corresponding to sets having undergone changes and/or additional second MES information entities corresponding to sets of data that have been added, while maintaining existing versions of the second MES information entities for reuse by different versions of the corresponding first MES information entity or by different first entities; and e) creating the new version of the first MES information entity by:
e1) replacing, for an updated second MES information entity, the link to an existing version of the entity by a link to the new version thereof;e2) adding links to newly created second MES information entities; ande3) deleting links to second MES information entities corresponding to sets of data deleted from a design information entity.
