Method for managing product segments of product production rules

Abstract

A main aim of present invention is to provide an effective method for managing product segments of product production rules within a manufacturing execution system adapted for providing a final product like the previous car to be manufactured, according to following steps: a) each one of a plurality of sets of product segments are associated within one of a set of product production rules which are stored in a database under a reference standard product production rule ; b) a command is inputted to the database for performing one of following selectable operations: i) adding; ii) removing; iii) replacing; c) a further set of new product production rules comprising previous product segments and a further product segment are introduced in said database; d) an indicator related to the selected operation (i, ii, iii) is inserted in said new product production rule, e) an algebraic operation is performed on all product segments of both said reference standard product production rule and said new product production rules, so that said algebraic operation delivers a final standard product production rule resulting from one of the selected operations of adding i), removing ii), replacing iii).

Description

technical field [0001] The invention relates to a method according to claim 1 for managing product segmentation of product production rules. Background technique [0002] In the field of process automation and process monitoring, there are standard automation systems for controlling the largest possible variety of machines and plants in the prior art. Such technology covers Siemens Corp in particular in the field of Manufacturing Execution Systems (MES) A wide range of products offered under the product family. A broad product line for solving the technical tasks in question such as counting, measuring, positioning, motion control, closed-loop control and cam control enhances the operational performance of suitable process controllers. Various configurations enable flexible machine concepts. [0003] In this context, there is a wide range of IT solutions to connect the actual hardware close to the technical and / or logical process with the client application layer that dr...

AI Technical Summary

Problems solved by technology

A large amount of basic information (in terms of modifying product segments) that does not depend exactly on a specific part of a product variant can also lead to the introduction of duplicate PPRs, which are absolutely useless in further MES

So unfortunately, a lot of database storage would be required, which might also make the further manufacturing process slower

In addition, there is a risk of losing local implementations in the event of unforeseen memory allocation failures

And if erroneous data needs to be corrected by searching for possible faults, it also means that operators in such unsafe situations have to manually check the validity of the data

So this is absolutely not safe and requires a very high level of knowledge of the database as well as a very long time, which is really very inconvenient in a production line
