Patent ID: 8301274

Claim:
A method for managing product segments of product production rules within a manufacturing execution system adapted to provide a final product, the method applied as an algorithm implemented on a server with a database and comprising the steps of: a) associating each one of a plurality of sets of product segments within one of a set of product production rules that are stored in the database under a reference standard product production rule; b) inputting a command to the database for performing one of following selectable operations: i) add a new product segment; ii) remove a previous product segment; iii) replace a previous product segment with a new product segment; c) introducing a further set of new product production rules comprising previous product segments and a further product segment in the database; d) inserting an indicator related to operation (i, ii, iii) selected in step b) in the new product production rule; and e) performing an algebraic operation on all product segments of both the reference standard product production rule and the new product production rules, so that the algebraic operation delivers a final standard product production rule (PPR') resulting from one of the operations of adding i), removing ii), replacing iii) selected in step b).
