Abstract:
A method for controlling a quality of a product during product manufacturing, wherein the manufacturing includes a plurality of modular manufacturing processes, each process among the plurality of modular manufacturing processes having an assigned value setting a process target output, the method comprising the steps of:i) in a database: (a) assigning to said product a predetermined criteria with respect to a performance of said product; (b) linking said performance to a feature of at least one structural element of the product, (c) associating said feature of said at least one structural element with at least one stage in one of said modular manufacturing processes which forms said at least one structural element, ii) measuring an actual process output of said one of said modular manufacturing processes, and iii) using said database if said actual process output deviates from a respective assigned value of said one of said modular manufacturing processes, reassigning the assigned value of at least one target output of a succeeding process among the plurality of processes in accordance with said actual process output or in accordance with said deviation thereby to reoptimise for variables in said database following said deviating of said process output, wherein the plurality of processes are controlled by a modular process control and said database comprises logical links between said variables.
