ABSTRACT:
A method of optimizing a manufacturing operation includes receiving as input data a description of a plurality of desired results of the operation, receiving as input data capabilities of a machine to accomplish the operation, determining an operation space including of a set of operations sufficient to accomplish all of the plurality of desired results using the machine capabilities, categorizing the operation space into groups, each group corresponding to one of the plurality of desired results, wherein any operation in the group sufficing to accomplish the corresponding one result, selecting a subset of the operation space, the subset comprising at least one representative from each of the groups, thereby making it sufficient to accomplish all of the plurality of desired results, and determining a short way to sequence the operations from the selected subset.
