The optimization of value streams in manufacture will always present alternative solutions to planners as a result of the interdependencies between all the optimization parameters. In the search for an ideal value stream in terms of cost and benefit, relevant monetary and non-monetary parameters have to be considered. The method introduced describes a mathematical calculation bringing different parameters of a value stream into one equation. After a normalization step, and a systematic prioritization of the parameters, a value is calculated for each alternative solution. This value allows planners to compare alternatives and to find the best-case solution with the current state process.
