    I have a choice of four positions to place two prototype pieces of equipment to compare with two pieces of the current equipment design in the other two positions. Two of the four pieces of equipment are fed by one feed line and the other two are fed by another. Variability can be seen in all four positions; noise factor are normally random in nature but for some noise factors there has been a defined trend that could skew the overall results.
    Equipment positions are not easily changed but if able would like a design that allows me one position change for each piece of equipment; two changes and three changes to reduce overall error?

    Have you drawn a layout chart, also called physical process flow chart? It’s a scale map of the physical layout of the production area with flow arrows of the various materials/information moving between the machines/workstations. We typically use it to find ways to more efficiently organize the production area. It should provide insight into where to locate your prototype equipment. And, of course, you want to map it all out before you start moving equipment.
