The method of imprecision (Wood & Antonsson, 1989) is a design method whereby a multi-objective design problem is resolved by maximizing the overall degree of designer preference: values are selected iteratively based on combining the degree of preference placed on them. Consider, however, design problems which exhibit multiple uncertainty forms. In addition to degrees of preference (imprecision) there are probabilistic uncertainties caused by, for example, measuring and fabrication limitations. There are also parameters which can take on any value possible within a specified range, such as a manufacturing or tuning adjustment. Finally, there may be parameters which must necessarily satisfy all values within the range over which they vary, such as a horsepower requirement over a motor's different speeds. This paper will present a method to define a `best' set of design parameters for such multiple uncertainty forms and requirements.
