Abstract: | A number of approaches for multi-attribute selection decisions exist, each with certain
advantages and disadvantages. One method that has recently been developed, called the
hypothetical equivalents and inequivalents method (HEIM) supports a decision maker
(DM) by implicitly determining the importances a DM places on attributes using a series
of simple preference statements. In this and other multi-attribute selection methods, establishing
consistent preferences is critical in order for a DM to be confident in his/her
decision and its validity. In this paper, a general preference consistency method is developed,
which is used to ensure that a consistent preference structure exists for a given DM.
The method is demonstrated as part of HEIM, but is generalizable to any cardinal or
ordinal preference structure, where the preferences can be over alternatives or attributes.
These structures play an important role in making selection decisions in engineering
design including selecting design concepts, materials, manufacturing processes, and configurations,
among others. The theoretical foundations of the method are developed and
the need for consistent preferences is illustrated in the application to a drill selection
case study where the decision maker expresses inconsistent preferences.
