Interval judgments are a way of handling preferential and informational imprecision inmulticriteria decision analysis (MCDA). In this article, we study the use of intervals in thesimple multiattribute rating technique (SMART) and SWING weighting methods. Wegeneralize the methods by allowing the reference attribute to be any attribute, not just themost or the least important one, and by allowing the decision maker to reply with intervalsto the weight ratio questions to account for his/her judgmental imprecision. We also studythe practical and procedural implications of using imprecision intervals in these methods.These include, for example, how to select the reference attribute to identify as manydominated alternatives as possible. Based on the results of a simulation study, we suggestguidelines for how to carry out the weighting process in practice. Computer support canbe used to make the process visual and interactive. We describe the WINPRE software forinterval SMART/SWING, preference assessment by imprecise ratio statements (PAIRS),and preference programming. The use of interval SMART/SWING is illustrated by ajob selection example.
