Decision Support by Interval SMART/SWING - Incorporating Imprecision in the SMART and SWING Methods
نویسندگان
چکیده
Interval judgments are a way of handling preferential and informational imprecision in multicriteria decision analysis (MCDA). In this article, we study the use of intervals in the simple multiattribute rating technique (SMART) and SWING weighting methods. We generalize the methods by allowing the reference attribute to be any attribute, not just the most or the least important one, and by allowing the decision maker to reply with intervals to the weight ratio questions to account for his/her judgmental imprecision. We also study the practical and procedural implications of using imprecision intervals in these methods. These include, for example, how to select the reference attribute to identify as many dominated alternatives as possible. Based on the results of a simulation study, we suggest guidelines for how to carry out the weighting process in practice. Computer support can be used to make the process visual and interactive. We describe the WINPRE software for interval SMART/SWING, preference assessment by imprecise ratio statements (PAIRS), and preference programming. The use of interval SMART/SWING is illustrated by a job selection example. Subject Areas: Decision Support Systems, Imprecision, Multicriteria Decision Making, and Uncertainty Modeling.

Decision support by interval SMART/SWING – methods to incorporate uncertainty into multiattribute analysis
Interval judgments are a way of handling preferential and informational uncertainty in multicriteria decision analysis. In this paper, we study the use of intervals in SMART and SWING weighting methods. We generalize the methods in three ways: (i) the reference attribute is allowed to be any attribute, not just the most or least important one, (ii) the decision maker can reply with intervals to...

متن کاملElderly Daily Activity-Based Mood Quality Estimation Using Decision-Making Methods and Smart Facilities (Smart Home, Smart Wristband, and Smartphone)
Due to the growth of the aging phenomenon, the use of intelligent systems technology to monitor daily activities, which leads to a reduction in the costs for health care of the elderly, has received much attention. Considering that each person's daily activities are related to his/her moods, thus, the relationship can be modeled using intelligent decision-making algorithms such as machine learn...
