- Abstract:
-
Risk decisions are usually influenced by subjective and objective factors. During the process of decision-making, decisions are based not only on the objective risk but also on the subjective activity of decision-makers. In order to introduce decision-makers’ subjective attitudes to risk, a model of utility-based three-way decisions (UTWD) was produced by extending the risk function to a utility function. The monotonic relationships between the utility and probabilities of objects in three regions were investigated systematically. The computational methods for positive region utility, boundary region utility, and negative region utility are also given. Finally, an example is given to substantiate the conceptual arguments. The model is an extension of three-way decisions and provides a beneficial investigation into subjective risk measures in three-way decision research.
