Incorporating wealth information into a multiple criteria decision making model

We describe how a multiple criteria decision making (MCDM) modelling framework can be extended to account for one of the behavioral ramifications of a decision making activity, namely, the decision maker's (DM's) perception of his/her current wealth status, referred to as decisional wealth. Within the MCDM framework, decisional wealth reflects the relative achievements of each of the objectives in a given efficient solution. It is our argument that a DM's preferences and the importance of his/her objectives, vary depending on the decisional wealth. Therefore, we use the wealth information and trade-off analysis to guide the search for preferred outcomes. We identify efficient solutions that satisfy a DM's wealth-dependent preferences, and we illustrate the proposed modelling framework with an example.
