Decision Representation Language (DRL) and Its Support Environment

Abstract

In this report, I describe a language, called Decision Representation Language (DRL), for representing the qualitative aspects of decision making processes such as the alternatives being evaluated, goals to satisfy, and the arguments evaluating the alternatives. Once a decision process is represented in this language, the system can provide a set of services that support people making the decision. These services, together with the interface such as the object and the different presentation formats, form the support environment for using the language. I describe the services that have been so far identified to be useful — the managements of dependency, plausibility, viewpoints, and precedents. I also discuss how this work on DRL is related to other studies on decision making.
