Abstract

The complexity of the problem grows as multiple individuals involved in the decision making process. Since each individual may have a different experience, attitudes, and knowledge, their approaches might be different from each other on the same problem. Therefore, more comprehensive techniques are needed in group decision making methods in order to determine how much a decision maker’s contribution is considered in the final solution (i.e., the weight of each decision maker). The purpose of this study is to determine the combined weights of decision makers based on both the objective weights, using the geometric cardinal consensus index, and the subjective weights provided by a supervisor. In order to represent the implementation of the method, the study includes a case study in a medical decision making. There are several anesthesia method alternatives to apply; specifically, general anesthesia, local anesthesia, and sedation, which are considered by surgeons. In the case study, the combined relative weights of the medical doctors are derived regarding this issue.
