Developing a straightforward approach for group decision making based on determining weights of decision makers

摘要: Abstract Group decision making is an active area of research within multiple attribute making. This paper assumes that all the makers (DMs) are not equally qualified to contribute equitably process. The aim this develop approach determine weights DMs, in which information on alternatives with respect attributes, provided by each DM, represented form interval data. We define average individual decisions as positive ideal (PID), and maximum separation from PID negative decision, characterized a matrix, respectively. weight DM determined according Euclidean distances between decisions. By using obtained aggregated into collective decision. Then ranked based Meanwhile, also gives humanized method optimistic coefficient, used adjusting relative importance profit risk. Finally, we give example illustrate developed approach.
