Abstract

In recent years, the group ranking problem has become an important subject of study. In most group ranking problems, the focus is on identifying consensuses. No previous research has involved identifying conflicting opinions, called conflict patterns in this paper, among decision-makers. We define conflict patterns as orderings of alternatives that have roughly the same numbers of advantages and disadvantages. Conflict patterns can reveal the ranking of which alternatives are the most controversial among decision-makers and who the supporters and opponents are. Using conflict pattern data, decision-makers can communicate with people with differing opinions and attempt to resolve the differences.
