Multiple Criteria Decision Methods in Informatics Olympiads

Multiple Criteria Decision Making (MCDM) is applied in a variety of areas, including education. Informatics Olympiads, problem solving contests for high school students, is the area where MCDM methods can also be applied. The case of the Lithuanian Informatics Olympiad is analysed in this paper. There are several aspects occuring while maintaining the contest that requires decision making. The work of each contestant is evaluated in terms of several criteria, where each criterion is measured according to its own scale (but the same scale for each contestant). Several jury members are involved in the evaluation. Thus we get a problem: how to calculate the aggregated score for whole submission in the above mentioned situation. Another similar problem is making decision on national team selection for other international contests where each candidate is evaluated in terms of several criteria. The chosen methodology for solving this problem is multiple criteria decision analysis (MCDA). The outcome of this paper is the score aggregation method proposed to be applied in LitIO developed using MCDA approaches.
