Evaluating the capacity of paired comparison methods to aggregate rankings of separate groups.
Ranking and rating methods have outstanding significance in sports, mainly due to their capacity to predict results. In this paper we turn to their capacity to aggregate separate groups' rankings based on a small piece of information. We investigate under which conditions two or more separate groups can be trustworthily interwoven applying Thurstone motivated methods and an AHP based method. A theorem is proved which guarantees adequate unified ranking based on some links between the groups. We also analyse the robustness of the results.
期刊介绍:
The Central European Journal of Operations Research provides an international readership with high quality papers that cover the theory and practice of OR and the relationship of OR methods to modern quantitative economics and business administration.
The focus is on topics such as:
- finance and banking
- measuring productivity and efficiency in the public sector
- environmental and energy issues
- computational tools for strategic decision support
- production management and logistics
- planning and scheduling
The journal publishes theoretical papers as well as application-oriented contributions and practical case studies. Occasionally, special issues feature a particular area of OR or report on the results of scientific meetings.
