| summary | There are numerous examples of situations where a group of agents need to find a collective interval based on their individual preferences: think for instance of a committee having to agree on a time slot for a meeting, that is asked to express their preferences over a starting/ending time (or on a starting time and a duration). In this talk I will present ongoing work about the impact that the choice of representation for the intervals has on their aggregation.
Specifically, I will show that on discrete scales we cannot have natural rules that can be defined both as rules that aggregate separately the left and right endpoints of intervals and as rules that aggregate separately the left endpoints and the interval widths; however, on continuous scales such rules correspond to the weighted averages of the endpoints of the individual intervals. |
