In this presentation, we consider a facility location game on a one-dimensional line segment, i.e., a problem in which participating agents declare their positions on a one-dimensional line segment and a mechanism determines the placement of facilities based on these declarations. In particular, we focus on the ordered weighted average (OWA) mechanisms and discuss its non-obvious manipulability. An OWA mechanism is a mechanism that orders the agent's reported values in ascending order, applies weights according to that order, and returns the sum of the weights. In this presentation, we analyze how the non-obvious manipulability changes by changing the weights in an OWA.
