A Regularized Nikaido-Isoda Function Approach to Multi-Leader-Follower Games
Atsushi Hori, Takayuki Okuno, Ellen H. Fukuda
A multi-leader--follower game (MLFG) is a hierarchical noncooperative game in which leaders compete at the upper level while taking into account the followers' best responses at th…
A closer target setting approach to boundary problems with the Russell graph measure
Atsushi Hori, Kazuyuki Sekitani
A Russell graph measure (RGM) is one of the standard DEA models, but its efficiency measure is not well-defined--or has unacceptable properties--at the boundary of the nonnegative…
Variants of the slacks-based measure with assurance region and zeros in input-output data
Atsushi Hori, Kazuyuki Sekitani
Incorporating an assurance region (AR) into the slacks-based measure (SBM) improves practicality; however, its efficiency measure may not have desirable properties, such as monoton…
A method for multi-leader-multi-follower games by smoothing the followers' response function
Atsushi Hori, Daisuke Tsuyuguchi, Ellen H. Fukuda
The multi-leader--multi-follower game (MLMFG) involves two or more leaders and followers and serves as a generalization of the Stackelberg game and the single-leader--multi-followe…
