Outline of Annual Research Achievements

本年度は申請書に記載した基礎研究2の動的な多目的分散制約最適化問題の定式化及び,アルゴリズムの開発に着手した.具体的には,マルチエージェントシステムにおける重要課題の1つであるチーム編成問題にロバスト性を考慮したロバストなチーム編成問題を多目的制約最適化問題として定式化し,この問題を解くアルゴリズムを開発した.チーム編成問題とは,異なるスキルをもつエージェントの集合から,与えられたタスク集合を達成するような部分集合(チーム)を決定する問題である.ロバストなチーム編成問題において,あるチームがk-ロバストであるとは,チーム内から任意のk人を取り除いたとしても,残りのチームメンバーで,与えられたタスク集合が達成可能である事を意味する.さらに,この問題を動的環境へと拡張した動的チーム編成問題の定式化及び,この問題を解くアルゴリズムの開発も行った.本研究成果は,マルチエージェントシステムに関する最難関国際会議 the 14th International Conference on Autonomous Agents and Multiagent Systems (AAMAS-2015)及び,人工知能分野における最も権威のある国際会議 the 25th International Joint Conference on Artificial Intelligence (IJCAI-2016)に論文が採録された.その他にも,複数のパレート最適解の中から代表的な解を求解するフレームワークの定式化及び,その求解方法を提案した.本研究は知識表現分野の最難関国際会議 the 15th International Conference on Principles of Knowledge Representation and Reasoning (KR-2016)に論文が採録された.

Current Status of Research Progress
Current Status of Research Progress

1: Research has progressed more than it was originally planned.

Reason

* 初年度及び本年度の研究計画である基礎研究は概ね達成しており,研究成果も挙げている.
* 主に来年度のテーマとしていた応用問題である時間割作成やナース・スケジューリング問題にも着手できた.
* 協同研究者らと頻繁に打ち合わせ・議論・成果発表を行う機会をもてたことが成果につながった。

Strategy for Future Research Activity

当初の計画どおり,応用問題を重点的に進める.時間割作成問題に関しては,すでにいくつかの研究成果が出ており,現在,timetabling分野の国際会議 11th International Conference on the Practice and Theory of Automated Timetabling (PATAT 2015) に論文を投稿している.ナース・スケジューリング問題に関しては,いくつかの研究成果が出ており,International Joint Agent Workshop and Symposium (IJAWS 2015)に論文が採録されている.現在は,神戸大学付属病院と連携し,実データを基にしたナース・スケジューリング問題の研究に着手している.
