  • 2206 Design of Frame Structures with Negative Poisson's Ratio by Using Mixed Integer Programming  [in Japanese]

    KURETA Rui , KANNO Yoshihiro

    … Based upon the conventional ground structure method, the optimization problem is formulated as a mixed integer linear programming (MILP) problem that maximizes the output displacement when the displacement of the input node is prescribed. … The MILP problem is solved globally by using, e.g., a branch-and-cut method. …

  • A branch and cut based method for energy system optimization problems

    Saeki Osamu , Yamada Satoshi , Tsuji Kiichiro

    エネルギーシステムにおける最適化問題には機器の起動・停止や設備の設置・非設置を検討する問題も多く存在する。起動・停止や設置・非設置は離散変数として定義されるため、一般的に多大な時間を必要とする混合整数計画問題となる。このような問題の解法には分枝限定法や切除平面法があるが、分枝限定法に切除平面法を組み込んだ分枝カット法が近年見直されている。本研究では、分枝カット法に内点法を適用した手法を示し、問題例 …
