山内さん ご回答いただき、誠にありがとうございます。 ご教示いただきましたUtilizationを調査、検証してみます。 ＞＃colocationの-inf制約を利用することで、うまく行きそうな気もしますが・・たぶん、うまく行かないと思います。 こちらで以下の2パターンを検証しましたが、どちらともうまく行きませんでした。。。 パターン1 (組み合わせ) colocation -inf: groupA groupB colocation -inf: groupA groupC colocation -inf: groupA groupD colocation -inf: groupA groupE colocation -inf: groupB groupC colocation -inf: groupB groupD colocation -inf: groupB groupE colocation -inf: groupC groupD colocation -inf: groupC groupE colocation -inf: groupD groupE パターン2（順列） colocation -inf: groupA groupB colocation -inf: groupA groupC colocation -inf: groupA groupD colocation -inf: groupA groupE colocation -inf: groupB groupA colocation -inf: groupB groupC colocation -inf: groupB groupD colocation -inf: groupB groupE colocation -inf: groupC groupA colocation
