$\overline{y}_{f}^{\textrm{\textrm{C,Syn}}}$ | upper bound of capacity is defined,then we impose constraints on maximum CO2 input capacity of synthetic fuels resource |
$\underline{y}_{f}^{\textrm{\textrm{C,Syn}}}$ | lower bound of capacity is defined,then we impose constraints on minimum CO2 input capacity of synthetic fuels resource |
