【Abstract】 In this paper, based on the basic throry of I O analysis and in accordance with concrete characteristics, we construct a super I/O model by combining I/O model with the optimal model. After a superior model has been presented, with the help of linear theory, we can analyse the existence of solution of the model.更多还原
