However, the non-uniqueness of optimal weights problem has reduced the effectiveness of this method. To address this problem, scholars proposed to use secondary goals and presented many secondary goal models. In this pa-per, two new secondary goal models are presented, in order to further extend the above-mentioned existing secondary goal models....... %U https://scientiairanica.sharif.edu/article_21994_664cd73b3c50917d4aa7281a2e12764a.pdf
