A new way using utility functions for multi-choice goal programming models

This study proposes an idea of another way of using utility functions with multi-choice goal programming (MCGP) models. By examining the way the previous study is using utility function with MCGP, some drawbacks of such a way are examined. These drawbacks can mistakenly result in an incomplete representativeness of the original MCGP with utility functions model and thus lead to the inability of the model to appropriately assess and express the real preference structure of a decision maker. This study corrects the way utility functions are used with MCGP. Such a new way is validated by using it to express a decision maker preference structure pertaining to a goal, which underlies his/her real oral statements during decision making.
