The deviation method of minimum subordinative degree with ‘favouritism’ information for the index attribute

First, we introduce a new concept – the deviation method of minimum subordinative degree which is used in some multi-objective decision making. Then, we apply this method to the multiple attribute decision problem that has ‘favouritism’ information for the index. Thus, we get a simple, practical method for such decision making. A practical example is also given to show the effectiveness of this method.
