Methods for Multiple Objective Decision Making

This means that methods following this approach do not need any interobjective or other subjective preference information from the DM once the problem constraints and objectives have been defined. Thus this approach requires that the DM be able to accept the solution obtained from the method. The advantage of this route is that in the process of obtaining the solution the DM will not be disturbed by the analyst, which is preferable from the point-of-view of the DM. But a major disadvantage then is the necessity for the analyst to make many assumptions about the DM’s preference. This is difficult to do with even the best and most knowledgeable analyst.
