Abstract: Picking a restaurant for a group of people to go for lunch can be hard work. We developed a restaurant selection method based largely on pair-wise comparison of our group members' preferences for a set of criteria and sub-criteria. Largely, but not entirely. The first phase involves picking the kind of food the restaurant should serve. It would, of course, have been possible to do pair-wise comparisons on different types of cuisine. However, in an effort to make the process more like our own real life experience, we substituted a consensus model with veto right for each group member. Let's suppose somebody suggests, "let's have Chinese food for lunch." If this is agreeable to everyone, the appropriate choice can then be made from the list of five Chinese restaurants. If someone should say, for example, "I just had Chinese food last night at home for dinner, can't we do something else?" Chinese would be rejected and another kind of food would be proposed. If every kind of food available is vetoed by at least one member, the group goes hungry! We believe that this more closely resembles the way such groups actually decide. Once the initial choice is made, the particular restaurant is chosen in a straightforward HDM fashion.
