Over recent years there has been a major increase in commercial awareness of the subject of store location analysis. A variety of articles have appeared in the press and a number of conferences and seminars have been organised to consider the topic. Davies and Rogers' recent publication (1984), however, provides the most comprehensive single source currently available to the store location analyst. Alternatively, the extensive literature on consumer behaviour research provides many helpful guidelines (e.g. Shepherd and Thomas, 1980).
