I.C.4. Product category relations in the grocery retailing industry

Consumers, during a single shopping trip, often purchase a basket including various product categories. Some purchase category relations may be identified and differ regarding their types and nature. Retailers may integrate these relations in their store management in different ways: by exploiting new cross-category actions, by allocating more efficiently their resources or by developing their strategic positioning on their shoppers habits (see also projects I.C.3 and III.B.3).
