Store performance studies for the Supermarket System

The functional objective of the Supermarket System is to provide complete shopper checkout and store support facilities and to capture vital operational data at the point-of-sale. The system consists of a store controller and point-of-sale terminals that communicate with the controller through two store loops (maximum of 12 terminals per loop). The controller is capable of batch communication with a System/370 host computer on a switched line. The controller can also provide back-up foar companion (remote) store whose controller has failed. Communication with the terminals in the remote store is through the store loops in the remote store and a switched line (for a detailed description of the system, see the paper by McEnroe, Huth, Moore, and Morris; and of the scanner, see Dickson and Soderstrom).
