    The Retail Store and Supermarket Systems are designed to assist in performing the tasks of store operations, in particular, sales, ordering, and ticket-making. They are also designed to solve the problems and perform the tasks of the area headquarters management with the user's programs using data collected from store operation for inventory control, labor scheduling, traffic management, store she...

    Optical scanning components of supermarket systems require machine-readable code. The need for industry-wide cooperation and standardization of a code and symbol was shown. The sources of decoding error in printed optical codes were discussed and a class of codes, the (n, k ) codes, relatively resistant to error, were presented. The UPC code is a (7, 2) code. The UPC code and a method of decoding ... View full abstract»

    The operator's general role in the total Retail Store and Supermarket Systems was discussed briefly and his specific role in the input of data was discussed in some detail. Some of the major differences between the data input requirements of a system for a supermarket and for a retail store included the volume of data and the rate of entry required. These items were discussed in terms of the syste... View full abstract»

    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... View full abstract»

    The ability to make performance projections for the retail system requires a detailed knowledge of the range of retail functions that are executed within the system and a detailed knowledge of the internal design of the system. It is essential that the performance of the system be evaluated over a range of environmental assumptions anticipated in the annual operating cycle of the store. View full abstract»

    Adequate system availability is provided by suitable redundancy of components. The general form of redundancy chosen is a composite form in which the reserve component is operating on its own behalf while ready to take over the tasks of a failed component. In particular, the point-of-sale terminal can pick up the operation of another terminal if failure occurs in midtransaction, and the supermarke... View full abstract»
