Abstract

The development of error control techniques for the mancomputer interface of an automatic checkout system is presented. To minimize human error in man-computer communication in the automatic checkout complex precedence and connection matrix techniques for use with total and partial simulation methods were developed to detect errors in operational automatic checkout computer programs. Precedence and connection matrix techniques for use with total simulation methods were incorporated into a simulation computer program which comprised a total simulation of the computer which controls an operational automatic checkout system. The modified simulation was then used to process several computer runs of an operational automatic checkout computer program. The basic conclusions were that precedence and connection matrix techniques used with total and partial simulation methods can be useful in detecting errors in operational computer-controlled automatic checkout systems.
