faulty irrigation equipment are referred to the repair centre, to be mended by the repair
centre.

investigate the possibility of carrying out more field repairs with the aid of a portable expert
system, in order to reduce the turnaround time.
The prototyping approach was used, and an evaluation of the final prototype made it clear
that an expert system used in conjunction with 11.1ptop microcomputer would improve the
situation to the extent that only 10% of irrigation equipment would need to be returned to
the repair centre, with majority of repairs being carried out at the customers‘ premises by the
field engineers.
Required
