Abstract
This paper describes a prototype of a farm level expert (FLEX) system providing firm-level decision support for cotton farms in central Texas. The system was developed on a Pyramid 90x computer running the UNIX operating system. The system integrates a farm and field database with simulation models and expert system to provide advice on key strategic and tactical decisions relating to cotton production throughout the calendar year. CLIPS, the C-Language Integrated Production System developed by NASA, was used as the inference engine. Modifications were made to CLIPS to provide a menu-driven user interface and frame-like knowledge representation through dynamic access to C-language structures in the database. A rudimentary model-based reasoning component was added and is being expanded to allow the system to deal with some unforeseen field situations. Currently, the program is being ported to an IBM PC/AT for delivery to the field. Components of the system are being tested in the field.
