An expert system, or knowledge-based, microcomputer program, DXMAS, was designed and developed to diagnose dairy management problems of dairy farmers of Tillamook County, Oregon and, as appropriate, to advance potential farm reorganization and expansion options. The program provokes management action by projecting lost income opportunities attributed to major management problems and missed reorganization and expansion opportunities. The DXMAS program analyzes annual economic and production performance data provided by dairy operators and has demonstrated the ability, in field testing of nine different dairy operations, to emulate dairy management experts in the diagnoses of 95 individual dairy management problems. In those field tests, the DXMAS program identified a variety of management problems and estimated annual lost income opportunities ranging from $25 to $450 per milk cow. Field testing suggested that the DXMAS program can provide a wide range of expert management advice to dairy operators.

Key Words: expert systems • dairy decision support system • management information
