INTEGRATING AN EXPERT SYSTEM COMPONENT INTO THE HYDRA IRRIGATION DSS

摘要

HYDRA is a DSS to improve irrigation water use efficiency in Mediterranean agriculture, helping consortia or regional authorities determine water requirements and supporting local irrigation decision making. HYDRA, in addition to soil-water and crop-growth simulation models, database, GIS, and GUI, contains expert systems to control decision scenarios and handle missing or erroneous data. Expert systems coupled to the other components serves as a crisp framework in which to organize intelligent DSS and simulation models for adaptability and portability, alleviating problems arising from sensitivity of the models to assumptions specific to geographic location in which they were developed. HYDRA is portable to multiple platforms (workstation and PC) and operating in many different locations in Europe.
