PROJECT IPMA: APPLYING DECISION SUPPORT SYSTEM DESIGN PRINCIPLES TO BUILDING EXPERT‐BASED SYSTEMS*
探讨了用决策支持系统设计技术构建专家系统的方法，并以俄勒冈州立大学昆虫学系实际使用的IPMA系统为例，该系统帮助推广人员为果园主提供梨树害虫治理建议。
ABSTRACT There currently is no widely accepted design framework for building expert systems. Knowledge engineers describe the process in terms of a set of heuristics or as a series of phases. Most paradigms are based on post‐development reflections. This paper explores an expert‐based system constructed using decision support system design techniques. An actual system in experimental use at the Department of Entomology, Oregon State University, was designed using the approach presented. The system, Integrated Pest Management Assistant (IPMA), will be used by extension agents to help orchard owners make decisions regarding pear tree pest infestations and to offer remedial strategies for eradicating potentially destructive insects.
