PLANT STATE DIAGNOSTIC DEVICE, AND METHOD AND PROGRAM FOR DIAGNOSING PLANT CHEMICAL MANAGEMENT STATE

摘要

PROBLEM TO BE SOLVED: To provide an abnormality diagnostic device which makes it possible to easily put event diagnostic knowledge that plant chemical management experienced individuals have together in a knowledge base in the absence of a computer engineer which knows a diagnostic system much, enables even a plant chemical management engineer who does not have much experience to easily use it, and can easily put newly experienced event diagnostic knowledge in the knowledge base. SOLUTION: The device is equipped with a means for generating and editing a diagnostic knowledge base of plant chemical management states by generating a causality tree diagram from a characteristic factor diagram used to investigate and handle the cause of event occurrence, a means for generating and editing a reference value database, a means for generating and editing a plant data evaluation result database, a means for diagnosing plant chemical management states, and a means for storing and editing diagnosis results.
