A structured framework for efficient problem solving in diagnostic expert systems

Analytical and knowledge‐based redundancy for fault diagnosis in process plants

“…Thus, to provide a necessary general structure for the knowledge base, a malfunction hierarchy is identified for organizing knowledge about the system Ramesh et al, 1988). The use of malfunction hypothesis as the conceptual basis for constructing the hierarchy provides an efficient problem-solving framework, allows for a natural decomposition of the domain for focus and control, and supports organized and efficient knowledge-acquisition.…”

Managing qualitative simulation in knowledge‐based chemical diagnosis

“…This technology, as a basis for diagnostic methods in the chemical process domain, has been investigated considerably (Chester et al, 1984;Davis et al, 1985;Kramer, 1987, 1989;Shum et al, 1988Shum et al, , 1989Venkatasubramanian and Rich, 1988;Ramesh et al, 1988;Oyeleye et al, 1989;Calandranis et al, 1990;Petti et al, 1990).…”

“…Successful systems using task-specific architectures have been constructed in the chemical process, discrete manufacturing operations, and electronic domains for the diagnosis of single and independent multiple malfunctions (Shum et al, , 1989Ramesh et al, 1988Ramesh et al, , 1989Myers et al, , 1990McDowell et al, 1990).…”

“…Included among these efforts in the chemical process domain and playing an important role in the construction of diagnostic knowledge-based systems, are problem-solving approaches based on a task-specific architecture Ramesh et al, 1988;Shum et al, 1989). Rather than a feature of the chemical process domain, task-specific architectures are a theoretical viewpoint for constructing knowledge-based systems.…”

A New Engine Fault Diagnosis Method Based on Multi-Sensor Data Fusion

“…At present, there are many methods for fault diagnosis. For example, the methods based on expert systems [5][6][7], which utilize the experience accumulated by domain experts in long-term practice. In these kinds of methods, a computer program is designed to simulate the reasoning and decision-making process of human experts to diagnose faults.…”
