A pioneer in commercializing expert system technology, Teknowledge released two so-called "expert system shells" in mid-1984. It soon became apparent that product customers were using these tools in ways that differed from what the developers envisioned. Even internal to Teknowledge, there was considerably controversy over the value of these tools. The debate centered on the tradeoffs between t...

expert system to aid the M1 Abrams tank mechanic find-and-fix problems in the AGT-1500 turbine engine. TED was designed to provide the apprentice mechanic with the ability to diagnose and repair the turbine engine like an expert mechanic. The expert system was designed and built by the U.S. Army Research Laboratory and the U.S. Army Ordnance Center and School. This article discusses the relevan...

This paper deals with the proposal of structure of an expert system for SPC which enables to user to select right control chart identify more quickly root cause of assignable variation and to accept suitable effective action in time.

In this paper we present a functional representation of human expert reasoning throughout its statements when assessing the condition of a given object. The human expert statements are represented as conjunctions of elementary propositions. We demonstrate that the conjunctions of elementary propositions can be represented as qualitative additions of qualitative functions in the Q-algebra (Q, ≈,...

In this study, an expert system was developed for a quadricycle four bar mechanism with control of transmission angle. Different types of available synthesis methods are studied and the suitable synthesis procedure is selected for developing the expert system.

This issue of the Journal is devoted to being a little more explicit about the miracle that occurs in expert systems. In this issue, Dr. DeTore offers an eloquent explanation of expert system fundamentals. Dr. Burr argues that expert systems can be useful in several kinds of projects; the objectives must be clear before the expert system is designed. Paul Howman shares MONY’s experience in deve...

ultrasonic machining (usm) is a mechanical material removal process used to erode holes and cavities in hard or brittle work pieces by using shaped tools, high-frequency and an abrasive slurry. this paper addresses the concept and development of an expert system (es) for hard and brittle material, such as glass, quartz, diamond, carbides, semi conducting materials, ceramic and graphite which ca...

pemphigus is a rare autoimmune blistering disease with different phenotypes. the evaluation of therapeutic interventions requires a reliable, valid and feasible to use measurement. however, there is no gold standard to measure the disease activity in clinical trials. in this study we aimed to introduce the pemphigus vulgaris activity score (pvas) measurement and to assess the convergent validit...
