In the equations, only common mathematical operations, included e.g. in practically all spreadsheet programs, are used: addition, subtraction, multiplication, division, power and logarithm. Categories or regions with sharp boundaries are often used to characterize the effects...

... evolution and by huge amount of information: for instance, new materials are continuously developed and made available to the market and the understanding of corrosion mechanisms improves continuously. In this context, expert systems are intended as design tools suitable to make available to several users...

...The Role of Modelling The possibility of embedding various calculation procedures into the expert systems emphasizes the role of mathematical modelling of empirical relations. The mathematical expressions in such models need not have a physical or chemical background: if they give correct results...

... payoff will be achieved for the ES. Abstract Failure analysis is a complex task, requiring considerable knowledge and skill, some of which might be outside the experience of the engineer concerned. To help the engineer, a case-based reasoning tool (Failure Analysis Diagnostic Expert System) is being...
