Opis:: The study presented here is related with one of the components of a hybrid decision support system called CAPCAST (Computer Aided Process - CAST), developed under a research project at the Faculty of Metals Engineering and Industrial Computer Science, AGH University of Science and Technology. This is a module for rule generation to serve the knowledge base operating in an expert system. The scope of the system operation involves the selection of technological parameters for the manufacture of machine parts from ductile iron. However, it can be extended to include other materials and technologies.

Tytuł:: A new approach for modelling uncertainty in expert systems knowledge bases
Autorzy:: Niederliński, A.

SWOT knowledge base
Opis:: The current paradigm of modelling uncertainty in expert systems knowledge bases using Certainty Factors (CF) has been critically evaluated. A way to circumvent the awkwardness, non-intuitiveness and constraints encountered while using CF has been proposed. It is based on introducing Data Marks for askable conditions and Data Marks for conclusions of relational models, followed by choosing the best suited way to propagate those Data Marks into Data Marks of rule conclusions. This is done in a way orthogonal to the inference using Aristotelian Logic. Using Data Marks instead of Certainty Factors removes thus the intellectual discomfort caused by rejecting the notion of truth, falsehood and the Aristotelian law of excluded middle, as is done when using the CF methodology. There is also no need for changing the inference system software (expert system shell): the Data Marks approach can be implemented by simply modifying the knowledge base that should accommodate them. The methodology of using Data Marks to model uncertainty in knowledge bases has been illustrated by an example of SWOT analysis of a small electronic company. A short summary of SWOT analysis has been presented. The basic data used for SWOT analysis of the company are discussed. The rmes_EE SWOT knowledge base consisting of a rule base and model base have been presented and explained. The results of forward chaining for this knowledge base have been presented and critically evaluated.

Tytuł:: How to secure a high quality knowledge base in a rule-based system with uncertainty?

Opis:: Although the first rule-based systems were created as early as thirty years ago, this methodology of expert systems designing still proves to be useful. It becomes especially important in medical applications, while treating evidence given in an electronic format. Constructing the knowledge base of a rule-based system and, especially, of a system with uncertainty is a difficult task because of the size of this base as well as its heterogeneous character. The base consists of facts, ordinary rules and meta-rules, which differ from each other regarding both the syntax structure and the semantics. Having no tool to aid designing and maintaining the knowledge base of a rule-based system with uncertainty, we propose the algebra of rules with uncertainty which gives us theoretical foundations to build such a tool. Using the tool, it will be possible to indicate the facts and rules of a redundant character, as well as the pairs of facts and the pairs of rules which are contradictory to each other. The above tool is used in designing and maintaining the knowledge base of a system intended to prognosticate the effects of a medical treatment of the bronchial asthma disease.

Opis:: Celem pracy jest porównanie działania algorytmów wnioskowania dwuwartościowego i rozmytego. Artykuł zawiera opis teoretycznych podstaw działania obu algorytmów, użycia każdego z nich w innej wersji systemu wspomagania decyzji menedżera. Następnie pokazano bazę wiedzy oraz dokładny algorytm wnioskowania, a także przykład użycia w praktyce systemu z wnioskowaniem klasycznym. Ostatnią częścią pracy jest opis analizy podobieństw i różnic pomiędzy algorytmami oraz wynikających z niej wniosków.
The aim of the study is to compare operation of divalent and fuzzy inference. The article contains describing the theoretical basis of operation of both algorithms and illustrated is to use each of them with a different version of the manager’s decision support system. Next is shown knowledge base and accurate inference algorithm and also example of use system of classic inference in practice. The last part of the work is to describe the analysis of the similarities and differences between algorithms and of its conclusions.

Opis:: This article describes functional and diagnostic structure of the equipment of a Wind Power Station. Considering particular operational conditions of a technical object, that is a set of Wind Power Station equipment, this is a significant issue. A structural model of Wind Power Station equipment is developed. Based on that, a functional – diagnostic model of Wind Power Station equipment is elaborated. That model is a basis for determining primary elements of the object structure, as well as for interpreting a set of diagnostic signals and their reference signals.
