This book was released on 1987 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of expert systems as decision aids in decisionmaking organizations will modify their performance. First, a model of symbolic computation with fuzzy logic, using Predicate Transition Nets, is presented. The basic operators AND, OR, and NOT are then used to model the most common kind of expert systems: the consultant expert system in which production rules are used for knowledge representation. This model allows to simulate the dynamical behavior of the expert system in its search for a solution and to evaluate its response time for a given input. This response time depends on the number of rules scanned by the system and on the number of interactions with the user. An Air Defense Command and Control application, involving a hierarchical organization, where the expert system is used as an aid in the fusion of inconsistent information, is then developed. A strategy involving the use of the expert system is compared to two other strategies expected to be used by a decision making facing this problem. Measures of performance (workload, timeliness, and accuracy) are evaluated for each of these strategies. The results show that the use of the expert system improves significantly the accuracy of the organization, but requires more time and increases the workload of the decision making using it.

Available in PDF, EPUB and Kindle. Book excerpt: A class of decision aids that is receiving attention in the development community is based on artificial intelligence and especially expert systems. This paper presents a procedure for assessing to what extent the measures of performance of an organization are modified when an expert system is introduced. First, a model of symbolic computation with fuzzy logic, using Predicate Transition Nets, is presented to model the most common kind of expert systems the consultant expert systems. This model allows to evaluate its response time for a given input. An Air Defense problem in which command and control involves a hierarchical two decisionmaker organization, where the expert system is used as an aid in the fusion of inconsistent information, is then presented. A strategy involving the use of the expert system is compared to two other strategies expected to be used by a decisionmaker facing this problem. Measures of performance (workload, timeliness and accuracy) are evaluated for each of these strategies. The results show that the strategy involving the use of the expert system improves significantly the accuracy of the organization, but requires more time and increases the workload of the decisionmaker using it.

Download or read book Fuzzy Sets Decision Making and Expert Systems written by Hans-Jürgen Zimmermann and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the two decades since its inception by L. Zadeh, the theory of fuzzy sets has matured into a wide-ranging collection of concepts, models, and tech niques for dealing with complex phenomena which do not lend themselves to analysis by classical methods based on probability theory and bivalent logic. Nevertheless, a question which is frequently raised by the skeptics is: Are there, in fact, any significant problem areas in which the use of the theory of fuzzy sets leads to results which could not be obtained by classical methods? The approximately 5000 publications in this area, which are scattered over many areas such as artificial intelligence, computer science, control engineering, decision making, logic, operations research, pattern recognition, robotics and others, provide an affirmative answer to this question. In spite of the large number of publications, good and comprehensive textbooks which could facilitate the access of newcomers to this area and support teaching were missing until recently. To help to close this gap and to provide a textbook for courses in fuzzy set theory which can also be used as an introduction to this field, the first volume ofthis book was published in 1985 [Zimmermann 1985 b]. This volume tried to cover fuzzy set theory and its applications as extensively as possible. Applications could, therefore, only be described to a limited extent and not very detailed.

Download or read book Expertise and Decision Support written by F. Bolger and published by Springer Science & Business Media. This book was released on 2007-08-19 with total page 279 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together a range of contributors from Europe and North America. All contributions were especially commissioned with a view to e- cidating a major multidisciplinary topic that is of concern to both academics and practitioners. The focus of the book is on expert judgment and its interaction with decision support systems. In the first part, the nature of expertise is discussed and characteristics of expert judges are described. Issues concemed with the eval- tion of judgment in the psychological laboratory are assessed and contrasted with studies of expert judgment in ecologically valid contexts. In addition, issues concerned with eliciting and validating expert knowledge are discussed. Dem- strations of good judgmental performance are linked to situational factors such as feedback cycles, and measurement of coherence and reliability in expert ju- ment is introduced as a baseline determinant of good judgmental performance. Issues concerned with the representation of elicited expert knowledge in kno- edge-based systems are evaluated and methods are described that have been shown to produce improvements in judgmental performance. Behavioral and mathematical ways of combining judgments from multiple experts are compared and contrasted. Finally, the issues developed in the preceding contributions are focused on current controversies in decision support. Expert judgment is utilized as a major input into decision analysis, forecasting with statistical models, and expert s- tems.
