Expert systems
Veselovský, Michal ; Konečný, Pavel (referee) ; Dvořák, Jiří (advisor)
Expert systems (ES) are commercially one of the most succesfull use of artificial intelligence (AI) - since eighties of the 20th century. They are often used in medicine, industry, science, trade, banking etc. Expert system is a software using knowledge of human experts for solving very complicated tasks and problems, which would otherwise require participating or consultation of one or more specialists on these issues. This software simulates decision-making of human expert in solving complicated tasks, and tries to reach the most probable result, ideally same as the expert´s opinion. Typical feature of expert systems, differencing it from usual software, is separating of decision making engine (inference engine) and knowledge base – same expert system with different knowledge base may serve for different purposes. This feature is used for creating empty expert systems – shells. Other features, which may not occur at all ES, are ability to make decision with uncertainty, and ability to explain the decision. Goal of this work is to describe basic principles of ES, using freely available information sources, and then describe and analyze resources for creating of these systems, using mainly information from official web sites.

The content of the internal knowledge base was created to correspond with the results of my diploma thesis. The contribution of this dissertation is the identification and assessment of the most fre-quent problems of agile projects of an existing company, identification of possible impacts and recommendation of possible solutions. The other contribution is the identification of the project categories which are linked to the identified problems. Last but not least, the main benefit of this thesis is the creation of a new internal project management knowledge base which will help to share the experience among all the projects and in this way it will help to prevent the spread of these problems. This diploma thesis is divided into two main parts, theoretical and practical. In the theoretical part, there is a definition of "agile methodologies", a description of their typical examples and statistics as well as modern trends in the area of the development of agile projects. The practical part is divided into four chapters. They contain the results of the company's SWOT analysis and the results of the internal agile development survey. Then there is a presentation of the identified agile development problems, their possible impact and the recommendation how to deal with them. There is a full description of all the identified categories of projects and their identified problems with their assessment criteria as well as time-proven ways how to effectively deal with them. The last chapter contains and internal project management knowledge base which has been done by myself. The knowledge base may be very useful in the project management now and in the future.
