Expert Systems

Course Description

Project oriented course. Fundamentals of automated reasoning and deductive systems. Application of automated reasoning in mathematics, digital systems design (verification of hardware and software) and problem solving. Rule-based expert systems augmented with rule weighting, certainty factors, and fuzzy logic. Applications in technical systems synthesis, diagnostics, and process control. Probabilistic reasoning based on Bayesian belief networks. Applications of Bayesian networks in diagnostics and prediction. Project work involves hands-on experience with prevalent expert system shells (e.g. Otter, CLIPS, FuzzyCLIPS, HuginLite).

General Competencies

The course gives students knowledge and skills for solving medium to hard problems from diverse expert systems application domains.

Learning Outcomes

  1. define and describe expert system and its main constituents.
  2. distinguish class of problems suitable for solving with expert systems.
  3. breakdown the problem and select crucial parts.
  4. assemble various parts of knowledge and skills in order to devise the approach to solution.
  5. design and create expert system suitable for solving particular problem.
  6. appraise the quality of solution and justify the employed techniques.

Forms of Teaching


The course is organized in two cycles. The first cycle consists of 7 weeks of lectures and a week of midterm exam. The second cycle consists of 3 weeks of lectures and 3 weeks of students' projects presentations and discussions.


Grading is based on midterm exam and the success of implemented project.

Other Forms of Group and Self Study

Students must conceptualize, design and realize expert system either individually or in pairs.
