Changes in the course due to coronavirus

Autumn 2020 the exams of most courses at the MN Faculty will be conducted as digital home exams or oral exams, using the normal grading scale. The semester page for your course will be updated with any changes in the form of examination.

See general guidelines for examination at the MN Faculty autumn 2020.

Course content

STK4405 provides the foundation of probability theory needed to compute the reliability of a system, i.e., the probability that a system is functioning, when the reliabilities of the components which the system is composed of are known. Examples of systems are energy systems and networks. The course will also cover various examples of use of risk analysis for industrial applications. The material is illustrated by different simulation techniques. STK4405 is an introduction to more advanced studies, but is also suitable as a support course to studies in other fields and as further education for realists and engineers.

Learning outcome

After completing the course you:

  • know what coherent systems are, and can represent such systems by paths and cuts
  • can compute the reliability for systems of components
  • know what discrete event simulation is, and can apply different simulation techniques to do computations related to risk- and reliability analysis
  • can compute the reliability importance of components
  • can perform a risk- and reliability analysis in various practical situations.

Admission to the course

Students admitted at UiO must apply for courses in Studentweb. Students enrolled in other Master's Degree Programmes can, on application, be admitted to the course if this is cleared by their own study programme.

Nordic citizens and applicants residing in the Nordic countries may apply to take this course as a single course student.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures for international applicants.

Overlapping courses
