The aim of the course is that the students gain the capability
of utilizing methods and tools for risk analysis and evaluation as
a basis for making decisions concerning risk management within the
safety area. Furthermore, the course is aimed at providing a
foundation for continuing studies in the risk management field.
Knowledge and understanding
For a passing grade the student must
- be able to describe common accident models within the area of
safety and be able to present the assumptions on which they are
- be able to decribe the basic principles for risk assessment
within the safety area and process safety.
- be able to descrbe both qualitative and quantitative methods
for riskanalysis of systems related to safety.
- have basic knowledge about methods that are based on barrier
perspective and adapted to complex systems.
- have basic knowledge about research and development within risk
analysis and evaluation in the safety area.
Competences and skills
For a passing grade the student must
- be able to identify risks in systems related to safety.
- be able to analyse such systems and calculate relevant risk
- be able use qualitative and quantiative methods and tools for
risk assessment, also in situations that are new for the
- be able to evaluate the contents of existing risk
- be able to, both orally and in writing, present the results and
discuss the implications of an risk assessment in a way
understandable to persons with different knowledge
- be able to utilise material in scientific publications that is
relevant for risk analysis within the area of safety.
- demonstrate the capacity to plan and undertake project
assignments and in doing so focused on risk assessments demonstrate
a capacity for teamwork.
Judgement and approach
For a passing grade the student must
- be able to assess the applicability of various risk analysis
methods depending on the nature of the problem and within the
framework of safety.
- be able to carry out analyses in a way that takes into
consideration both scientific, societal and ethical aspects.
- be able to realise and judge the limitations of a conducted
The course covers an overview of risk assessment in safety,
accident theories, barrier perspectives, complex systems and
quality of risk assessments. And in-depth consideration and
applications of qualitative and quantitative methods for risk
analysis, likelihood estimations, consequence analysis, uncertainty
analysis, risk presentation, risk evaluation and the risk
Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: The examination represents a combination of results individual assignments, group assignments and a written examination. The examination consists of both questions on theory and questions of a problem-solving nature. Participation in obligatory seminars is required.
The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
Code: 0117. Name: Written Examination.
Credits: 4. Grading scale: TH. Assessment: Written examination. Contents: This element constitutes the whole course including an overview of risk assessment in safety, accident theories, barrier perspectives, complex systems, and quality of risk assessments. And in-depth consideration and applications of qualitative and quantitative methods for risk analysis, likelihood estimations, consequence analysis, uncertainty analysis, risk presentation, risk evaluation and the risk assessment process.
Code: 0217. Name: Indivudal Assignments and Group Assignments.
Credits: 3,5. Grading scale: UG. Assessment: Successfully completed individual assignments and project assignments completed in groups. Contents: During the course a number of individual assignments as well as a major group project assignments are to be completed. For the project assignments, supervisors are available for consultation.
Assumed prior knowledge: FMA430 Calculus in Several Variables or FMAB30 Calculus in Several Variables
Basic course in risk assessment, at least 7,5 hp.
The number of participants is limited to: No
Completed university credits within the program. Within programs where the course is given as a compulsory course students are guaranteed admission.
Thereafter priority is given to students enrolled in programs that include the course in the curriculum.
