  • Understands and applies the mathematical and scientific principles and procedures of vehicle simulation and optimization.
  • Understands and can apply in a wide circle the theories and terminologies elaborated for professional area of vehicle simulation and optimization.
  • Knows and understands the basic facts, limits and development possibilities of the vehicle simulation and optimization.
  • In details knows and understands the modeling methods of the vehicle simulation and optimization.
B. Skills
  • Able to apply in innovative way the required mathematical and scientific principles and procedures for solving the problems connected with the vehicle simulation and optimization.
  • Able to apply, to analyze and to evaluate the methods applied in the field of the vehicle simulation and optimization.
  • Shows ability to apply integrated knowledges in the field of the vehicle simulation and optimization.
C. Attitudes
  • Open and receptive to know and to accept the developments and innovations which are taken place on the field of the vehicle simulation and optimization. The sense of vocation is depth.
  • Accepts the professional and ethical values-system connected with the professional area of the vehicle engineering.
  • Pursuing to use complex and on system-oriented mentality based approach to the processes.
D. Autonomy and Responsibility
  • Pro-activity in professional work, the self-standing selection and application of the solution methods.
  • Making decision circumspectly and responsibility.
18. Requirements, way to determine a grade (obtain a signature)

The criterion of signature is both the active participation at the class (attitude), and during the semester successfully written two midterm tests (knowledge, ability, autonomy). In the fields of attitudes and autonomy the results achieved in the semesters are included in the final classification by weight 50%. At the end of semester there is an examination (knowledge, ability, attitude).

19. Opportunity for repeat/retake and delayed completion
Possibility to refit the midterm exams, to repeat the examination, properly to the Study and Exam Regulations.
