Objectives

This course aims to give to Engineering students a set of concepts, principles, technics and appropriate methods to approach and solve representative problems of real-world situations within the Engineering Economics, such as the designing, planning and implementation of projects. 

Essentially based on a practical approach, this course emphazises the benefits of concepts such as the time value of the money, the equivalence of interest rates, the cost/benefit analysis and the break-even analysis. Such concepts give to the student the knowledge to make investment decisions in a context of certainty, risk and uncertainty, supporting the choice of the best investment alternative.

Teaching method

In order to facilitate the development of competencies, this course use different pedagogical approaches. 

- Lectures;

- Exercices from Sebenta;

- Exercices/exams from previous years;

- Case studies; 

- Discussion of group projects.

Evaluation method

Discipline success can be obtained in continuous assessment  or in a final exam.

In continuous assessment the success on the discipline will be evaluated by three tests, and an assignment. It is mandatory for obtaining the frequency approval of the course that the student delivers and obtains the approval on the assignment according to the requirements.

The assessment is, 70% individual and 30% group project. Final grade is the weighted average of those assessments. Approval for the UC is subject to obtaining a final mark of not less than 9.5, while the average of two tests should be  equal or more than 9,5. 

The frequency to the UC is assigned by the active participation in group work.

The final mark evaluation is obtained applying the following formula: 

(grade of 1st test*0,30) + (grade of 2nd test*0,40) + (grade of the assignement*0,30). 

The final mark will be rounding to two decimal (i.e. 12,50 = 13)
