Learning Outcomes

Operational Research is a quantitative course aiming at introducing students to the concept of business research and more specifically into problems related to the management and coordination of business in an organization.  The course begins with the analysis of a real problem as an example and the corresponding data collection of this problem. It continues with the construction of a mathematical model (modeling) that describes the essence of the real problem and ends with solving, drawing conclusions and controlling solutions.

By the end of this course the student will be able to:

1) Knowledge

  • Understand the mathematical theory (concepts, theorems, proofs) related to this cource.
  • Identify the theory-related mathematical formulas and describe how to solve them (e.g M-Method).

2) Skills

  • Distinguish the different cases of mathematical problems and  explain their use in relation to the mathematical problem posed.
  • Evaluate key elements of the theory (e.g. solution through Simplex technique).

3) Capabilities

  • Combine mathematical theory with economic problems that fall within the subject and successfully proceed with their modeling.
  • Rebuild the financial problem (e.g. Maximize a business's profit) and explain the solution found.
  • Be able to evaluate, compare and interpret the economic dimension of the solution in the new context given.
  • Reformat the problem based on its data and proceed to a new solution (e.g. sensitivity analysis).
  • Combine the theoretical framework with the use of a computer program (R, Lindo, Excel) and evaluate its results.

By the end of this course the student will, have developed the following skills:

  1. Ability to exhibit knowledge and understanding of the essential facts, concepts, theories and applications related to the specific course.
  2. Ability to apply this knowledge and understanding to the solution of problems.
