Description


The subject "Quantitative Methods Applied to Logistics" aims to encourage and develop systemic and scientific thinking, allowing students to raise and develop models and solutions to problems of various kinds. 

More specifically, it aims to provide students with a series of tools and methods that allow them to solve problems in real life, and in the field of logistics in particular.

 

This subject has methodological and digital resources to make possible its continuity in non-contact mode in the case of being necessary for reasons related to the Covid-19. In this way, the achievement of the same knowledge and skills that are specified in this teaching plan will be ensured.

The TecnoCampus will make available to teachers and students the digital tools needed to carry out the course, as well as guides and recommendations that facilitate adaptation to the non-contact mode.

Learning outcomes


  •  Learn to use quantitative tools to model real logistical problems, applicable to the academic and professional field.
  • Learn to optimize these problems by means of exact and heuristic tools, considering the efficiency of the selected method according to the nature of the problem posed.
    • Learn to use a systemic approach to pose and solve problems, identifying key elements, available information, scope and ultimate goal

Working methodology


The teaching methodology of the subject is divided into two parts: face-to-face / online sessions, and independent work.

In the face-to-face sessions the teachers will teach the theory, interspersing practical examples that will facilitate the learning of the knowledge explained and will help the student in the resolution of exercises and practical activities.

In addition, the student will have to work autonomously both to delve into the theoretical and practical concepts seen in class and to do group work.

Learning activities


The activities to be carried out by the student during the course are of various natures in accordance with what is specified in the methodology described.

In this sense and with the aim of covering the proposed goals, face-to-face activities will be carried out as well as in the virtual classroom. In addition, individual and group activities will be carried out.

Evaluation system


The overall grade of the subject takes into account the following aspects:

 

  • Exercises, practices and work (Not recoverable): 20%.
  • Group work (Not recoverable): 30%.
  • Final exam: 50%

 

To pass the course it is necessary to obtain at least a 4 in the final test.

 

recovery In the event that the subject is suspended, only the final test can be recovered. To access the recovery, it is necessary to have appeared in the final test
