Educational Goals

Network Theory is a relatively new area of ​​Science within Operations Research and Graph Theory. Recent proposals in the literature consider that it is now a new paradigm. This course provides an introduction to the classic concepts of graph theory and network optimization. Next, newer concepts related to Social Network Analysis are introduced in terms of their structure. Particular emphasis is placed on the modeling of problems related to the general subject of Economics and Management, such as in the analysis of networks of employees – customers – companies, credit institutions, stocks, but also in the production of new information through data mining techniques.

After successful completion of this course, students will be able to:

  • Define the concepts graph, network and their components.
  • Know and apply classical optimization algorithms in networks.
  • Model classic business research problems in network form and will solve them (shortest – longest paths, PERT, CPM).
  • Realize the utility of representing interconnected units in various fields of the contemporary economic and social situation.
  • Know concepts related to the importance of specific nodes.
  • Analyze networks in terms of node importance using specific software.
  • Recognize the need for grouping and the various structures (cliques, cores, clans, communities) and gain knowledge and experience in how to search for them
  • Implement one or more social networks in the context of individual or group work and will study them macroscopically as well as at the node level.
  • Learn about link analysis.
  • Evaluate and classify specific networks into categories (small worlds, scale free, random).
  • Develop abilities to acquire new knowledge related to network theory and its manifestations in their science.
