Decision Theory

This course (8th semester, 5 ECTS) examines the theoretical and applied background of decision-making under conditions of certainty, risk, and uncertainty. It introduces students to basic concepts, techniques, and models for optimizing decisions in complex administrative and operational environments. It covers decision trees, game theory (strategies, Nash equilibria), linear programming, queuing theory, utility functions, multi-criteria decision analysis (MCDM), and decision support systems (DSS). Diagrammatic methods like GANTT, CPM, and PERT, as well as operational scenarios, are also analyzed. Assessment is via a written final exam (100%). The course is taught in Greek, with availability in English for Erasmus students.
