# Business Analytics and Decision Optimization Techniques

• Course Code ΨΣ-ΤΔΤΣ-911 Type of Course Mandatory [M]
• Semester 2nd Semester Faculty
• ECTS Credits 7,5

### Objective

The course aims at familiarizing the students with fundamental modeling techniques and analytic methods, for the support of decision making in operational business environments. The covered methodologies constitute invaluable tools in optimizing decision making, in all modern business environments. The expected learning outcome includes the ability of development and analysis of optimization models and the accumulation of experience in implementing and using solving methods. Moreover, it includes the knowledge of decision optimization and forecasting methods, that constitute fundamental analytical tools of decision theory. It is expected that the students will develop the critical ability of choosing the appropriate methodology for each operational decision making problem, and build awareness of each methodology’s advantages and constraints.
