Educational goals

Main aim of this course is the students' familiarization with the way of thiking and the logic of the scientific management by understanding, using and applying the models and the techniques of Operational Research (OR). With the completion of the course students are expected to: • Understand the concept and the logic of OR models • Acquire complete theoretical and practical knowledge of the models and algorithms of the more important OR techniques • Practice in the analysis and tackling of real problems and case studies • Interpret and apply the results of problems' solutions • Solve problems and case studies with the use of specialized software (POM-QM, Win QSB etc) • Understand and pracice in sesitivity analysis of problems' optimal solution

  • to understand the structure and the characteristics of the main mathematical models of OR
  • To acquire complete theoretical and practical knowledge of the models and algorithms of OR techniques and mathematical algorithms
  • To select the appropriate model for the solution of a given problem
  • To apply the appropriate model in both ways; with 'paper and pencil' and the use of specialized software
  • To evaluate and interpret the results of problems' solutions
  • To compare the results of problems' solutions with alternative dat and to come to rational conclusions
General Skills
  • Search, analysis and synthesis of data and information with the use of appropriate technologies
  • Decision making
  • Project design and management
  • Promotion of free, creative and inductive thinking
