Linear Algebra, Calculus, Fundamentals of Operational Research

Theoretical and methodological concepts are presented in tutorial lectures, being motivated by real-world problems and illustrated with application examples.

Software (commercial and public domain) packages are used to obtain solutions to the mathematical models, thus freeing the students for the more creative tasks of problem formulation, model building and critical analysis of results.

Assignments will be offered, involving the development of mathematical models for a real-world problem and the generation of the optimal solutions.

Providing the students with methodological and application competences in the context of optimization in engineering problems, enlarging the range of problems addressed in Fundamentals of Operational Research, in particular by considering integer variables and multiple objective functions in optimization problems. In addition, meta-heuristic approaches are introduced to deal with complex optimization problems of combinatorial nature.

1. Integer programming (I). Applications of IP. IP models. Use of binary variables in mathematical programming models. Methods to solve IP problems. The "branch-and-bound" algorithm. IP with binary variables. The Balas’ algorithm. The 0-1 knapsack problem. Problem reformulation. Stability of the optimal solution in IP models.

2. Multi-objective linear programming. Revisiting the goal programming model. Concepts of non-dominated solutions. Scalarization processes. Interactive methods. The STEM method. Multiobjective programming with integer variables.

3. Meta-heuristics in optimization problems. Tabu search. Simulated annealing. Genetic algorithms. Main steps of a genetic algorithm. Genetic operators. Particle swarm optimization. Differential evolution.
