Course detail

Statistics and Optimization

FSI-USO-AAcad. year: 2021/2022

The course makes students familiar with introduction to operations research techniques for engineering problems. In the first part basic of probability theory and main principles of mathematical statistics (descriptive statistics, parameters estimation, tests of hypotheses, and linear regression analysis] are presented. The second part of the course deals with fundamental optimization models and methods for solving of technical problems. The principal ideas of mathematical programming are discussed: problem analysis, model building, solution search, especially and the interpretation of results. The particular results on linear and nonlinear programming are under focus.

Learning outcomes of the course unit

Students obtain the needed knowledge of the probability theory, descriptive statistics and mathematical statistics, which will enable them to understand and apply stochastic models of technical phenomena based upon these methods. Students will learn fundamental optimization topics (especially linear and non-linear programming). They will also become familiar with useful algorithms and interesting applications.

Prerequisites

Fundamental knowledge of principal concepts of Calculus and Linear Algebra in the scope of the mechanical engineering curriculum is assumed.

Co-requisites

Not applicable.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Course-unit credit requirements: active participation in seminars, mastering the subject.The exam result is awarded based on the result in a written exam involving modelling-related, computational-based, and theoretical questions. The short oral exam is also included.

Aims

The course objective is to make students familiar with basic concepts, methods and techniques of probability theory and mathematical statistics as well as with the development of stochastic way of thinking for modelling a real phenomenon and processes in engineering branches. The course objective is to also emphasize optimization modelling together with solution methods. It involves problem analysis, model building, model description and transformation, and the choice of the algorithm. Introduced methods are based on the theory and illustrated by geometrical point of view or real-world data experience.

Specification of controlled education, way of implementation and compensation for absences

The attendance at seminars is required as well as active participation. Passive or missing students are required to work out additional assignments.
