ÚSI-RTSRPAcad. year: 2020/2021
The subject “Statistical Process Control” will familiarize students with the basic methods of process control, systemic and statistical analysis applicable in the management of an organization and subordinate processes. Students will also understand the rules for the identification of processes and the selection of statistical variables for serial and piece production processes. Students will master the rules of data collection and sorting, as well as the analysis and use of data for statistical process control.
Learning outcomes of the course unit
The subject “Statistical Process Control” allows students to gain knowledge of methods of statistical process control as a part of the comprehensive quality management of a company. Students will also master the identification of processes suited for statistical control. They will learn to apply individual methods of statistical quality control when solving problems which may arise in manufacturing companies as well as service providers. Students will also learn to identify key and supporting processes, and to apply the methods of statistical quality control in practice.
Knowledge of technology and materials. Knowledge of physics and applied statistics. Knowledge of quality management.

Planned learning activities and teaching methods
The course is taught through lectures explaining the basic principles and theory of the discipline. Seminars are focused on the practical application of the topics presented in the lectures.
Lectures by industry experts and excursions to companies focused on activities related to the course content will be included when possible.
Assesment methods and criteria linked to learning outcomes
Course unit credit requirements: Active participation in seminars, and the submission and presentation of analyses as assigned by the teacher.

The first goal of “Statistical Process Control” is to familiarize students with the basic statistical methods of process control. Another goal is to teach students to use the fact that real processes have a stochastic character, thus the rational approach to their management requires the application of statistical methods. The third goal is to teach students to apply statistical process control tools to standard and specific company processes and to devise appropriate improvement measures in the context of improvements to the quality management system.
Specification of controlled education, way of implementation and compensation for absences
Attendance in lectures is recommended. Attendance at seminars is compulsory. In the case of an excused absence, the teacher may decide on an appropriate substitute assignment.
