Quality and Reliability


1. General Information

This course is among the general courses which have as aim to prepare the future engineers to design / produce quality produces / services adequate to the common European market. Both course and practical works make possible to present specific techniques to assure and certify the quality of products and services.

Course objectives: Teaching of fundamental concepts concerning quality, reliability and security engineering applicable in electronics and telecommunications. We will consider modeling and analysis of quality, reliability and safety / security of electronics and telecommunications systems (ETS), considering the design, fabrication and using; an approach based on faults / errors physics and of statistical instruments for ETS performance evaluation will be considered.

Applications objectives: Presentation of basic methods to be used in reliability laboratories of different companies for the evaluation of quality and reliability indices adequate to ETS.
