Evaluation of Technical Systems

Abstract

At the beginning of chapter 7, the question “how is the car?” was asked. This question implied “what qualities does it have, what properties and their measures, what performance?” In order to answer this question, certain properties must be selected and evaluated, and the resulting (possibly large) number of measures must be combined into a commonly understood characteristic value. Combining measures is not easy, especially if we are dealing with different properties such as speed, power, equipment in the passenger compartment, appearance, surface hardness and others. Only if such a meaningful combination, a synthesizing characteristic can be achieved can we objectively assert that one car is better than another, because it has a higher characteristic value. Some of the problems of evaluating a TS were the subject of section 7.4.
