ABSTRACT
In general, engineering designers work only within a certain limited range of technical process (TP) and technical system (TS), a branch of engineering. Their involvement is with one particular TS-“sort”; see Section 6.11.10. Their knowledge must include TS of lower complexity (see Figure 6.5) that provide constructional parts, and often to TS of higher complexity in which “their” TS find application. The information presented in this chapter is mainly situated in the “north” hemisphere of Figures I.4, I.5, and 12.7.
