For additional background the reader may wish to refer to BUSACKER, SAATY [1], ELMAGHRABY [4], NEUMANN [13], and WHITEHOUSE [25].

Many projects, however, for which the time planning is to be carried out by means of GERT networks do not satisfy this restriction.

Allgemeines: Aufgaben der Meteorographen,herefore to be preferred to this evaluation procedure. A simpler version of this procedure suffices to determine so-called “non-genuine” IOR nodes and to replace them by EOR nodes, as is necessary, for example, in order to apply the BES method from chapter 3 (compare convention (3.1.2)). This will be discussed in section 4.4.
