On The Critical Path Method (C.P.M) and its Application in the G.D.R

Network models and methods are used above all for flow and time planning of complex processes. In each case the pre- paration of decision is based upon certain problems of sequence. On principle always such processes or systems are concern- ed in which partial processes flow simultaneously or successively. That means on the one hand that a simultaneous flow of different partial processes (parallel flow) is given and on the other hand that partial processes may only begin, if proceeding ones are completed (flow in series).
