Loop tracing in PEP-PERT networks
Joel M. Prostick · 1961
The problem of incorrect input data associated with most data processing applications is magnified in PEP-PERT systems because of the interrelation of the various events. When this incorrect input takes the form of a looping network, the result may be a halt in the computer program, often necessitating a manual search of the computer memory dump to determine the trouble. If a network has more than one loop this procedure must be repeated for each loop. This paper describes a method which has proved to be an excellent solution to this problem; it is a computer technique for editing a complete PEP-PERT network and describing any and all loops therein.
