Certain Application of GERT Network Analysis in Statistical Quality Control

Graphical Evaluation and Review Technique commonly known as GERT, is a network analysis technique effectively used in project management that allows probabilistic treatment of both network logic and estimation of activity duration. The technique was first discovered in 1966 by Dr. Alan B. Pritsker of Purdue University. Compared to other techniques, GERT is rarely used in complex systems. The GERT approach, addresses the majority of limitations associated with PERT/ CPM technique. The fundamental drawback associated with the GERT technique is the complex programme required to model the GERT system. Development in GERT includes Q- GERTS allowing the user to consider queuing within the system. Graphical Evaluation and Review Technique has been applied in modeling of sampling plans and promises to be value in encouraging statistical quality control. In this paper we analyze a sampling plan using GERT technique.
