Cost Effectiveness Analysis of Complex Repair Processes Using Graphical Evaluation Review Technique (GERT)

Abstract

This paper presents an approach to analyzing the costs attributable to sources of errors in complex multi-level repair processes which have many feedback loops and branching points. It is shown how computer simulation of such processes can be useful in identifying those general areas or subprocesses, which would, if improved slightly, result in major improvements in cost effectiveness. A hypothetical repair process is presented in the paper and is used to demonstrate a method of analyzing the costs associated with errors that are committed in the hypothetical process. The computer simulation technique which is used is called Graphical Evaluation Review Technique (GERT), which has been developed by A. A. B. Pritsker. The technique offers the basic advantage exploiting a canned FORTRAN 4 simulation program called Q-GERTS.
