Abstract : Applied network theory and marginal analysis concepts were utilized to design, computerize, verify, and evaluate, three major software modifications to the Network Repair Level Analysis (NRLA) model, First, a preprocessor subroutine using marginal analysis techniques was developed and tested to reduce the computer processing requirements of the program. Second, a new network labeling algorithm which solve the max-flow min-cut problem is presented. This algorithm performs 100 times faster than the current algorithm and 73 times faster than the highly efficient, commercially available, primal networking code known as GNET. Third, for the first time a networking structure has been designed which allows for the inclusion of Centralized Intermediate Repair Facilities (CIRF) in the repair level analysis decision process. The NRLA program is hosted on the CREATE Operating System and contains approximately 5500 lines of computer code. It consists of a main routine and twelve major subroutines. The results from the NRLA model are used by logistical planners to quantify the potential cost impacts associated with alternative maintenance plans. As the technological complexity of weapons systems has increased new and innovative logistical support systems are required to maximize the system's operational capability while minimizing life cycle costs.
