Abstract

The operational impact of logistics information systems design needs more attention. The evaluation of systems reliability from engineering or operations management perspectives and the analysis of information systems effectiveness are often two independent activities. While most systems spend the majority of their lifecycle in the sustainment or maintenance phase, not enough is done to incorporate administrative and logistics support systems performance in the reliability analysis of the design of engineering systems. This study extends on prior work conducted which established that maintenance philosophy and procedures are contributors to the operational availability of deployed military systems. Using data from real-world systems and established reliability-analysis processes such as Reliability Block Diagrams (RBD), this study developed a simulation model to conduct a causal-comparative experimental study on the impact of logistics information systems design on the operational availability of the systems they support. The study used a Monte Carlo simulation to conclude that the information systems design has a significant impact on operational availability.
