ABSTRACT
Reliability-based logistical economic analysis is a subset of integrated logistical support analysis. Integrated logistical support analysis investigates the entire supply chain for a part from the manufacturer through all transportation and distribution points to the end user. Reliability-based logistical economic analysis applies the reliability math models to logistical events that are directly associated with part failure. Part level logistical economic analysis investigates the resources associated with part repair and system logistics downtime. The resources include labor skills mix, labor allocation to a task, maintenance planning, spare parts inventory, access to facility bays, and specialty tools, to name a few. Recall that all sustainability costs are caused by part failure. Part logistical economic analysis characterizes the sustainability costs. Remember costs occur at points in time: present amounts, uniform recurring amounts, and future amounts. Reliability analysis defines when sustainability costs will be incurred, mean time between failures (MTBF), the magnitude of the costs, and the duration of the cost events. The integration of reliability analysis with part logistical economic analysis is illustrated in Figure 5.1.
