Abstract
This thesis describes a simple-to-use, multi-echelon, single-item, simulation model written in SLAM II. The model simulates the operation of Recoverable Items (RIs) at one or more bases and the flow of supporting RIs through a multi-echelon maintenance system. The model can be configured by the user to simulate a system consisting of one to three maintenance echelons with one to six bases. Lateral resupply is also an option. The model uses an (s-1,s) inventory policy. The model calculates several performance measures including operational availability, mean supply response time, and time-weighted backorders. The operating time for each RI is a exponential random variable. The mean failure rate is input by the user and may be different for each base. Each maintenance echelon has a single queue where failed RIs wait for an available maintenance stationserver. Each echelon can have any number of servers as determined by the user. The default distribution for repair time is the lognormal but other distributions can be used. The shipping times between all bases and echelons are also determined by the user.
