Simulation model to evaluate maintenance strategies for large network of fielded systems

A dynamic simulation model of a field maintenance organization has been developed and validated. The objective of the model is to provide an analytical tool for evaluating the operational feasibility of new maintenance strategies prior to their introduction into the field. This simulation model is an accurate replica of the policies and time critical maintenance activities within a field organization, providing a rendering in detail of each technician and each facility as events take place in time. This paper discusses the structure of the model, the functions simulated, the validation experiment, and an application of the model.
