​EADSIM provides a robust reliability, availability, and maintainability (RAM) modeling, to include multi-day scenarios. This RAM modeling allows specified components of a system to fail based on a mean-time-to-failure statistical distribution. Each component has a mean-time-to-repair, also specified by a statistical distribution, and a user specified inventory of spare components that can be drawn from as a remove-and-replace (R&R) process. R&R times are also specified as a statistical distribution. In all cases where distributions are used, the type of statistical representation is user selectable. Depot ordering with shipping delays for individual components is also captured in the RAM modeling.
