Patent ID: 7315805

Claim:
A computer-implemented discrete event simulation (DES) system for the operations and support (O&S) problem of a weapons system, said DES system comprising: a plurality of dynamic objects having attributes that represent characteristics of weapons, said attributes having local values that define a local state of each dynamic object; a plurality of static objects having data that is global with respect to the dynamic objects and functional operators, at least some of which are probabilistic; a network of said static objects that are organized in accordance with a service use profile (SUP) to calculate a time-based prediction of weapons stockpile and operational availability, maintenance activities, and spare parts stock over a life cycle of the weapons system, said network having a global state; and a simulation engine that advances to the next change of said local or global states whereat said static objects read and write said attributes in accordance with their functional operators and global data and update the time-based prediction of weapons stockpile and operational availability, maintenance activities, and spare parts stock as the dynamic objects traverse the network, said DES displaying the results of the simulation including the time-base prediction of weapons availability, maintenance activities and spare parts stock to a user through an interface to maintain an inventory of said weapons over the life cycle of the weapons system.
