1. An integrated evaluation and simulation system for a weapon system having a plurality of elements including at least one munition element, comprising:

  • a computer system programmed to implement a causal network model comprising an integrated collection of analysis models representing a model-based description of the weapon system at a subsystem and component level resolution, individual elements of the weapon system being configured as nodes in the casual network suited to model complex interactions and interrelationships with other nodes, including operational and lower-level requirements, system performance and design attributes, and constrained resources, each node including at least one dynamic parameter for creating a virtual representation of the weapon system, a control system operably coupled to said casual network, said control system adapted to control at least one state and at least one mode of operation of said interrated evaluation and simulation system and to control an optimization process that operates upon said casual network model, said mode including a single-run mode, a dependencies mode, and a sensitivities mode, said single run mode adapted to propagate selected inputs once through the casual network model to produce a set of intermediate and final results, the single run mode further adapted to provide for the changing of one or more of said selected inputs during operation;

    said optimization process capable of determining a best set of design parameters that satisfy specified performance requirements and resource constraints, from among a set of user selected design parameters while causing an optimization of a weapon system'"'"'s combat effectiveness as measured by loss exchange ratio computations, said dependencies mode, for rapidly and visually identifying at least one interrelationship between design attributes and performance parameters within the casual network model by providing for a display of performance parameters affected upon a change to a user selected input value;

    said sensitivities mode adapted to evaluate weapon system performance in terms of one or more design parameters in the causal network model by providing for the evaluation of effects on one or more performance parameters upon varying a user selected design parameter;

    at least one virtual simulation system operably coupled to said causal network model and said control system by a virtual simulation system interface, said virtual simulation system interface serving as a conduit between said causal network and said virtual simulation system, the virtual simulation system interface adapted to return data structures from the virtual simulation system to the control system, said virtual simulation system adapted to simulate said weapon system, including a simulation of a lethality of the at least one munition element; and

    a user interface operably coupled to at least said computer system to selectively input data into and receive information from, one or more of said causal network model, said control system and said virtual simulation system interface.
