1. A method for modifying a design of a complex system, the steps of the method performed by a data processing expert system having a memory, comprising:

  • storing in said memory input design characteristics data provided by a designer of said complex system that represents an initial version of said design of said complex system;

    processing said input design characteristics data to simulate the operation of said design thereby producing a plurality of simulated operational characteristics data of said design, said plurality of simulated operational characteristics data stored in the memory;

    comparing the simulated operational characteristics of the design with a plurality of desired operational characteristics stored in the memory as provided by the designer of said complex system and identifying causes of discrepancies between said simulated operational characteristics of said design and said desired operational characteristics as provided by said designer;

    storing a set of operators, in said memory for performing redesign operations on a plurality of components of the complex system, to generate a redesign of said complex system; and

    redesigning said complex system by causing said operators to perform said redesign operations in a selected sequence on said plurality of components.
