1. A computer-implemented method of conducting sequential simulation operations utilizing a computer-based system model, the computer-implemented method including: performing a first simulation operation utilizing the computer-based system model to generate output data for a plurality of model parameters; attributing delta data to at least a first model parameter of the plurality of model parameters, and maintaining the output data for at least a second model parameter of the plurality of model parameters, thereby to generate input data for the plurality of model parameters; and performing a second simulation operation utilizing the computer-based system model and the input data for the plurality of model parameters, wherein the first and second simulation operations are performed sequentially as a continuous simulation exercise, and wherein the delta data is automatically attributed to the first model parameter of the plurality of model parameters after the expiration of a specified time period and before conclusion of the continuous simulation exercise.
