why do you think simulation theory only came about in the early 2000’s. I used simulation theory in the 1970s to simulate a number of things including:
Financial investment analysis based on risk assessment.
Mine planning.
Nuclear reactions.
Analysis of complex chemical plants that produced a number of products from a variety of feedstocks that interacted with each other.
We called it computer modelling back then but the concepts of simulation theory were already well established.
