How simulation test help the market research?

I am thinking when a company conducts marketing research for one existing product by different methods such as customer interview, survey, etc. Each method shows different result. How we can combine those results to come up with the final one? Can simulation test help in this method? When we use different parameters for simulation, how can we extract the result from the market search to test the simulation?

Hereunder is the diagram supporting the simulation but I don`t know how effective it is for market research?


Thanks,
