I am currently doing an uncertainty analysis for my product system by using Monte Carlo. To do this I removed all uncertainty from the ecoinvent database and thus when I currently run the Monte Carlo I only get one value with no standard deviation. However, this one value is VERY different from the results I get from Quick results, which does not make sense. Should I not get the same value from quick results and Monte Carlo when there is no uncertainty in my system? It seems I get the same value when using Cut-Off but not when using Consequential database, but I cannot see what should make one work and not the other. I have attached pictures for a random ecoinvent process - one being results from the Monte Carlo and the other is the quick result for the same process.
