Have a look at the nomograph in this paper: http://eetd.lbl.gov/ie/pdf/LBNL-1519E.pdf http://eetd.lbl.gov/ie/pdf/LBNL-1519E.pdf The anthrax attacks in the fall of 2001 brought to light a number of uncertainties about how to tell whether a building is clean enough to re-occupy (How effective is sampling? What's the anthrax dose-response curve look like? What's the distribution of spores in a building?, etc.). As part of his investigation, a colleague of mine constructed the nomograph in this paper, to illustrate the tradeoffs involved. By presenting the uncertainties graphically, the nomograph helps visualize the tradespace, in a way that simply running multiple numerical calculations won't necessarily do. By the way, this also shows that these are not an entirely lost art.
