- Title
Key Assumptions Used in the Calculation of Sustainability Parameters for Metals Processing Operations.
- Authors
Battle, Thomas P.
- Abstract
No matter how sophisticated a model for prediction of important sustainability parameters, a number of assumptions must be made to yield the desired information. Some of these assumptions are well understood, and stated clearly in the description of the particular model used. However, in many cases, assumptions are not clearly stated, or sometimes not even fully understood. Using a case study of calculations for different options in iron- and steelmaking, many of these overt (and covert) assumptions are presented and discussed. It is clear that, as a model is developed and used, all assumptions should be stated clearly, including an explanation for the use of a particular assumption and a particular value. Model developers should be especially wary of assumptions that might be buried in constants or conversion factors.
