Through an illustrative case study, this article demonstrated how to use process simulation tools to assist in the evaluation
of process alternatives. Two options for buffer preparation and holding activities of a typical MAb process were analyzed
from an economic perspective. The first used single-use buffer preparation and storage bags, whereas the second used traditional
stainless-steel preparation and holding tanks. The single-use system proved to be more advantageous for smaller scales, whereas
the stainless-steel option becomes more economical as the production scale increases. The evaluation results are specific
to the MAb process analyzed. Additional process options and alternative technologies can be readily evaluated and compared
using such tools.
