Overall process cost with variation in performance of cell harvesting technologies. The contour lines denote the viable region for the three technologies available for cell harvesting: centrifugation, filtration, and sedimentation. They are horizontal in the region where filtration is selected, whereas they are vertical where centrifugation is selected. The constant color rectangular region [(70,70), (70,82), (77.5,82), (77.5,70)] denotes the selection of sedimentation. Critical values, when there is a change in technology selection from centrifugation to filtration or sedimentation, are shown by white lines
