Overall robust optimization of biopolymer synthesis with linear electron accelerators

The process of electron beam grafting is implemented for the production of highly efficient graft copolymers from natural polysaccharides and regulating their properties for application as flocculating agents during the treatment of different wastewaters. In this paper, the electron beam induced modification of corn starch by grafting of acrylamide is performed in two linear electron accelerators with mean energies of 5.5 MeV and 6.23 MeV. The implemented methodology for the multi-criteria parameter optimization is the overall Robust optimization approach, based on the overall desirability function. The proposed approach involves the definition of different weights for the mean and the variance overall functions, as well as different weights for the individual desirability functions that take into account the prediction accuracy of the estimated neural models.
