Abstract

It is regularly to optimization of temperature and feeding profiles in batch process for several objectives and constraints. A temperature profile is applied to drive the process so as to obey certain constraints during the beer fermentation. The design of this temperature profile is an optimization problem where the objective is to minimize the operation time and optimize the quality of beer. In this paper, differential evolutionary computation is exploited to efficiency handle such problems. The proposed approach has been implemented and practical to design temperature profile for beer fermentation process. The results show that differential evolution is a proficient and at ease method to incorporate the prior knowledge of the user into the temperature profile optimization of batch processes.
