title: Performance evaluation of ethanol fermentor systems using a vector-valued objective function.
abstract: It is shown that the performance evaluation using a vector-valued objection function whose components are the product productivity, the product concentration, and the substrate conversion is quite useful in getting deeper insight into the development of new processes and in determining the operating point. Particular attention is focused on the ethanol fermentation using variety of systems such as the conventional chemostat system, multiple fermentor system, cell recycle system, extractive fermentor system, cell recycle system, extractive fermentor system, and immobilized cell system. The contour map and the projection of the noninferior set are used in investigating the performance improvement and the trade-offs among performance indexes.
