Abstract: In this contribution we present an online scheduling algorithm for a real world
multiproduct batch plant.The overall mixed integer nonlinear programming (MINLP) problem is
hierarchically structured into a mixed integer linear programming (MILP) problem first and
then a reduced dimensional MINLP problem, which are optimized by mathematical programming
(MP) and genetic algorithm (GA) respectively. The basis idea relies on combining MP with GA
to exploit their complementary capacity. The key features of the hierarchical model are
explained and illustrated with some real world cases from the multiproduct batch plants.

Key words: online scheduling, multiproduct batch plant, mixed integer nonlinear programming, mathematicalprogramming, genetic algorithm
