A General Model for Periodic Chemical Production Scheduling
journal contribution
posted on 2019-12-14, 18:03 authored by Yaqing Wu, Christos T. MaraveliasWe present a general mixed-integer programming model
for periodic
production scheduling. The formulation, which is based on the state-task
network (STN) representation, allows us to model (1) accurate inventory
levels, (2) various inventory policies, (3) different demand patterns
and profiles, and (4) flexible assignment of tasks to units. We first
develop a model for batch processes and extend it to handle continuous
processes. The model addresses all the limitations of previous approaches
to periodic scheduling and allows us to address various types of periodic
scheduling problems. Finally, we demonstrate the performance of the
model when applied to different types of processes through several
case studies.
