D. Ko et al., Development of a batch manager for dynamic scheduling and process management in multiproduct batch processes, KOR J CHEM, 17(1), 2000, pp. 27-32
A batch manager is developed for the dynamic scheduling and on-line managem
ent of process operations. The developed system consists of a process monit
oring module and a dynamic scheduling module. When a deviation from the ini
tial schedule is detected in a process monitoring module, dynamic schedulin
g is performed in the dynamic scheduling module and the initial schedule is
adjusted to the proper schedule by using rescheduling algorithms presented
in this paper. The adjusted schedule is shown in the process monitoring mo
dule. The dynamic scheduler in the batch manager copes with several unexpec
ted process events of batch process operations by adjusting the EST (Earlie
st Start Time) of equipment, redetermining the batch path and reassigning t
asks to equipment. This study focuses on the implementation of a batch mana
ger with on-line dynamic scheduling for batch process management. Examples
of fodder production batch processes illustrate the efficiency of the algor
ithms.
