Editorial : Planning and Scheduling in Complex Systems

To be competitive in the global market and provide flexibility in today’s high-mix-low-volume environment, various industrial sectors have moved complex systems away from the old style fixed hardware with sequential schedules on dedicated tools. The agility provided by the capacity of a complex system to be quickly reconfigured to provide new products and services relies mainly on how efficiently and rapidly engineers can schedule, reschedule and re-plan tasks and processes in the system. Design and analysis of high and intermediary (planning and scheduling) levels of supervision are in the focus of this issue. A computer-based supervisory controller, as the major component of these two levels, monitors the statusof jobs and services, schedules matter, energy and information routing and plans equipment operation selection. Rapid prototyping, high level of quality of service, and fast growth of networked control systems require new approaches to the design of planning and scheduling algorithms employed in complex system supervisory controllers.
