US Patent 11385625 Flow control system and control method therefor

This flow control system is obtained by connecting a plurality of work units WUα and a plurality of work units WUβ to one another, wherein: each WUα has an α-control purpose which is a WU-based independent control purpose, and has an α-control rule for the α-control purpose; each WUβ has a β-control purpose to cause as many WUα as possible to achieve the own α-control purposes, and has a β-control rule for the β-control purpose; the β-control rule is dynamically changed on the basis of partial information about the flow control system; and the WUβ is disposed in a part of the flow control system.
