bottlenecku
Bottlenecku is a term used in systems theory and operations research to describe a bottleneck unit within a process network whose throughput constrains the entire system. Unlike a fixed bottleneck, bottlenecku captures the dynamic emergence and movement of the limiting node as workload, routing, and resources change. The concept is common in simulation and performance analyses, where a single component can govern the overall pace of a pipeline even when other parts have ample capacity. It emphasizes the context-dependent nature of bottlenecks in complex systems.
The term is a neologism used in contemporary literature to stress unit-level fragility rather than a permanent
Key characteristics include dynamic location, scale dependence, and sensitivity to scheduling. A bottlenecku arises when a
Measurement and detection involve monitoring utilization, queue lengths, and cycle times over time, using flow models
Mitigation strategies include targeted capacity expansion, load balancing and routing, buffering to smooth bursts, process redesign,
Limitations include definitional ambiguity and dependence on objectives and horizons; identifying bottlenecku can be sensitive to
