jonokokoihin

Jonokokoihin is a term used in theoretical discussions of crowd organization to describe the phenomenon whereby a single service line or queue splits into multiple subqueues. The concept is used to analyze how people self-segregate to form groups that they perceive will affect waiting times, service order, or social signaling. The term appears mainly in academic writings and informal observations rather than formal standards of queueing theory.

Etymology: The coinage blends Finnish jono meaning “queue” and koko meaning “size,” with the illative plural ending -ihin, yielding “to the sizes of queues.” The term is not widely standardized across languages, but is sometimes used in cross-cultural discussions of queuing behavior and crowd dynamics.

Mechanisms and contexts: In physical lines, signage, barriers, and staff guidance can cause customers to form visible subqueues pinned to differentiated service counters or languages. In digital environments, users might join different streams or ticket categories within a single system. Social cues, perceived fairness, and the expected duration of service influence how people self-divide, sometimes creating nested or hierarchical queue structures that persist even when overall wait times are similar.

Measurement and modeling: Researchers measure subqueue distributions, average waiting times, and perceived fairness. Agent-based models and multi-server queueing models are used to simulate how changes in layout, information presentation, or staffing alter jonokokoihin dynamics. Field data from retail, healthcare, and transit settings can help validate these models.

Implications: Understanding jonokokoihin can help designers reduce perceived unfairness and optimize resource allocation, though it can also lead to greater segmentation and opacity in service flow, potentially harming overall system transparency.
