Little’s Law & My Sandwich

This morning, while having breakfast (nice cup of coffee and a sandwich), it came to my mind the queueing theory (probably because yesterday, while driving to Valencia, I remembered one of the first chapters of Numb3rs, when Charlie uses this theory to explain a car accident).

Summarising, Little’s Law JUST (like if it was small talk) says is the average number of units in an stable system (when in the long-term), equals the long-term rate of arrival (gamma) times the long-term average time this unit spends on the system.


L = [gamma] x W


So, where else does my sandwich fits on this?.  Don’t you know?: my mouth can taste on average that many units related to the speed and pace of bitting, drinking, swallowing… but only if eating a sandwich could be considered as a long-term activity…
