DailyDirt: Waiting In Line Isn't Fun
from the urls-we-dig-up dept
Queuing theory is a subset of applied math that looks into the behavior of waiting in line and algorithms that optimize various aspects of this particular kind of resource allocation. Retailers of all kinds are interested in this kind of math because it can improve customer satisfaction and get more products out the door. Apple reduces long cashier lines with employees who can accept payments anywhere in its stores. Fry's Electronics has the giant single line that feeds into a massive array of cashiers (aka the serpentine line). There are self-checkout lanes at the grocery store, but there's no silver bullet to eliminate waiting in lines. Here are just a few more links on this problem of civilization.- Ever pick a checkout line at the grocery store and think "I always pick the slowest lane" once you've committed to a particular cashier? The math says that the odds of picking the fastest lane are against you, so you're most likely right that you never pick the fastest line. [url]
- Waiting in line at Disney can be cut short with its Fastpass system, but what does Fastpass really optimize? FYI, Disney doesn't let you hire disabled kids to cut in line anymore. [url]
- The best system for boarding planes is not the one that most airlines use, but Southwest's boarding method does pretty well. A few studies have looked at how to board planes more efficiently, but the Jason Steffen method isn't used by any airline (and there's little incentive for most airlines to change what they're currently doing).

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

Line logic
Trader Joes seems quicker on the whole, though it offers numerous opportunities for impulse purchases as you pass various shelves, which may be why they do it.
But there must be a line of reasoning which proves one quicker than the other....
