For the queuing task I explored an everyday life problem. While dancing in a club you get thirsty and you want to get a drink. There are 2 bars, one with 10 people standing in a row and one with 10 people creating a crowd and are “fighting” to get a drink. Which bar should I choose?
Regarding to a SPIEGEL article scientist Refael Hassin (iniversity of Tel Aviv) says the crowded bar is the better one. While you know in a sorted queue you will be the eleventh one, in the crowded bar you have a good chance to get your drink earlier.
The hardest thing to calculate is in every situation the influence of the luck/chance, which makes every case complex. Regarding to our students perspective this can be a damage of an airplane you wanted to use or if in the queue of your supermarket someone wants to return a product.
A solution of the supermarket queue already exists. According to the scientist Alexander Herzog (University Clausthal) only one big queue instead of many small queues (Multi-Queues) is the smartest way. The system is used at German Post, or at airports.
