Question

In Poisson systems where this action is performed, the expected value of an observation at a certain time is equal to the long-term average in a property abbreviated PASTA. Systems of this action that have a product-form solution include closed Jackson networks, according to the Gordon-Newell theorem. People performing this action can engage in “jockeying” and “reneging” (“ruh-NEG-ing”), and not doing this action is called “balking”. This action is modeled by a notation that consists of two letters and a number separated by slashes, such as (15[1])(*) M/M/1 or M/G/1. (10[1])A. K. Erlang invented the field of studying this process, based on his observations of telephone callers performing this action. The “virtual” form of this action is implemented by the take-a-number system used by many government facilities. (10[2])For 10 points, name this action that shares (10[1])its name with a first-in-first-out data structure. ■END■
