Through management science, businesses are able to solve a variety of problems using different scientific and mathematical approaches. Queueing analysis is the probabilistic analysis of waiting lines, and thus the results, also referred to as the operating characteristics, are probabilistic rather than deterministic. [5]
The mean sojourn time (or sometimes mean waiting time) for an object in a dynamical system is the amount of time an object is expected to spend in a system before leaving the system permanently. This concept is widely used in various fields, including physics, chemistry, and stochastic processes, to study the behavior of systems over time.
Circular wait: each process must be waiting for a resource which is being held by another process, which in turn is waiting for the first process to release the resource. In general, there is a set of waiting processes, P = { P 1 , P 2 , ..., P N }, such that P 1 is waiting for a resource held by P 2 , P 2 is waiting for a resource held by P 3 ...
This allows all of the waiting customers to know how many people are still ahead of them in the queue or line. Like this system, a ticket lock is a first in first out (FIFO) queue-based mechanism. It adds the benefit of fairness of lock acquisition and works as follows; there are two integer values which begin at 0.

The basic idea is that in situations where a system must wait for something to happen, rather than waiting indefinitely, the waiting will be aborted after the timeout period has elapsed. This is based on the assumption that further waiting is useless, and some other action is necessary.
The WAIT-II standardisation also includes several special group studies including those with learning difficulties, ADHD, emotional disturbance, hearing impairments, speech and language impairments and those who are classed as gifted. The WIAT-III US was standardised on 3,000 students and adults aged 4–19:11.
