Acquiring method and system of queuing wait time

The invention provides an acquiring method and system of queuing wait time, which are suitable for the technical field of control. The acquiring method of the queuing wait time comprises the following steps of: acquiring the average arrival rate of customers and the average service rate of a service desk, and respectively recording as lambda and mu; acquiring the state transition information of the customers according to the average arrival rate of the customers and the average service rate of the service desk, wherein the state transition information of the customers accords with state transition equations of the customers; analyzing and calculating the state transition equations of the customers to acquire the wait time of the customers, and outputting and displaying. Through the embodiment of the invention, the accurate queuing wait time for the customers is acquired by acquiring the average arrival rate of the customers and the average service rate of the service desk, acquiring the state transition information of the customers, which accords with the state transition equations of the customers, according to the average arrival rate of the customers and the average service rate of the service desk, analyzing and calculating the state transition equations of the customers to acquire the wait time of the customers and outputting and displaying, and therefore, the satisfaction degree of the customers is enhanced.
