Queueing Theory Calculator

Formula (M/M/1 Model): Utilization $\rho = \frac{\lambda}{\mu}$, Average number in system $L = \frac{\lambda}{\mu - \lambda}$, Average in queue $L_q = \frac{\lambda^2}{\mu(\mu - \lambda)}$, Waiting time in system $W = \frac{1}{\mu - \lambda}$, Waiting time in queue $W_q = \frac{\lambda}{\mu(\mu - \lambda)}$. Enter arrival rate ($\lambda$) and service rate ($\mu$) below.
