Single-channel Queuing Model

Note about lambda and miu.

1. Lambda and miu must be expressed as something per time, not time per something. (Example: 5 customers per 10 minutes, 1 customer per 6 minutes).

2. Unit of time for both lambda and miu must be the same and must be per 1 unit of time (per 1 hour, or per 1 minute, or per 1 second).
