[Question] Call Prediction and Erlang C ?

Hello,

I’m using KNIME 5.2.0 but I’m not expert.

I am working at a call center company and we would like to make a monthly call forecast and determine the number of representative needed. It takes a lot of time when doing it with Excel, so I want to do it via knime.

1. How can I predict calls in the coming months by looking at past data? (I have historical data)

2. How can I determine the number of staff needed using erlang c?

3. How can I predict the SL value that may occur?
