# Manipulate coupled with QueueProperties

I am trying to couple Manipulate with QueueProperties and it does not seem to work. It creates the manipulate screen but it is not dynamic. It just sits there.

Here is my example:

\[ScriptCapitalQ] = QueueingProcess[\[Lambda], 4.3, 1]


Manipulate[QueueProperties[\[ScriptCapitalQ]], {\[Lambda], 1, 4}]


and it creates the Manipulate framework, but lambda does not change dynamically and recompute the QueueProperties.

• With Manipulate[] you generally want to have your expression being a function of the parameters that you want to manipulate. E.g. try \[ScriptCapitalQ][\[Lambda]_] := QueueingProcess[\[Lambda], 4.3, 1] and accordingly Manipulate[QueueProperties[\[ScriptCapitalQ][\[Lambda]]], {\[Lambda], 1, 4}] – Sascha Jan 22 '16 at 19:50

As Sascha has note in a comment, you need to define your queueing process as a function of λ.
q[λ_] := QueueingProcess[λ, 4.3, 1]
