How to use fit tikzpicture in a LaTeX file

Question

I use tkiz to draw a picture in LaTeX. It works with me with \documentclass[border=5pt,tikz]{standalone}. However, when I try to use the same code in my original LaTeX file \documentclass[english]{IEEEtran}, it does not fit in the paper. How can I edit the following code to use it in my LaTeX file?

\documentclass[border=5pt,tikz]{standalone}
\usetikzlibrary{arrows,positioning}
\newcommand{\parallelsum}{\mathbin{\|}}
\newcommand{\point}{\textbullet\hspace{1em}}
\everymath{\displaystyle}

I tried to redesign your picture and apologize in advance for all the mistakes I made, e.g. by breaking your formulae incorrectly.
