I want to write equation below in LaTex:
I wrote it :
r_{i,j}=min\lbrace\vert x_{i,j}$\bigotimes$ K_{p} \vert \: p=1 to 4\rbrace\;
but it giving error.
Please give suggestion to write it correctly.

First, never use $\Pi$ when you obviously mean $\prod$. Second, I guess dots here between $R_i$ and $ID$ should be centered.
Here is what I got:
\documentclass{article}
\usepackage{amsmath}
\DeclareMathOperator{\Dist}{Dist}
\begin{document}
\pagestyle{empty}
\begin{displaymath}
MR(e) = \prod_{(R_i\cdot ID, R_j\cdot ID)}
\underset{\Dist_{sp}(r_i,r_j)\le\delta}{(R_i\bowtie R_j)}
\end{displaymath}
\end{document}
You would probably want to use an align environment
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
\label{cons1}
x_i+w_{mi}&\le X_j &&\text{if $i$ is to the left of $j$}\\
\label{cons2}
x_i-w_{mj}&\ge X_j &&\text{if $i$ is to the right of $j$}\\
\label{cons3}
y_i+h_{mi}&\le y_j &&\text{if $i$ is below of $j$}\\
\label{cons4}
y_i-h_{mj}&\ge y_j &&\text{if $i$ is above of $j$}
\end{align}
\end{document}
You shouldn't use eqnarray in LaTeX, see eqnarray vs align

The entire expression, and not just the
\otimesterm, must be in math mode:Note that I would use
\otimes, not\bigotimes. And, do write\minrather than justmin.Addendum: If you wanted to give more visual prominence to the curly braces that enclose the material to the right of the
=symbol, you could enlarge them a bit via\bigland\bigrmodifiers:
