The introduction doesn't appear in table of content. How I can do it in the following example.

\documentclass{book}
%\usepackage{graphicx}
\usepackage{tcolorbox}
\usepackage{setspace}
\renewcommand{\baselinestretch}{1.0}
\title{Operation research}
\author{Dr.C. Andrey Vinajera-Zamora}
\begin{document}
\tableofcontents
\maketitle
\chapter*{Introduction}

\chapter{Operation research}
the operation research is ....
\section{Lineal Programming}
The lineal programming is considered
\chapter{Solution methods}

\end{document}


Use \frontmatter and \mainmatter.

EDIT: here is a full solution for your additional questions using \setcounter, etc.

• this example put the table of contents before title and the page number must begin with introduction. – Andrey Vinajera Apr 25 '18 at 15:09
• It put TOC before title because that's how you set it up. Just switch them. The page numbering technically is a separate question, but that answer is easy to find. – AML Apr 25 '18 at 15:21
• I have fixed all your additional issues in the edited code above. – AML Apr 25 '18 at 15:32
