We develop tightening and solution methods for optimization problems containing bilinear terms. We focus on the bilinear termwith nonnegative variables \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$x\in \left[{x}^{\mathrm{L}},{x}^{\mathrm{U}}\right]$$\end{document} and, whereis semi-continuous and upper and lower bounded byandwhen positive.andare said to be nontrivial upper and lower bounds ifis smaller thanandis greater than, respectively. We derive a family of valid linear constraints and show that, when one of the nontrivial bounds is active, such constraints are tangent to one branch of the hyperbola that represents the bilinear term. We propose different preprocessing methods for generating strong constraints from the family. Computational results demonstrate the effectiveness of the proposed methods in terms of reducing optimality gap and computational time.
