8. PIECEWISE LINEARIZATION 8.1 INTRODUCTION Most water resource planning and/or operation problems can be expressed in terms of linear con-straints. Mass balance or limits on resource use, for example, are generally linear functions. Many objective functions, however, tend to be non-linear. Design problems for which the

functions that contain discontinuities). Before that could be done, we need to learn how to find the Laplace transforms of piecewise continuous functions, and how to find their inverse transforms. Our starting point is to study how a piecewise continuous function can be constructed using step functions.

Piecewise-Defined Linear Function: Given non-overlapping intervals on the real number line, a (real) piecewise linear function is a function from the union of the intervals on the real number line that is defined by (possibly different) linear functions on each interval. or Lesson 1: Graphs of Piecewise Linear Functions Date: 5/25/14 S.2

Piecewise-Linear Programs Several kinds of linear programming problems use functions that are not really linear, but are pieced together from connected linear segments: These ‘‘piecewise-linear’’ terms are easy to imagine, but can be hard to describe in con-ventional algebraic notation. HenceAMPL provides a special, concise way of ...
