Description
Tackle challenging optimization problems with MATLAB (R) software
Optimization techniques measure the minimum or maximum value of a given function depending on circumstances, constraints, and key factors. Engineering processes pertaining to design or manufacture involve optimization techniques at every stage, designed to minimize resource expenditure and maximize outcomes. Optimization problems can be challenging and computationally intensive, but the increasingly widely-used MATLAB platform offers numerous tools enabling engineers to tackle these essential elements of process and industrial design.
Chemical Engineering Analysis and Optimization Using MATLAB (R) introduces cutting-edge, highly in-demand skills in computer-aided design and optimization. With a focus on chemical engineering analysis, the book uses the MATLAB platform to develop reader skills in programming, modeling, and more. It provides an overview of some of the most essential tools in modern engineering design.
Chemical Engineering Analysis and Optimization Using MATLAB (R) readers will also find:
Case studies for developing specific skills in MATLAB and beyond
Examples of code both within the text and on a companion website
End-of-chapter problems with an accompanying solutions manual for instructors
This textbook is ideal for advanced undergraduate and graduate students in chemical engineering and related disciplines, as well as professionals with backgrounds in engineering design.
