Practical Optimization pp Cite as. Throughout the ages, man has continuously been involved with the process of optimization. In its earliest form, optimization consisted of unscientific rituals and prejudices like pouring libations and sacrificing animals to the gods, consulting the oracles, observing the positions of the stars, and watching the flight of birds. When the circumstances were appropriate, the timing was thought to be auspicious or optimum for planting the crops or embarking on a war.
The Optimization Problem
This paper introduces and describes a novel software tool to analyze and solve optimization problems. This tool allows the plotting of several functions simultaneously, navigates through them, and finds the critical points with several numerical methods. Depending on the problem the user can choose a context in two or three dimensions and can also select the more convenient method to solve a specific problem. Moreover, the parameters modification in a particular method is transparent and clear; the goal of this software is to simplify the work of students, engineers and researchers, working on a graphical and interactive environment, on a completely intuitive user interface. Nowadays it is almost required to obtain the best results in any given situation in most areas of science. In this sense, optimization is a way to obtain such results.
One common application of calculus is calculating the minimum or maximum value of a function. For example, companies often want to minimize production costs or maximize revenue. In manufacturing, it is often desirable to minimize the amount of material used to package a product with a certain volume. In this section, we show how to set up these types of minimization and maximization problems and solve them by using the tools developed in this chapter. The basic idea of the optimization problems that follow is the same. We have a particular quantity that we are interested in maximizing or minimizing.

Mathematics Educators Stack Exchange is a question and answer site for those involved in the field of teaching mathematics. It only takes a minute to sign up. Our students are not fencing in farm fields, cutting wires and folding them, or designing windows, so they are often uninspired by the optimization problems we give them. They seem like something that "someone, somewhere" might use, but the examples feel distant. What are good examples of constrained optimization problems perhaps not simple! If your goal is to find problems that are more easily accessible, see also the sister question What are easy examples from daily life of constrained optimization?
Here, we use the method of 28 to solve optimization problems. Example Solution The quantity to be maximized is the volume V of the box, which is.
3.6: Applied Optimization Problems
Practice Quick Nav Download. You appear to be on a device with a "narrow" screen width i. Due to the nature of the mathematics on this site it is best views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width.
Optimization is a tool with applications across many industries and functional areas. To learn more, sign up to view selected examples online by functional area or industry.
In Section 3. In this section, we apply the concepts of extreme values to solve "word problems," i. We start with a classic example which is followed by a discussion of the topic of optimization. A man has feet of fencing, a large yard, and a small dog. He wants to create a rectangular enclosure for his dog with the fencing that provides the maximal area. What dimensions provide the maximal area? One can likely guess the correct answer -- that is great.
In business and economics there are many applied problems that require optimization. For example, in any manufacturing business it is usually possible to express profit as function of the number of units sold. Finding a maximum for this function represents a straightforward way of maximizing profits. It has a maximum at the following point:. Investigate extreme values of the profit function.
Section Optimization. Find two positive numbers whose sum is and whose product is a maximum. Solution; Find two positive numbers.
