The continuously increasing demand on engineers to lower the production cost and elevate the profits has prompted engineers to look for various methods for decision making. One of the commonly used methods is optimization. Optimization is a process in which one tries to find out a condition that gives the maximum or the minimum of the function. Through optimization, any engineer can achieve his or her best to design and produce products which are economical and also at the same time prove to be efficient. The idea of optimization is widely used in industries, which includes aerospace, automotive, electrical, chemical, and manufacturing industries.
