Design-by-computer is a viable design technique for general engineering design due to the availability of large-scale digital computers for engineering applications.
In the design-by-computer concept, the designer inputs the specified operating characteristics for the component or system to be designed, and the program will output the dimensions of the design parameters required to meet these specifications.
Hundreds of designs can be computed in minutes. This frees the engineer to improve his design methodology, analysis, and engineering decision-making criteria. This is used to improve the design synthesis process of the design-by-computer digital program.
