1. What is production for final demand? If feasible, why is it more efficient than production for inventory?

Production for final demand, or BTO, is when once a confirmed order for products is received, products are built (not before). The more customizable a product (Dell computers) or the greater the loss in return on investment due to delay in sales, the more the product is a candidate for BTO.

If feasible, it is more efficient than production for inventory because it reduces inventory costs and offers a return on investment when the product is produced, rather than only on when sold.

2. A. What is CAE? Give an example? How does CAE increase the efficiency of the design process?

CAE is “Computer Assisted Engineering.”

An important CAE tool in mechanical and aeronautical engineering is finite element analysis that computes stress on physical objects. One of the many CAE tasks in designing an aircraft is determining the lift and drag characteristics of the wing. Hanley Innovations provides software to analyze model airplane airfoils on a PC. (Accurate the simulations compared to wind tunnel data). NASA's Virtual Windtunnel shows how visualization increases the power of a CAE tool.

CAE improves the efficiency of the design process because an engineer can test a design without having to build a model.
