Question

Why do we use optimization after initial layout?

(a) To provide lowest cost structure

(b) To improve highest cost structure

(c) To reduce effectivity

(d) To lower efficiency

This question was addressed to me during an interview for a job.

This interesting question is from Conceptual Design Process topic in division Design Process Overview of Aircraft Design

Answer 1

Correct option is (a) To provide lowest cost structure

For explanation I would say: Optimization techniques are used to provide the lightest and most cost effective structure. In other words, it is used to check whether my design is best for given requirements, for given cost constraints.
