INSE 6270 Quality-based System Engineering
Assignment 1
Answers
Question 1:
Part a)
Design A
R (reangularity) = sqrt(1-(3*5+2*4)^2/(3^2+2^2)(5^2+4^2)=0.0866
S (semangularity) = 3/sqrt(3^2+2^2)*4/sqrt(5^2+4^2)= 0.519
Design B
R (reangularity) = sqrt(1-45^2

First Axiom:
The Independence Axiom
The Independence of FRs must always
be maintained.
Second Axiom:
The Information Axiom
The design that has the smallest
information contents is the best.

Assumptions
Only two FRs and DPs (or less)
Probability density distribution is uniform
Key concept
How the variations of DPs (DP) affects the
variations of FRs (FR)
The probability is defined the variations of FRs
(FR) over the design range (FR)
