The global wind power industry includes operations in very random
environments, both natural and artificial. Therefor
1. List important uses of failure data.
1 conceptual design
2 preliminary design,
3 test planning
4 design reviews
6 quality assurance and inspection planning
7 logistic support planning inventory management
2. List at least five of the most important common reasons for product failures.
1 Wrong usage by the consumer
2 Incorrect manufacturing
3 Faulty reasoning
4 Poor understanding of the problem to be solved
5 Unsatisfactory data collection
6 Incorrect stora
2. Discuss the need for reliability in product design.
There have been many factors responsible for the consideration of reliability in
product design including
1 product complexitythe increase in the product complexity with respect to parts
1. Prove using the decomposition method, that a five unit bridge networks
reliability, Rb, is given by:
Rb 2R 2 2R 3 5R 4 2R 5
where R is the unit reliability.
This occurs when C is ALWAYS
RELIABLE. Here, C beco
