NO.221 You are the present ASQ Section Chairperson. Your supervisor, your company’s Director of Quality, is very proud of the company’s recent quality efforts which included ISO 9001 registration and the top quality award from the state.
He or she requested you to announce these achievements at the next ASQ Section meeting. As the ASQ Section Chair, your response should be which of the following?
Response:

NO.222 What is the failure rate of a system composed of three components, each of which can cause a system failure, and which have the following information?

Response:

NO.223 A high incidence of failures has developed during aircraft acceptance testing. The identified failure is that an instrument panel light has malfunctioned on 6 of the last 10 aircraft tested.
This problem needs to be investigated and a Failure Reporting and Corrective Action System (FRACAS) needs to be completed without stopping aircraft production.
If the cause of the failure is determined to be a faulty subassembly manufactured only by a single supplier, and this situation is threatening to shut down aircraft production, the next step should be to Response:

NO.224 If a test shows three failures in 50 hours of operation, how many failures will it show in 1000 hours of operation if the failure rate is constant?
Response:

NO.225 Which answer mathematically expresses the reliability of an active parallel system in which all component reliabilities are unequal?

Response:

NO.226 In a production reliability acceptance test (PRAT) plan, the design/discrimination ratio is expressed as the ratio of Response:

NO.227 It is often observed that unscheduled maintenance:

NO.228 The term “failure mode” is defined as the:
Response:

NO.229 For equipment consisting of three components connected in series whose respective reliabilities are
0.95, 0.94, 0.96, which could be used to calculate total probability?
Response:

NO.230 Which of the following considerations should a criticality analysis (CA) take into account?
I. Consequences of a failure.
II. Consequential damage of a failure.
III. Damage to the environment.
IV. Potential increase in efficiencies.
Response:

NO.231 Which test would potentially take longer than expected to complete?
I. Time terminated tests.
II. Failure terminated tests.
III. Sequential tests (PRST)
Response:

NO.232 The hazard function is:
I. The probability of failure during a very small time interval, assuming a failure occurs before that time.
II. A function of constant failure rate only.
III. A function of increasing failure rate only.
IV. The ratio of the probability density function to the reliability function.
Response:

NO.233 What are the life cycle costs for a new stamping machine purchased by a metal fabrication plant?
Pertinent cost data follows:
Purchase Price = $230,000
Repair Costs = $107,000
Post Purchase Costs = $870,000
Start Up Costs = $125,000
Maintenance Costs = $420,000
Energy Costs = $325,000
