In 1 – 3 paragraphs for each question, answer the questions.

Control Concepts and Methods

Question 1: Provide 1 example of an open-loop system and 1 example of a closed-loop system.
Question 2: Given an unstable pattern of variation, describe the relationship of control limits, Type 1 errors, and Type 2 errors.
Question 3: Given the following: n = 10 samples, = 0.30 inches and the process range of = 0.0025 inches. What are the control limits of the -chart and – chart?

Design for Reliability

Question 1: From a design perspective, define reliability, and describe its major characteristics.
Question 2: A system consists of four subsystems connected in series. Determine the overall system reliability. Each subsystem has the following reliabilities:

Subsystem A= 0.95
Subsystem B = 0.80
Subsystem C = 0.85
Subsystem D = 0.90

Question 3: Assume that a system has operational redundancy with three subsystems connected in parallel. Determine the overall system reliability. Each subsystem has the following reliabilities:

Subsystem A = 0.95
Subsystem B = 0.80
Subsystem C = 0.90

Question 4: A system has five subsystems with the following Mean-Time Between Failures (MTBF). The five systems are connected in series. Determine the probability of survival for an operating period of 500 hours:

MTBF of Subsystem A= 5,270 hours
MTBF of Subsystem B = 8,110 hours
MTBF of Subsystem C = 4,750 hours
MTBF of Subsystem D = 6,050 hours
MTBF of Subsystem E = 1,800 hours

Your response should address each of the major points of each question as well as the following:

For paragraph answer questions, each response should be 1 – 3 paragraphs of original information.
For paragraph answer questions, each response should include at least 1 reference, and all sources should be cited.
Grammar, spelling, punctuation, and format should be correct and professional.

For the questions that include problem solutions, use the following guidelines for your answers:

The final solution should be correct.
The analytical process for solving the problem should be neatly laid out, and it should be logically defined.
