Another system composes of four items and each one of these items has constant failure rate of 0.0008 failures per hour. These items when they work the system will work. However, when any one of the system's items fails, the whole system will come to a complete halt. Calculate the following:
1. The reliability of the system at 2000 hour running time?
2. The system hazard rate?
3. Mean time to failure of the system?

A system composes of three components. These components have constant failure rates of 0.0004, 0.0005, 0.0003 failures per hour. The system will stop working, if any one of its components fails. Calculate the following: 1. The reliability of the system at 2500 hour running time? 2. The system hazard rate? 3. Mean time to failure of the system?

8.With one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the entire batch is accepted if every item in the sample is okay. A company has just manufactured 1591 CDs, and 196 are defective. If 3 of these CDs are randomly selected fortesting, what is the probability that the entire batch will be accepted? Does this outcome suggest that the entire batch consists of good CDs? Why or why not? If...

Answer the question: "what is a system?" It can be as short as one page or as long as 3 pages. What is a System? The term “system” originates from the Greek term syst¯ema, which means to “place together.” Multiple business and engineering domains have definitions of a system. This text defines a system as: System An integrated set of interoperable elements, each with explicitly specified and bounded capabilities, working synergistically to perform value-added processing to enable a User to...
