Homework Answers
13. In human decision-making process there is back and forth interactions between short-term memory and long-term memory
14. An example of divided attention is when driving a car and talking on the cell phone.
15. A 95th percentile male who is about 73inch tall means that 95% of the male population are larger than him. False!
NOTE: If you are the 95Th percentile, 95% people are below you and 5% people are above you.

Assume that an engineering system can fail due to a maintenance
error caused by factors such as poor equipment design, inadequate
training, poor work environment, use of deficient maintenance
manuals, or inadequate work tools. Two major factors for poor
equipment design are oversight or “no formal consideration of the
occurrence of maintenance error”. The “no formal consideration to
the occurrence of maintenance error” factor can be caused by either
no requirement in design specifications or insufficient allocated
funds. Two important...

1. There are many definitions of engineering design. The Accreditation Board for Engineering and Technology (ABET) defines engineering design as: "Engineering design is the process of devising a system, component, or process to meet desired needs. It is a decision-making process (often iterative), in which the basic sciences, mathematics, and the engineering sciences are applied to convert resources optimally to meet these stated needs...". Identify three important words or phrase from the above definition and for each of them explain...

1. Why do you think that the ilities are considered a part of systems engineering rather than design? 2. Contrast the “traditional” ilities of reliability and maintainability with those of human factors and environmental engineering. In what ways are they similar? In what ways are they different? 3. Do the same disciplines apply to software and hardware? For example, does software “break” in the way that hardware does? Does it break without warning and unpredictably at all?
