$1\mathrm{.}1$ Explain the human factors considered in logistics engineering design.

$1\mathrm{.}2$ Discuss the concept of Design for product $x$ and its implementation or application in the development of effective logistics engineering.

$1\mathrm{.}3$ More recently, there has been much emphasis on the application of computer$-$aided design $($CAD$),$ computer$-$aided manufacturing $($CAM$),$ computer$-$aided support $($CAS$)$ and the integration of these technologies to provide a smooth flow of information from the design to production. With the aid of a diagram, showcase the major activities and interfaces of CAD, CAM and CAS for optimal flow of information from product concept development and design, testing of a prototype, manufacturing and packaging of the finished product.

$1\mathrm{.}4$ Distinguish between failure mode, effects, and criticality analysis $($FMECA$)$ and fault tree analysis $($FTA$)$ in reference to system failure investigation.
