Team Vision for System-Level Design Phase

This phase included breaking down the people mover's objective into many functions in order to determine the general areas that need concepts generated. Concepts were then developed and compared against each other to determine which one was the best. Lastly, bench marking and engineering analyses were constructed to determine if the solutions were feasible.

The team accomplishments can be seen below and in the Systems Design Presentation.

Morphological Chart and Concept Selection

The team took top level functions from the functional decomposition and generated different concepts for each of the functions. This can be seen in the morphological chart below:
