Introduction (1) -
Explain course administrative policies, e.g. development
and evaluation activities, homework guidelines, etc. -
Discuss place of ES201 in SEC. -
Discuss engineering vs. science, engineering
science vs. science; engineering analysis vs. engineering design. -
Discuss Systems, Accounting, and Modeling
Process. Demonstrate how it's natural to construct a model: select a
system, count something (accounting principle), and make modeling
assumptions. Illustrate usefulness of symbolic solution. |
