Error Prevention and Troubleshooting
ثبت نشده
چکیده
This chapter summarizes the common errors haunting the beginner modelers. Modeling is a tricky, error-inviting business, as you would probably agree through doing the homework problems. The errors can be as small as a typo, or as big as capturing the relationships between quantities incorrectly (i.e. making a wrong flowchart to start with). Some errors are easily detected and reported by Berkeley Madonna through an error message, e.g. divide by zero; but many others are not obvious to locate. The worst case is an error that does not cause any apparent trouble. No error messages, no quantities blowing up. Yet the deceptive results lead us to totally incorrect conclusions.
