The training I have had on

the Solver was adequate.

Additional training about

the Solver would be

helpful.

Additional experience with

the Solver would be

helpful.

The Solver displays only necessary

information for my role as a planner.

The outputs/results of the Solver are

not displayed effectively.

Challenges with the Solver? (Open Comments)

“Being able to explain why the solver gave certain results vs. the expected results”

“lack of training”

“Updated training materials”

“some reports show massive amount of data that is not relevant”

“GUI is hard to read”

“Lack of Excel functionality for input reports (copy/paste)”

Page 8: Communicating Optimization Resultsctl.mit.edu/sites/ctl.mit.edu/files/library/public... · Research Objectives Communication methods Visualization approaches New areas for improvement

The understanding of, support for, and communication around the Solver is very high; Current processes should stay in effect with only minor changes. Initial and version-update user training should be robust and application-oriented

Data Visualization

…not just a software tool

“clutter & confusion are not attributes of information, they are failures of design”

The understanding of, support for, and communication around the Solver was better than expected.

Initial and version-update user training should be robust and application-oriented.

Innovative data visualization techniques may help increase understanding and lead to better communication.
