Problem-solving Methodology for Engineering Design(cont-1) 3. Generation for alternative solutions /design concepts o Use of creativity, simulation o apply scientific principles, use qualitative reasoning o Need to generate high-quality alternative solutions 4. Evaluation of alternatives and decision making o Selecting the best among several concepts o Often under incomplete information o May consider simulations o Very important> checking including mathematical check, engineering-sense checks(intuition) o Consider all conditions/situations(e.g. humdity vibration, temperature.in selecting"optimal"solution 5. Communication of the results o Oral /written communication o Engineering drawings, 3D computer models, software, etcProblem-solving Methodology for Engineering Design (cont-1) 3.
