ISYE 6501 SP19 HW09 Question 12.1 Describe a situation or problem from your job, everyday life, current events, etc., for which a design of experiments approach would be appropriate. Answer 12.1 ... One example design of experiments is to improve car design for aerodynamic efficiency. The possible factors that impact of the car design includes car height at the front, car height at the back, size of radiator grille, car rear spoiler height and size, etc. Since there are many combinations of these factors, a design of experiments approach could help car designers to collect data to make better car design decision. Question 12.2 To determine the value of 10 different yes/no features to the market value of a house (large yard, solar roof, etc.), a real estate agent plans to survey 50 potential buyers, showing a fictitious house with different combinations of features. To reduce the survey size, the agent wants to show just 16 fictitious houses. Use R’s FrF2 function (in the FrF2 package) to find a fractional factorial design for this experiment: what set of features should each of the 16 fictitious houses have? Note: the output of FrF2 is “1” (include) or “-1” (don’t include) for each feature [Show More]
