Question 2. Dr. Larsen is a faculty member at University of Helsinki. He plans to spend a one-week vacation in Paris and intends to fly on May 1st, 2021. The following list of available flights (Table 2) has been found via flight searching engine Expedia. 1) Based on the provided flight information, select four objectives that Dr. Larsen could consider when he selects the flight. For each of the objective, which flight(/s) is(/are) optimal? 2) Considering all the objectives you have selected in (1), identify the Pareto-optimal solutions for Dr. Larsen. 3) If it is still difficult for Dr. Larsen to select a single flight from the Pareto-optimal solutions, please help him construct a utility function to combine your four objective functions, say, fu, f2, f3, f4. Justify why the utility function is constructed in that way and then find the optimal flight accordingly. 1 3h 5m (Nonstop) 4:05pm - 6:10pm Helsinki (HEL) - Paris (CDG) $231 One way per traveler Finnair 3 cleaning and safety practices 2 1:55pm - 5:45 pm Helsinki (HEL) - Paris (CDG) 4h 50m (1 stop) 1h 5m in Amsterdam (AMS) $149 One way per traveler K KLM 3 cleaning and safety practices 3 $333 One way per traveler 5h 10m (1 stop) 1:30pm - 5:40pm 1h 20m in Frankfurt (FRA) Helsinki (HEL) - Paris (CDG) Lufthansa Lufthansa 1040 operated by Lufthansa Cityline 4 cleaning and safety practices 4 $149 One way per traveler 1:55pm - 8:00pm 7h 5m (1 stop) 3h 15m in Amsterdam (AMS) Helsinki (HEL) - Paris (CDG) KLM KLM KLM 2017 operated by Air France 3 cleaning and safety practices 7:00am - 7:30pm 13h 30m (2 stops) 4h 10m in Frankfurt (FRA) 3h 10m in Vienna (VIE) Helsinki (HEL) - Paris (CDG) Austrian Airlines Austrian Airlines 7440 operated by Lufthansa 4 cleaning and safety practices 5 $389 One way per traveler 6 9h 50m (1 stop) 5h 55m in Amsterdam (AMS) $180 One way per traveler 7:00am - 3:50pm Helsinki (HEL) - Paris (CDG) Multiple airlines 3 cleaning and safety practices
