An airline company wishes to reduce the customer waiting time at the gates at a major airport using Taguchi Design of Experiments. The management decides to use Taguchi design of experiments for this project.

Control Factors	Level 1	Level 2
Assigned seating	Yes (Y)	No (N)
Number of check-in bags allowed	1	2
Food and beverage supply on flight	Beverage only (B)	Food and Beverage (FB)

Since there are 3 control factors with 2 levels in each, a total of 8 “runs” are possible. However, since performing the experiment with all possible runs is time-consuming, the management decides to consider only 4 runs.

The noise factors are four different gates assigned to the airline. The experiment data is shown in the following table:

Assigned	Bags	Food/Bev	Gate 1	Gate 2	Gate 3	Gate 4
Y	1	B	31	27	29	32
Y	2	FB	46	40	38	35
N	1	FB	31	29	28	37
N	2	B	45	43	42	41

Make recommendations to the airline company, using Taguchi analysis.
