2. Plant A changed the design of an assembly line. The business manager would like to know how this new assembly line design performs. So the production rates of the past 100 days were collected. And a model of the assembly line is built in Arena software. The production rate needs to be specified as an input variable to run simulations. Please briefly describe how to specify the production rate in the simulation model. (Hint: briefly describe the input analysis process, which starts from collecting historical data) ( 25 points) 3. Below are 5 interarrival times that Ken recorded from a real system: 0.4,0.5,0.7,0.2,0.3. Unit is hour. Due to the lack of observed data, Ken wants to start with a Uniform distribution model, Uniform [0,1], to model the interarrival time variable. Please perform a goodness-of-fit test by using the Kolmogorov-Smirnov test with the level of significance =0.01 (the corresponding critical value is D0.01,5=0.669 ). To be specific, please write out the null hypothesis, conduct K-S test, and make you conclusion after the test. ( 25 points) 2. Plant A changed the design of an assembly line.
