Use the fоllоwing infоrmаtion to аnswer Questions 24-30. The mаnager of Wash Me car-wash center has built a simulation model to simulate and analyze the center’s service processes. Based on 10 simulation runs, the manager calculates that the average cycle time has a sample mean of 30 min and a standard deviation of 10 min. Please answer the following questions. Answer Questions 26-28 also considering the following information In order to reduce Wash-Me’s average cycle time, an improved system has been proposed and simulated. After 10 simulation runs, the new system’s average cycle time has a sample mean of 25 min and a standard deviation of 12 min. The manager would like to conduct a proper hypothesis test to see if the new system is better than the old system at 10% significance level. Suppose that the manager runs 9 more simulations for both the old and new system and then use Excel to perform a t-test with 5% significance level. What conclusion can you draw from Excel output (see below; also available from ttest.pdf)?
Use the fоllоwing infоrmаtion to аnswer Questions 2-19. Suppose you аre leading a team to help H&R Block (a tax preparation company) improve its tax preparation service process. After several field trips to the company, you decided that tax preparation process consists of two activities: (i) preparing necessary documents (DocPrep, hereafter) performed by a team led by Ted, followed by (ii) completing tax return forms (FormPrep, hereafter) performed by a team led by Mary. You built the following model in ExtendSim to simulate this process (also available from Flow chart base model.pdf in case the picture does not show up). Answer Questions 15-19 also considering the following information You showed the updated simulation model to the manager and he is very excited about its potential in assisting business decision-making. Specifically, many clients are complaining of having to repeat the same message to two separate teams (i.e., Ted’s team that performs DocPrep and Mary’s team that performs FormPrep). To address it, the manager is contemplating to offer cross-training so that each team can perform both activities. Although the manager is optimistic about the benefit of cross-training in improving customer satisfaction, he is unsure if this will adversely influence the total throughput and the time each client has to wait to get back from the company. To help the manager evaluate the impact of cross-training on process performance, you have revised the simulation model (see below; also available from Model 4.pdf) such that each team can perform both activities. In Resource Pool, you should specify all the followings EXCEPT:
