Littlefield Labs has three stations to process blood testing jobs. Fill out the following table on your scratch paper if needed. Note that additional machines have been installed and the bottleneck may have been shifted to a different place. Station Mean Raw Processing Time Number of Capacity (jobs per Bottleneck? (Yes Parallel Machines day) or No) Installed #1 5 hours #2 1.5+0.5 - 2 hours 2 #3 1.83 hours 2 What is the whole factory's capacity (a.k.a. bottleneck rate) in "jobs per day" now? O 12 jobs per day 25.26 jobs per day 4.8 jobs per day 19.2 jobs per day 24 jobs per day Littlefield Labs has three stations to process blood testing jobs. Fill out the following table on your scratch paper if needed. Note that additional machines have been installed and the bottleneck may have been shifted to a different place. Station Mean Raw Processing Time Number of Capacity (jobs per Bottleneck? (Yes Parallel Machines day) or No) Installed #1 5 hours 4 #2 1.5+0.5 = 2 hours #3 1.83 hours 2 If demand rate is 9.6 jobs per day, what is the capacity utilization at the bottleneck? 38% 40% 100% 50% Littlefield Labs processes blood tesing jobs and its first Station takes care of Sample Preparation (Step 1). It takes, on average, 5 hours to prepare a sample as the raw processing time. Station 1 currently has a capacity utilization of 50%. Assume the variability factor V = 1 for moderate variability from both the demand side and the process side. What is the expected Waiting Time for jobs to stay in the queue in front of Station 1? O 5 hours O 2.5 hours O 10 hours 0 7.5 hours
