- Consider a production line with five stations in serial. The stations have the following process times in minutes (or minutes/unit). Station 1's process time is 9 minutes/unit. Station 2's process time is 10 minutes/unit. Station three has two identical machines, each of which process a unit in 12 minutes (each unit only needs to be processed on one of the two machines). Station 4's process time is 5 minutes/unit. Station 5's process time is 8 minutes/unit. Which station is the bottleneck station? a) Station 3 b) None of the other options c) Station 2 d) Station 5Consider the following two production processes making an electronic component for a navigation system. Both processes consist of 20 stations and operate at a cycletime of 1 minute/unit. Their most error-prone operation is step 9:• Process 1 has a final inspection at the end of the process and has about 300 units of inventory between step 9 and the inspection.• Process 2 has each worker check the work of the previous steps and about 50 units ofinventory between step 9 and the end of the process, roughly equally distributed across theremainder of the process.What would be the information turnaround time for a defect made at station 9?A production process is shown in the figure above. The drilling operation occurs separately from, and simultaneously with the sawing and sanding operations. Welding starts when both drilling and sanding operations have been completed. After welding, a product needs to go through only one of the three assembly operations (the operations are in parallel, where parallel lines perform the exact same operation). Considering the process times, specify the bottleneck(s). Sawing Sanding Drilling Welding Assembly You can choose more than one.

These tasks are assigned to 6 workstations (each workstation handling several tasks) in an assembly line set up. All workstations work the same amount of time (= cycle time), and move the (partial) product to the next workstation, and repeat this process. The last workstation generates the finished product. We need 1200 units made every day (= 8 hours). If we run this line with a cycle time of 0.3 minutes, what is the most amount of work (in minutes) that can be done on this product? (Give the answer with one decimal place)

Round answer to one decimal place.I Love Lucy: A Colorized Celebration - "Job Switching" clip https://youtu.be/K3axU2b0dDk Watch this short "I Love Lucy" clip. In it, you will see Lucy and her friend Ethel wrapping candies on an automatic assembly line. Their job is to make sure that each candy is wrapped. You will laugh when you see what happens as the speed increases on the line. Think about this clip from the point of view of operations management. This clip is much more than poor management techniques. So - what went wrong? What would you do to improve the process? Answer these questions with concepts from this week's readings.. Aquatica makes underwater camera housings for divers. The process begins with a solid rectangular block of aluminum that is used to make a single housing. A computer numerically controlled (CNC) machine drills into the block to make the metal “frame” of the housing. Each block requires 15 minutes of drilling. The frame is then chemically treated in a series of baths. There is ample capacity in the treating stage. Finally, a worker must manually attach the various buttons and components to the metal housing. This assembly takes 120 minutes per housing per worker and Aquatica has 6 workers trained to do this task. The CNC machine requires a 30-minute setup time before the production of a batch can begin. a. If the CNC machine produces 14 housings between setups, what would be its capacity (in housings per hour)? b. Assuming the process is supply-constrained, what is the utilization (as a number between 0 and 1) of the CNC machine if it operates in batches of 14 housings? c. Assuming…
