- . 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…Panini, a popular sandwich shop, offers 3 types of sandwiches: grilled vegetables, grilled chicken, and pastrami. Demand (sandwiches per hour) are Grilled Vegetables = 25, Grilled Chicken = 15, and Pastrami = 10. There are up to five steps in the process of making sandwiches, listed below with processing times. Step Grilled Vegetables Grilled Chicken Pastrami 0.75 minutes 0.75 minutes 0.75 minutes 0.75 minutes 1.4 minutes 1.4 minutes - - - - 3 minutes 3 minutes 2 minutes 2 minutes 2 minutes 2 minutes 0.5 minutes 0.5 minutes 0.5 minutes 0.5 minutes Only 50 percent of customers want their sandwich toasted, no matter which sandwich is ordered. Suppose Panini employs 1 worker at each step. Instructions: Round all answers to 1 decimal place. What is the implied utilization of each of the five steps in this process? Cut ____% Grill ____% Slice ____% Toast…Consider 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 process of making chair is described as follows: Stage 1 Seat and back attached Stage 2 Legs attached The production speeds are 15 chairs per hour for Stage 1 and 30 chairs per hour for stage 2. The cycle time of the process is ______minutes. The flow time of the process is ______ minutes.These four phases make up a machine cycle, which is also known as a process loop. What percentage of a machine's cycle time do you value the most? Should I be concerned about replacing parts of the machine cycle when they wear out? Is the problem of switching modules improved by adding a second module?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 5
- Formtech Inc. produces transformers. Each order is custom designed and manufactured for the customer. Each order goes through 3 phases: Transformer Design, which takes 4 weeks. Procurement, which has a lead time of 8 weeks. Assembly and Testing, which takes 4 weeks The design group can handle only 4 projects at any given time. The other groups are not capacity constrained. How much total work-in-process (number of projects started but not yet completed) does the company typically have? (Hint: Little's Law)Consider a balanced line consisting of five single-machine stations with exponential process times. Suppose the utilization is 75 percent and the line runs under the CONWlP protocol (i.e., a new job is started each time a job is completed). a. What is the WlP level in the line? b. What is the cycle time as a percentage of To? c. What happens to WIP, CT, and TH relative to the original system if you make each of the following changes (one at a time)? i. Increase the WIP level ii. Decrease the variability of one station iii. Decrease the capacity at one station iv. Increase the capacity of all stationsH4. A manufacturing process consists of three processes. Step 1 requires 4 minutes per unit, step 2 requires 6 minutes per unit, and step 3 requires 7 minutes per unit. 20% of units that complete the third step require rework, which means those units must start the process over at step 2 (processing times are the same for units being reworked) and rework is always successful. Demand at the shop is 0.4 units per minute. What is the capacity of the shop (in units per minute)?
