- . 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…O 1000 workers are currently working in Sigma Manufacturing Industry. This industry is paying the wages to its workers on a daily basis. No vacation is given for any occasion in this industry. The factory is running from 8:30 am to 5:30 pm with a lunch break of 60 minutes. This break is not counted as working hours. Last year, 10 accidents occurred which caused almost 50 injuries. Around 50 people remain absent everyday in this industry. Gama Production Factory was a sister concern of Sigma Manufacturing Industry which is closed now. It had half of the workers of Sigma. In 2017, 50 accidents occurred and each accident caused 3 injuries and a loss of 8 hours each on an average. Working hours and attendance rate were the same as Sigma Manufacturing Industry. Now compute the frequency rate and severity rate for Gama Production Factory. Also, illustrate the kinds of key accident data you should collect from the place where an accident has occurred.what does the ENABLE component of SCOR model cover and why is it not sequential like other parts of the model? give examples
