A carpenter produces 2370 per year in a three-step process. Step A Step B Step C Step A: Cutting the wood; reliability 0.87 Step B: Assembling tables; reliability 0.91 Step C: Painting the table; reliability 0.95 Each defective ('bad') table I produce costs me 22 KWD to rebuild. Buying a back-up saw for step A costs 550. 1. What is the overall reliability of this system that produces tables? Write your answer in decimal form with 3 decimals. 1. What is the overall reliability of this system that produces tables? Write your answer in decimal form with 3 decimals. is the system's reliability 2. Out of the 2370 tables we want to produce, how many defects (broken tables) will this process produce? Round up to get a whole number defective tables 3. If the cost per defective unit is 22 KWD, what is the annual cost of defects to the company at this time? KWD 4. The company wants to buy 1 extra back-up blades for Step A (so I now have 1 plus the original blade I had). Calculate the reliability of Step A with back-up. Then calculate the new reliability of the entire process. is the new systems reliability, after accounting for the back-up. 5. With the back up in place, how many total defects will you have now and what will that cost you (same as what you did for question 3 but with the improved system reliability)? KWD is the new total cost of defects 6. Calculate how much you saved by avoiding defects (compare answers of question 3 and 5). Also we should consider the cost of tue back-up saw costs us: 550 per extra unit. What is your total savings after also considering the cost of the backups? KWD is the total that can be saved by buying the backup saws
