Given the following, what are the machine fractions for machines A, B, and C to produce parts X and Y?

Machine A Machine B Machine C Part X standard time 0.15 hr 0.25 hr 0.1 hr Part Y standard time 0.10 hr 0.10 hr 0.15 hr Part X defect estimate 5% 4% 3%

Part Y defect estimate 5% 4% 3%

Historical efficiency 85% 90% 95%

Reliability factor 95% 90% 85%

Equipment availability 1600 hr/yr 1600 hr/yr 1600 hr/yr Part X routing is machine A, then B, and then C; 100,000 parts are to be produced per year. Part Y routing is machine B, then A, and then C; 200,000 parts are to be produced per year. Setup times for parts X and Y are 20 minutes and 40 minutes, respectively.
