In a manufacturing company, the routing of part A is started from machine X, and continued by machine Y, and then machine Z, and 23,000 parts must be produced per month. The routing of part B is machine Y, Z, and X, respectively, and 31,000 parts must be produced per month. Set up time for machine X, Y, and Z are 35, 55, and 45 minutes, respectively. If the company works 6 days a week, four weeks a month, 10 hours a day, with 45 minutes lunch break and two breaks of 20 minutes, and given the following information. How much is the available processing time for Machine X (to process both parts A and B in total)? Machine X Machine Y Machine Z Standard time 7 min 3 min 9 min Part A Scrap estimate 3% 2% 2.5% Standard time 5 min 8 min 6 min Part B Scrap estimate 2% 4% 3% Historical Efficiency 92% 96% 89% Reliability factor 87% 91% 88%
