please let me know how to get this answers.
The Pullman Mfg., Inc three-station work ccll illustrated in the figure below has two machines 13. at station I in parallel. (The product needs to go through only one of the two machines before proceeding to station 2.) The manager. Ms. Hartley, has asked you to evaluate the system if she adds a parallel machine at station 3. a) The throughput time of the new work ccll is 27 minutes (enter your response as a whole number). b) The bottleneck time of the new work ccll is 6 minutes per unit (enter your response as a whole number). c) If the firm operates 9 hours per day, 6 days per week, the weekly capacity of the work ccll with the second machine at workstation 3 is 540 units (enter your response as a whole number). d) If the firm operates 9 hours per day. 6 days per week, the weekly capacity of the work cell without the sccond machine at workstation 3 is 324 units (enter your response as a whole number).Explanation / Answer
a) Throughput time is the amount of time required for a product to pass through a manufacturing process.
So, throughput time = 12 + 5 + 10 = 27 minutes.
b) Production per hour of station 1 = (60 min / 12 min) x 2 = 10 units per hour.
Production per hour of station 2 = (60 min / 5 min) = 12 units per hour.
Production per hour of station 3 = (60 min / 10 min) = 6 units per hour.
So, clearly, the bottleneck department is station 3 as it is producing least number of units per hour and the bottleneck time is 6 minutes.
c) Total available time per week = 9 hr x 6 days x 60 min = 3,240 minutes.
Production with one machine at station 3 = 3,240 / 10 = 324 units.
Production with two machines at station 3 = 324 x 2 = 648 units.
d)
Total available time per week = 9 hr x 6 days x 60 min = 3,240 minutes.
Production with one machine at station 3 = 3,240 / 10 = 324 units.
