1. A work center consists of 4 machines each working a 16 – hour day for 5 days per week. What is the weekly available time?

Total weekly available time in hours = 4 (machine) * 16 (hour) * 5 (days) = 320 hours.

2. Over a period of 4 weeks, a work center produced 50, 45, 40, and 55 standard hours of work. What is the demonstrated capacity of the work center?

Measured capacity=Total of standard hours/Total weeks

50 hours+45 hours40 hours+55 hours/ 4

=190 hours/4= 47.5 standard hours per week

Demonstrated capacity for a work station is 47.5 standard hours per week

3. An order for 100 of product is processed on work centers A and B. The setup time on A is 50 minutes, and run time is 5 minutes per piece. The setup time on B is 60 minutes, and the run time is 5 minutes per piece. Wait time between the two operations is 5 hours. The move time between A and B is 40 minutes. The wait time after operation B is 5 hours and the move time into stores is 3 hours. Queue at work center A is 25 hours and B is 35 hours. Calculate the total manufacturing lead-time for the order.

Required capacity for work station A (50 mins + (100 x 5 mins) 550 minutes

Queue tie for A

Wait time for work station A 1,500 mins

300 mins

Move time from A to B 40 mins

Required capacity for work station B (60 mins +(100 x 5 mins) 560 mins

Queue time for B

Wait time after operation B 2, 100 mins

300 mins

Move time to store 180 mins

Total manufacturing lead time 5,530 mins

mins---> hours 92 hours, 10 mins

Total manufacturing lead time is 92 hours, 10 mins
