A manager wants to assign tasks to workstations as efficiently as possible and achieve an hourlyoutput of four units. The department uses a working time of 56 minutes per hour. Assign the tasksshown in the accompanying precedence diagram (times are in minutes) to workstations using thefollowing rules:a. In order of most following tasks. Tiebreaker: greatest positional weight.b. In order of greatest positional weight. Tiebreaker: most following tasks.c. What is the efficiency?
(a) What is the cycle time necessary to achieve the desired rate of production?(b) Using the longest element rule, create workstations to balance the line,attempting to get as close as possible to the theoretical minimum numberof workstations.(c) What is the efficiency and idle time of the line balance?(d) The company considers that if the lamps are successful with the publicit may need to increase production to 30,000 units. The company thinksthe simplest solution is to obtain two more production lines, thus havingtriple capacity. Another option is to re-balance the line. Considering thata single worker is assigned to a work station, determine which option(more production lines or re-balancing) yields the smallest labour size.
Use the information in the table below (image 1):
a. Construct the Precedence Diagram.
b.The productive operating time is 55 minutes per hour for an 8-hour work. Compute the cycle time, CT, needed to obtain 50 units per hour.
OT=_____
D= ________
CT= ____________
c. Determine the minimum number of workstation, Nmin.
d. Assign tasks to workstations using the longest task-time Use the table format below. (IMAGE 2)
e. Compute the Percentage Idle Time.
f. Compute the Efficiency of the line.
g. Draw the Balanced Line.

- A Manager’s Woes Kyle Peschken has been a manager for the discount store Zelmart for the past two years. It’s time for his annual performance review, and Kyle would like to make a big impression on the corporate staff. Walking through the store, he makes a mental note of which departments need to be straightened, which ones need to be reorganized, and which employees he’d like to schedule during the week of his review. And then he sees it—blocking the aisles, creating commotion, and looking very unprofessional—the long line in the electronics department. It’s time to confront Chris, the sales clerk. “Chris, what’s the holdup here?” “I’mwaiting for a manager to approve this $120 check. And then I have to show this lady a digital camera from the display cabinet. She’s been waiting half an hour, and then . . . .” “Alright Chris . . .
