Question

A manufacturing facility makes a product which consists of tasks A, , K and requires that these be completed in an order that obeys a set of precedence requirements. The following table gives the performance time in minutes/unit and the preceding task(s) for tasks A,..., K. Task Performance Time Precedin Task N/A N/A (minutes/unit) A, B D, E These tasks have been assigned to four workstations: Station 1 has tasks A and B; Station 2 has tasks C, D, and E; Station 3 has tasks F and H; and Station 4 has tasks G, I, J, and K. What is the efficiency of the line? (Specify the percentage as a two digit number after rounding. Do not include the percent sign.)

Explanation / Answer

The allotment of the tasks are done as follows:

Workstation No.

C, D, E

F, H

G, I, J, K

Total time at workstation

18

Thus, cycle time of the assembly line is 18 minutes (longest processing time for the workstation). The product will come out of line every 18 minutes.

Total work content or processing time for the product = 49 minutes

Efficiency = Total work content/(no. of workstation x cycle time) = 49 /(4 x 18) = 0.6805

Efficiency = 68.08%

Workstation No.
