Assume that an assembly line produces three products, A, B, and C (see Figure 42-A). The available operating time per shift is 480 minutes. The cell operates two shifts per day. The average daily demand is 160 of A, 120 of B, 200 of C. What is the takt time?
The assembly cell has the following design: M designates a single-cycle automatic machine H designates a manual operation
Assume the walk time between all stations is three seconds.
a. The cell has a yield of 97%. What is the necessary cell cycle time?
b. Develop the standardized work combination time graph for one required cycle time period for each operator as shown.
c. Can the takt time be met? If not, then why not?
d. What would you try to fix/improve before adding workers?
e. How would you facilitate this improvement?
f. Assume certain improvements and provide a workable cell design.
