A rm makes car seats for an automaker in two varieties: leather and fabric. The standard labor-hours
Question:
A firm makes car seats for an automaker in two varieties: leather and fabric. The standard labor-hours for these are 1.2 and 1.0 hours, respectively. The seats are made in two work centers, sewing and assembly, where the average percentage of work has been 55 percent for sewing and 45 percent for assembly. The following schedule for the next six weeks is given.
Week | 1 | 2 | 3 | 4 | 5 | 6 |
Leather | 15 | 20 | 18 | 21 | 15 | 13 |
Fabric | 65 | 60 | 62 | 59 | 65 | 67 |
a) Using the CPOF (Capacity Planning Using Overall Factors) approach, calculate the labor-hours needed in each of the two work centers in each week.
b) Suppose the following information is given. Using the capacity bills approach, calculate the labor-hours needed in each of the two work centers in each week.
Work Center | Time (hours/unit) | |
Leather | Fabric | |
Sewing | 0.7 | 0.6 |
Assembly | 0.5 | 0.4 |
Total | 1.2 | 1.0 |
