Chap. 7 , question 1

1. 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 Problems 267 45 percent for assembly. Given the following schedule for the next six weeks, calculate the labor hours needed in each of the two work centers: 2. Returning to problem 1, what are the average labor-hours needed over the six-week period, and how might the company handle deviations from the average? How might they staff their departments? 3. Returning again to problem 1, the leather requires incoming inspection for each car seat in order to be sure the colors match. The time required for this is five minutes per seat. What are the expected capacity requirements for the inspection department over the next six weeks? Is there any way that this problem can usefully be combined with problem 1 ? 4. Returning to problem 3, what if inspection is done by the seat manufacturer in combination with assembly? How does this influence analysis of problem 1
