b) Given the demand, what is the cycle time for this operation?
c) What is the theoretical minimum number of workstations?
d) Assign tasks to workstations.
e) How much total idle time a present each cycle?
f) What is the efficiency of the assembly line with five stations? With six stations?

To meet holiday demand, Alex's Pie Shop requires a production line that is capable of
producing 50 pecan pies per week, while operating only 40 hours per week. There are only
four steps required to produce a single pecan pie with respective processing times of 5
minutes, 5 minutes, 45 minutes, and 15 minutes.
a. What should be the line's cycle time?
b. What is the smallest number of workstations Alex could hope for in designing the
line considering this cycle time?
c. Suppose that Alex finds a solution that requires only four stations. What would be
the efficiency of this line?
The three-station work cell illustrated in the figure below has a product that must go through one of the two
machines at station 1 (they are parallel) before proceeding to station 2.

- Employees Layoffs at the University Medical Center The University Medical Center is medium-sized, 300-bed capacity hospital at Dasmarinas Cavites. The facilities have grown gradually over the years and are now the 2nd largest in the town of Dasmarinas. It is entirely nonunion and has never experienced an employee layoff since its inception. Sister Veronica Cornista, the Chief Executive Officer of the hospital for 8 years presented a rather bleak financial of the BOD. This according to her is the result of the declining occupancy rate which has affected the hospital’s revenues to such an extent that it ran a deficit for the first time last 1998. Such declines have not been unusual for this industry because of increasing competition. So far, the only response to these changes has been tightening of requirements for equipment or supply purchases. The projected deficit for the coming year is around 1,300,000 unless some additional revenues were identified or some additional savings…arrow_forwardSue Helms Appliances wants to establish an assem-bly line to manufacture its new product, the Micro Popcorn Popper.
