A production line is to be designed to assemble a product. The assembly of this product requires three tasks, one of which requires 0.3 minutes to complete, one of which requires 1.4 minutes to complete , and one of which requires 0.7 minutes to complete. If this production line has three workstations and a cycle time of 1.5 minutes , what is its efficiency ?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…
- Manufacturing Company uses FIFO method of accumulating costs in a two-department process. Materials are introduced at the inception of the process except for a special material which is added in department 2 at 60% completion as to overhead.
