Chapter 4, Problem 7P
Macon Controls produces three different types of control units used to protect industrial equipment from overheating. Each of these Linus must be processed by a machine that Macon considers to be their process bottle neck. The plant operates on two 8-hour shifts, 5 days per week, 52 weeks per year. Table 4.2 provides the time standards at the bottleneck, lot sizes, and demand
- How many machines are required to meet minimum (pessimistic) demand, expected demand, and maximum (optimistic) demand?
- How many machines are required if the operations manager decides to double lot sizes?
- If the operations manager has three machines and believes that the plant can reduce setup time by 20 percent through process improvement initiatives, does that plant have adequate capacity to meet all demand scenarios without increasing lot sizes?

Scenario
The KOREAN factory of Hi-Tech Metal, Inc. primarily manufactures plumbing system parts for gas pipes, drainage pipes, water supply pipes and hoses etc. A mainframe computer was used for scheduling, but it took a lot of time and unnecessarily put heavy workload on scheduling managers and on-site workers. Following are the associated problems to meet customers’ needs
Lengthy 3 to 4 days schedule drafting time, caused by mainframe computer’s long processing time.
Inflexibility of mainframe computer to sudden order changes, leading to tedious manual calculation and direct on-site adjustment
Extra workload for on-site workers
One-month base scheduling that cannot meet customers’ need,
Task 3
Considering above scenario identify the manufacturing system for the components
[Based on the stakeholder, strategic goals , explain the manufacturing system]

- Southeastern Oklahoma State University's business program has the facilities and faculty to handle an enrollment of 2,200 new students per semester. However, in an effort to limit class sizes to a "reasonable" level (under 200, generally), Southeastern's dean, Holly Lutze, placed a ceiling on enrollment of 1,500 new students. Although there was ample demand for business courses last semester, conflicting schedules allowed only 1,400 new students to take business courses. What is the utilization rate for Southeastern?

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_forward

Management would like three alternative staffingplans to be developed. The company currently has 10 associates. No more than 10new hires can be accommodated in any month because oflimited training facilities. No backorders are allowed, andovertime cannot exceed 25 percent of regular-time capacityon any month. There is no cost for unused overtime capac-ity. Regular-time wages are $1,500 per month, and overtimewages are 150 percent of regular-time wages. Undertime ispaid at the same rate as regular time. The hiring cost is $2,500per person, and the layoff cost is $2.000 per person.a. Prepare a staffing plan utilizing a level workforce strategy,minimizing undertime.
