The Barberton Municipal Division of Road Maintenance is charged with road repair in the city of Barberton and the surrounding area. Cindy Kramer, road maintenance director, must submit a staffing plan for the next year based on a set
- Find a level staffing plan that relies just on overtime and tile minimum amount of undertime possible. Overtime can be used to its limits in any quarter. What is the total cost of the plan and how many under time hours does it call for?
- Use a chase strategy that varies the workforce level without using overtime or undertime. What is the total cost of this plan?
- Propose a plan of your own. Compare your plan with those in parts (a) and (b), and discuss its comparative merits.

Tax Prep Advisers, Inc., has forecasted the following staffingrequirements for tax preparation associates over the next12 months. 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. The plan may call for a one-timeadjustment of the workforce before month 1.b. Using a chase strategy, prepare a plan that is consistent withthe constraint on hiring and minimizes use of overtime.c.…

- XYZ Company produces and sells 2 products, Lambda and Gamma, and the production process goes through two departments. Traditionally Manufacturing Overhead (M/O) cost is applied on the basis of direct labor hours (DLH); estimated M/O cost is $ 5,757,500 and the estimated DLH is $12,250 for the most recent period.The team decided to replace traditional plantwide costing system to activity-based costing system. There are 3 activity cost pools which represent 3 activity areas at the plant. Direct Labor wage rate is $ 30 per hour. Compute total cost per unit (for lambda and gamma) using activity-based approach.

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

The total workforce comprises ten employees, out of which five are in sales, three are in operations, one is handling legal and accounts matters, and one manager is also the owner of the company. Total annual turnover is enough to run the company smoothly. Recently another director has joined who brought large investment to the company. The Board of directors has decided to expand the business in other cities and establish offices overseas in potential locations. This expansion policy will directly be linked to the new manpower needs. Therefore, the board has decided to open an HR department with one HR manager and three staff to look after HR operations. The new HR manager has noticed that the company has a very convenient way of recording the data, where all transactions are recorded on excel documents. “this may not work in the new setup with many branches around the world”, he mentioned in the BOD meeting.…arrow_forwardManufacturing Company uses FIFO method of accumulating costs in a two-department process.

- Fast Burger Inc. is building a new restaurant near a college football stadium. The restaurant will be open 16 hours per day, 360 days per year. Managers have concluded that the restaurant should have the capacity to handle a peak hour demand of 120 customers. Assume front-counter service personnel can take and assemble orders at the service rate of 14 customers per hour and the target labor utilization rate for this job is 70 percent. According to the information, determine the the number of front-service counter people that should be assigned to this peak demand period.

Clearly state the decision rule you use and complete the below table using the selected rule. Decision Rule Logic Longest work element Picking the candidate with the longest time to complete is an effort to fit in the most difficult elements first, leaving the ones with short times to “fill out” the station.
