Exam 10: Operations Planning and Scheduling

Table 10.1 Bart Incorporated manufactures rotary air fans and uses a production-planning horizon of one-half year. It allows for regular time, part time, overtime, and subcontracting production to meet the demand but no more than 12 units may be made by each of these methods. Both anticipation inventory and backorders are allowed. The beginning (or current) inventory is 20 units. Their first attempt at a sales and operations plan has resulted in the following. -Use the information in Table 10.1. If anticipation inventory were 30 units at the start of the first month, what would the backorder cost be in the fourth month?

The Acme Company is a cosmetics manufacturing company with corporate offices in Indianapolis. Explain how corporate goals and objectives developed as a business plan in Indianapolis become the tangible plans and steps that are actually implemented in Acme's remote production plants located in Virginia, Ohio and Arizona.

The time that employees work that is longer than the regular workday or workweek for which they receive additional pay is:

Table 10.4 Gable Express Co. provides delivery service seven days a week. The daily requirements (in workers) are estimated as follows: Each worker is required to work five days per week, and each must have two consecutive days off. -Use the information in Table 10.4. What is the minimum number of workers required if preference is given to the pair S-SU in case of a tie in the selection of off days?

The university housekeeping and maintenance staff was cut by 50% during late December and early January when students were home breaking things and trashing their parents' houses instead of university property. This type of schedule for housekeeping and maintenance workers is a(n):

Which one of the following conditions favors a level strategy for manufacturing firms?

Choose any service and provide examples of how they can use a chase strategy for sales and operations planning.

Table 10.1 Bart Incorporated manufactures rotary air fans and uses a production-planning horizon of one-half year. It allows for regular time, part time, overtime, and subcontracting production to meet the demand but no more than 12 units may be made by each of these methods. Both anticipation inventory and backorders are allowed. The beginning (or current) inventory is 20 units. Their first attempt at a sales and operations plan has resulted in the following. -Use the information in Table 10.1. If the firm is committed to the regular production and overtime production as shown, what level of anticipation inventory would be needed at the start of the first month to result in an ending inventory of zero after month 6?

The planning horizon for a sales and operations plan is typically:

As October came to a close, Geoff updated the sales and operations plan with figures for actual sales, production, inventory, costs, and constraints before turning the production staff's attention to November, a process known as:

A retailer experiences a seasonal demand pattern for its services. Labor requirements over a typical six-month period follow. Costs associated with operations are as follows: Wages = $1,500 per worker per month Hiring cost = $1,500 per worker Layoff cost = $1,500 per worker The current workforce level is 11 workers. Use the spreadsheet approach and the preceding data to answer the following questions. a. What is the total cost of the staffing plan, including the cost of regular wages, hiring, and layoffs using a chase strategy with hiring and layoffs, but no overtime? b. What is the total cost of the staffing plan, using a level strategy in which no overtime is allowed, and the undertime paid for? c. Suppose that overtime is allowed up to 25% of the regular-time capacity, and that overtime wages are 150% of the regular-time rate. What is the total cost of the level strategy with overtime and undertime that also minimizes undertime?

A company is attempting to cope with seasonal demand patterns by managing its demand. Which one of the following will not help achieve this aim?

Table 10.3 A large distribution center uses some part-time employees in its workforce. Each part-time employee works a maximum of 80 hours per month. The workforce requirements (expressed as the number of part-time employees working the maximum regular time of 80 hours per month) are given in the following table for the next six periods. The relevant costs are: Wages = $350/month/worker Hiring cost = $100/worker Layoff cost = $50/worker Overtime cost = 150% of regular-time rate The current workforce level is 60, and overtime cannot exceed 25% of regular-time capacity. Use the spreadsheet approach to answer the following questions. -Use the information in Table 10.3. The total cost of the staffing plan, including the cost of regular wages, hiring, and layoffs, using a chase strategy with hiring and layoffs but no overtime, is:

Scheduling involves generating a work schedule for employees or sequences of jobs or customers at workstations.

The meaning of undertime is:

Anticipation inventory is used to absorb uneven rates of demand or supply.

Table 10.7 The framing department has six jobs waiting to be processed. It is now time zero and all jobs are ready to begin. Each has only one operation remaining. All jobs arrived at the same time, and FCFS begins with job A, then B, etc. -Using the information in Table 10.7 and the first-come, first-served (FCFS) rule, what is the average days past due?

Which one of the following statements concerning supply options is best?

Table 10.10 A work center has the following six jobs waiting to be processed (all times are shown in days): -Use the information in Table 10.10. What is the average past due (in days) using the EDD rule?

A service firm uses a level utilization production-planning horizon of six months. They have developed a forecast for the coming six months that appears in the table. They can add no more than 33% of their production capacity as overtime. What is the minimum cost sales and operations plan?
