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.Which one of these trade-offs works to your greatest advantage in terms of reducing costs over the entire planning period?

A customer is given a due date for their product order with:

Table 10.8 Suppose that the following eight jobs must be scheduled through a car repair facility (repair times are shown in days): -Use the information in Table 10.8 to answer this question.What car is repaired the latest (the most past due)if an SPT sequence is obeyed?

The sales and operations planning strategy to be used should be consistent with the business environment.Which one of the following pairs of business environment and strategy is consistent?

The spreadsheet approach to sales and operations planning for a services provider includes inventory costs as one factor to be considered.

Which of the these sales and operations planning levers is associated with interviews,training,and severance pay?

Use the information in the preceding table and sequence the seven jobs using first come,first served (FCFS)and earliest due date (EDD).Calculate the average flow time and average past due.It is now time eight.

Which of the following is the best example of a physical constraint on the sales and operations plan?

Operations planning and scheduling is the process of making sure demand and supply plans are in balance.

Table 10.2 Archie Toys is a retailer operating out of Wichita,Kansas.It experiences a seasonal demand pattern for its services.Labor requirements over a typical six-month period follow.The workforce requirements (expressed as number of employees)are given in the following table for the next six periods. Costs associated with operations are as follows: Wages = $800 per worker per month Hiring cost = $300 per worker Layoff cost = $200 per worker The current workforce level is nine workers,and the undertime is paid for.Use the spreadsheet approach and the preceding data to answer the following questions. -Use the information in Table 10.2.Suppose that overtime is allowed up to 25% of the regular-time capacity,and that overtime wages are 150% of the regular-time rate.The total cost of the level strategy with overtime and undertime,which also minimizes undertime,is:

A(n)________ seeks to optimize resources across the supply chain and align daily operations with strategic goals.

A service firm uses a level utilization production-planning horizon of six months.They have developed a forecast for the coming three quarters 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?

Earliest due date (EDD)is a priority-sequencing rule that states the job requiring the shortest processing time is the next job to be processed.

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.What would be the total plan cost if no more than five units each could be made each month by part-time,overtime,and subcontracted workers?

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?
