Table 15.7 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 15.7 and the first-come,first-served (FCFS)rule,what is the average days past due?

Table 15.2 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 15.2.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:

An example of revenue management is:

Table 15.3 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 15.3.Use a level strategy with overtime and undertime.Minimize undertime by maximizing overtime during the peak period.If the firm does not pay undertime,what is the total cost of the staffing plan including the cost of regular wages,hiring,and layoffs?

Table 15.10 A work center has the following six jobs waiting to be processed (all times are shown in days): -Use the information in Table 15.10.Which job will be the first one completed if scheduling is done using the earliest due date (EDD)rule?

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.
