Noin 40 kahtena vuonna jäsenmaksunsa laiminlyönyttä jäsentäpoistettiin yhdistyksen jäsenrekisteristä vuoden 2006 loppuun mennessä.

a. Calculate the aggregate production rate.b. Calculate the appropriate workforce given the aggregate production rate.1.2-) Jill Nicholas has decided that you should develop a level aggregate plan, using theaggregate production rate and workforce calculated in Problem 1.1a. Show what would happen if this plan were implemented.b. Calculate the costs this plan.c. Evaluate the plan in terms of cost, customer service, operations, and humanresources.1.3-) Jill has decided that the Backpack Company must have very good customer service.She has asked you to develop a level aggregate plan using inventories but not backorders.All demand must be met each period. You must calculate the:a. Aggregate product rate.b. Appropriate workforce given the aggregate production rate.1.4-) Continue developing a level aggregate plan using inventories and no back orders. Usethe aggregated production rate and work force calculated in Problem 1.3.a. Show what would happen if this plan were implemented.b. Calculate the costs of this plan.c. Evaluate the plan in terms of cost, customer service, operations, and humanresources.1.5-) While the Backpack Company has always used a level aggregate plan, Jill isinterested in evaluating chase aggregate plans also. She has asked you to calculate howmany hires and fires would be necessary to adjust capacity to meet demand exactly eachperiod. If necessary, incur some under-time. Calculate the number of workers needed eachperiod.1.6-) Now that you have calculated the number of workers needed each period in Problem1.5, Jill wants to see how the plan would actually work. You need to:a. Show what would happen if this plan were implemented.b. Calculate the costs associated with this plan.c. Evaluate the plan in terms of cost, customer service, operations, and humanresources.1.7-) Jill Nicholas is concerned about Backpack's corporate image and has decided againstusing hires and fires. Instead, she has asked you to consider a chase aggregate plan usingthe current workforce supplemented by overtime or under-time to change capacity asneeded. She has asked for the following information from you.a. How many production hours would be required each period to produce the exactquantity demanded?b. How many regular time production hours are available each period?c. How many overtime time production hours would be needed each period?2

1.8-) Based on your calculations in Problem 1.7, Jill wants you to complete a chaseaggregate plan using the current workforce supplemented by overtime or under-time.a. Show what would happen if this plan were implemented.b. Calculate the costs for this plan.c. Evaluate the plan with regard to cost, customer service, operations, and humanresources.1.9-) Jill Nicholas believes there must be a better aggregate plan. She has suggested ahybrid aggregate plan, using a permanent workforce of 195 employees and subcontractingas needed. Once again, Jill has requested some preliminary calculations from you.a. Calculate the regular time production possible each period given a workforce of195.b. Calculate the number of units you must subcontract each period. Note that whenyou subcontract, you must buy a minimum of 500 units. You can subcontract up to 1000units in any given period.1.10-) Based on your initial calculations in Problem 1.9, Jill has asked you to complete ahybrid aggregate plan using a permanent workforce of 195 employees supplemented bysubcontracting.a. Show what would happen if this plan were implemented.b. Calculate the costs associated with this plan.c. Evaluate the plan in terms of cost, customer service, operations, and humanresources.1.12-) Jill wants you to consider a hybrid aggregate plan, using 195 permanent employeessupplemented by overtime. Calculate the number of overtime hours needed each period.Do not exceed the overtime limit of 32 hours per employee per period.1.13-) Complete your hybrid aggregate plan, using 195 permanent employeessupplemented by overtime.a. Show what would happen if this plan were implemented.b. Calculate the costs associated with this plan.c. Evaluate the plan in terms of cost, customer service, operations, and humanresources.3
