Chapter 11, Problem 12P
Summary Introduction
To determine: The minimized total cost using aggregate planning
Introduction: The aggregate plan is the output of sales and operations planning. The major concern of aggregate planning is the production time and quantity for the intermediate future. Aggregate planning would encompass a time prospect of approximately 3 to 18 periods.

Given the projected demands for the next six
months, prepare aggregate plan must wind up
with no units in ending inventory in Period 6.
Regular time capacity is 150 units per month.
Overtime cost is $20 per unit, backorder cost is
$30 per unit, inventory holding cost is $10 per
unit based on maximum, subcontracting cost is
$40 per unit, regular time cost of $20 per unit,
and beginning inventory is 10.
Month 1 2 3 45 6
Forecast 150 170 140 160 130 160
a. Prepare an aggregate plan with inventory and
backlog allowed. Overtime and subcontracting
are not allowed.
b. Prepare an aggregate plan if the management
decided to switch to chase strategy. They only
allow backlog if absolutely needed. Regular
production capacity is now 160.
Jill wants you to consider a hybrid aggregate plan, usingup to the maximum overtime per employee for any periodwhere demand cannot be satisfi ed with the current regular-timeproduction and the available inventory. Back orders can occur.(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 human resources
WSS company makes weatherproof surveillance systems for parking lots. Demand estimates for the next four quarters are 25, 9, 13, and 17 units. Prepare an aggregate plan that uses inventory, regular time, and over time, and backorders. Subcontracting is not allowed. The regular time capacity is 15 units for quarters 1 and 2, 18 units for quarters 3 and 4. Overtime capacity is 3 units per quarter. The regular time cost is $2000 per unit, while the overtime cost is $3000 per unit. Backorder costs $300 per unit per quarter; inventory holding costs $100 per unit per quarter. The beginning inventory is zero.
How many total units will be produced in quarter 1 for delivery in quarter 1?
How many units in total will be used to fill back orders over the four quarters?
What is the cost to produce one unit in Quarter 4 using overtime to fill a back order in quarter one?

- Planners for a company that makes several models of skateboards are about toprepare the aggregate plan that will cover six periods. They now want toevaluate a plan that calls for a steady rate of regular output, mainly usinginventory to absorb the uneven demand but allowing some backlog. Overtimeand subcontracting are not used because they want a steady output. They intendto start with zero inventory on hand in the first period. Prepare an aggregate planand determine its cost using the following information. Assume a level of outputrate of 300 units per period with regular time. Note that the planned endinginventory is zero.

- Using the cut-and-try method for aggregate operations planning, as described in the textbook, we can calculate ending inventory and safety stock as a percent of forecast demand.
