Chapter 13, Problem 5PA
Summary Introduction
Interpretation:
Costs of level and chase demand production plans.
Concept Introduction:
Chase strategy is a strategy used by company to meet uncertain demands of customers. Company produces so much goods that there is enough inventory for end users. This strategy is used usually by companies to optimally reduce cost of inventory.
Expert Solution & Answer
Answer to Problem 5PA
The total cost using chase strategy is $546,240.
Explanation of Solution
Given information:
| Month | J | F | M | A | M | J | J | A | S | O | N | D |
| Litres (1000s) | 200 | 120 | 75 | 40 | 15 | 7 | 5 | 10 | 30 | 70 | 120 | 130 |
Following is the step wise calculation of level strategy (Note − units in 1,000 liters)
Following is the calculation of holding inventory Holding inventory = Normal Production + On-hand inventory − Demand
Holding inventory = 100 + 90 − 200
Holding inventory / Shortage = 10
The holding inventory / shortage is 10 units
Following is the calculation of Normal Production cost Normal Production cost = Normal production
Normal Production cost = 90
Normal Production cost = $36,000
Following is the holding cost Holding cost = Holding inventory
Holding cost = 15
Holding cost = $450
Following is the total cost Total cost = Normal production cost + Holding inventory cost
Total cost = 36000 + 450
Total cost = $36,450
Following is the calculation of level strategy

Total cost 517,230The total cost using level strategy is $517,230 Following is the step wise calculation of chase strategy
(Note − units in 1,000 liters)
Following is the Overtime cost
Overtime cost = Normal production cost + Normal production cost
Overtime cost = 400 + 400
Overtime cost = 400 + 80
Overtime cost = $480
Following is the Undertime cost
Undertime cost = Normal production cost + Normal production cost
Undertime cost = 400 + 400
Undertime cost = 400 + 48
Undertime cost = $448

A manager is attempting to put together an aggregate production plan for the coming nine months. She has obtained forecasts of aggregate demand for the planning horizon. The plan must deal with highly seasonal demand; demand is relatively high in months 3 and 4, and again in month 8, as can be seen below:
The company has 20 permanent employees, each of whom can produce 10 units of output per month at a cost of $6 per unit. Inventory holding cost is $5 per unit per month, and back-order cost is $10 per unit per month. The manager is considering a plan that would involve hiring two people to start working in month 1, one on a temporary basis who would work until the end of month 5. The hiring of these two would cost $500. Beginning inventory is 0.Start with 20 permanent workers. Prepare a minimum cost plan that may use some combination of hiring ($250 per worker), subcontracting ($8 per unit, maximum of 20 units per month, must use for at least three consecutive months), and overtime…

- evelop a production plan and calculate the annual cost for a firm whose demand forecast is fall, 9,700; winter, 8,000; spring, 7,000; summer, 11,700. Inventory at the beginning of fall is 485 units. At the beginning of fall you currently have 35 workers, but you plan to hire temporary workers at the beginning of summer and lay them off at the end of summer. In addition, you have negotiated with the union an option to use the regular workforce on overtime during winter or spring only if overtime is necessary to prevent stockouts at the end of those quarters. Overtime is not available during the fall. Relevant costs are hiring, $80 for each temp; layoff, $160 for each worker laid off; inventory holding, $5 per unit-quarter; backorder, $10 per unit; straight time, $5 per hour; overtime, $8 per hour.

John has years of food processing experience, and Mavis has extensive commercial food preparation experience. The process will consist of opening crates of lettuce and then sorting, washing, slicing, preserving, and finally packaging the prepared lettuce. Together, with help from vendors, they think they can adequately estimate demand, fixed costs, revenues, and variable cost per 5-pound bag of lettuce. They think a largely manual process will have monthly fixed cost of $50,000and a variable cost of $2.50 per bag. They expect to sell 75,000 bags of lettuce per month. They expect to sell the shredded lettuce for $3.25 per 5-pound bag. John and Mavis has been contacted by a vendor to consider a more mechanized process. This new process will have monthly fixed cost of $125,000 per month with a variable cost of $1.75 per bag.
