3-37 Uncertainty and expected costs. Kindmart is an international retail store. Kindmart’s
managers are considering implementing a new business-to-business (B2B) information system
for processing merchandise orders. The current system costs Kindmart $2,000,000 per month and
$55 per order. Kindmart has two options, a partially automated B2B and a fully automated B2B
system. The partially automated B2B system will have a fixed cost of $6,000,000 per month and
a variable cost of $45 per order. The fully automated B2B system has a fixed cost of $14,000,000
per month and a variable cost of $25 per order.
Based on data from the past two years, Kindmart has determined the following distribution
on monthly orders:
Required:
1. Prepare a table showing the cost of each plan for each quantity of monthly orders.
2. What is the expected cost of each plan?
3. In addition to the information system’s costs, what other factors should Kindmart consider
before deciding to implement a new B2B system?
SOLUTION
(30 min.) Uncertainty and expected costs.
1. Monthly Number of Orders Cost of Current System
300,000 $2,000,000 + $55(300,000) = $18,500,000
Monthly Number of Orders Cost of Partially Automated System
300,000 $6,000,000 + $45(300,000) = $19,500,000
Monthly Number of Orders Cost of Fully Automated System
300,000 $14,000,000 + $25(300,000) = $21,500,000
2.
Current System Expected Cost:
$18,500,000 × 0.25 = $ 4,625,000
$30 ,050,000
Partially Automated System Expected Cost:
$19,500,000 × 0.25 = $ 4,875,000
$28 ,950,000
Fully Automated System Expected Cost:
3. The fully automated system has the lowest expected cost. Before making a final deision,
Kindmart should consider the impact of the different systems on its relationship with suppliers.
