Designing Global Supply Chain Networks

Chapter 6 - Designing Global Supply Chain Networks

- Exercise 2 (page 170)

Unipart, a manufacturer of auto parts, is considering two different B2B marketplaces to purchase its MRO supplies. Both marketplaces offer a full line of supplies at very similar prices for products and shipping. Both provide very similar service levels and lead times. However, their fee structures are quite different. The first marketplace, Parts4u.com, sells all of its products with a 5 percent commission tacked on top of the price of the product (not including shipping). AllMRO.com's pricing is based on a subscription fee of $10 million that must be paid up front for a two-year period and a commission of 1 percent on each transaction's product price.

 

Unipart spends about $150 million on MRO supplies each year, although this varies with their utilization. Next year will likely be a strong year, in which high utilization will keep MRO spending at $150 million. However, there is a 25 percent chance that spending will drop by 10 percent. The second year, there is a 50 percent chance that the spending level will stay ~here it was in the first year and a 50 percent chance that it will drop by another 10 percent. Unipart uses a discount rate of 20 percent. Assume all costs are incurred at the beginning of each year (so Year 1's costs are incurred now and Year 2 costs are incurred in a year).

Which B2B marketplace should Unipart buy its parts from?
