Scenario

Cobalt Robotics is a industrial robotics business in Japan shipping about 4m orders a year on ¥985 B of revenue.

It runs 1 distribution centre today. The supply chain team has proposed moving to 2.

Current economics per order:

  • Line-haul: ¥46
  • Last-mile: ¥116
  • Average delivery time: 4 days

Under the proposed network:

  • Each additional DC costs ¥18 B a year to run
  • Last-mile falls to about ¥94 per order, because stock sits closer to customers
  • Average delivery time falls to 2 days
  • Marketing estimates faster delivery is worth roughly 4.4% of revenue in additional sales

The CFO is resisting on the grounds that fixed costs go up.

Your task

Advise on the network. Your answer should provide:

  1. Analysis — total cost-to-serve under both networks, computed.
  2. Risks — what the case depends on and what you would monitor.
  3. Recommendation — a specific number of DCs and why.

State any assumptions you make.
