1 –> location DOES deliver to customer x
What is the transportation problem?
determining which customer gets what amount form which location
- location & customers are fixed
- customers have demand
- locations have capacity
How can the transportation problem be solved?
- Linear program with Excel solver
- simple heuristics like Column minima method
What is important about a heuristic?

How do you solve a p-median problem?
a small set of p locations should
be chosen out of a larger set of possible location
What trends are there in supply chain?
- digitalization
- rethinking outsourcing
- use of AI, big data, analytics
- Sustainability
- Circular supply chains
- Tracking
define Tracking
RFIDs are read using a tag reader
-allows real time information
what is active / passive tracking?
active = needs battery
passive =no battery (energy of scanner used)
