The course work is a supply-chain project which is based on a case study and
covers:
• defining and properly describing the supply-chain problem (15%),
• building a representative simulation model for an existing system and
verifying/validating the model (45%)
• finding a solution to the problem by analysing the simulation outputs (30%)
• Structure and presentation of final report (10%).
The final report is to be a complete report starting from the initiation of the
problem to the solving and documentation (maximum 2000 words).
