4. Research framework
• The capital goods lifecycle:
• Each stage presents different topics to investigate. Design and exploitation
stages seem most interesting and most relevant for AM & service logistics

5. Topics in the exploitation stage
1) Current service supply chains are usually multi-echelon structures.
• Which conditions cause a shift to a series of independent single-echelon
systems? Take into account:
− Lead times
− Component costs
− Reliability
2) Some critical components have very long lead times. To protect
against downtime they must be stocked.
• Could AM be used to provide temporary replacements, buying time to
source the regular component or complete a mission?

6. Topics in the design stage
Introduction to WP2 611/12/2015
• Shifting to AM requires (re)visiting the design stage
• Quantify the required investment
• Quantify performance benefits and logistical benefits
• There is scientific work on interactions between (re)design stage
decisions and total cost of ownership (TCO)
• Some of our work will be positioned there
