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

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?

Topics in the design stage

• 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
