CONSOLIDATION (OF FAILING PARTS)RECAP

2

Key Findings:

Typically higher costs with consolidation, e.g.:

The more parts are consolidated the lower the benefit

Shorter replenishment lead time least interesting benefit

Nevertheless, cases with significant costs savings even if key characteristics are worse with consolidation

total cost model to decide about value of consolidation

DUAL SOURCING CONCEPT

3

CM source

AM source

Capital goods

with printable

and failing parts

Spare

part stock

When to use AM to supplement CM source?

What are the cost benefits of Dual Sourcing?

How often we use AM design relative to CM design?

RESEARCH QUESTIONS

4

Simulation model in place

Model for small instances implemented and validated

First small experiments completed

Typical result:

Consider slow moving part with stock level of 1

In case stock on hand is equal to 1 use CM

Quality/low costs > Speed

In case stock on hand is equal to 0 use AM

Speed > Quality/low costs

Cost savings of more than 20% possible

RESEARCH STATUS

5

Initial lifecycle phase (high uncertainties)

Less overstocking

Less risk of downtime

Long resupply lead times for CM parts:

Reduce stock levels

Reduce downtime

APPLICATION AREAS

6

Required input:

Characteristics of both, AM and CM design:

(Anticipated) failure behavior (maybe WP1)

Expected replenishment lead times

Expected purchasing costs

System characteristics:

Estimated downtime costs or other service measures
