Long utilization phase (long lifetime of the product)
Long production and utilization phase
Long R&D phase (intensive cooperation with customers during all phases)
Forecasting
Forecasts are possible due to the short delivery obligation

Subjective estimations and indicators and coefficients
Forecasts are hardly realizable due to long utilization phase

Stochastic and model based methods
Accurate forecasts are possible due to the huge amount of maintenance contracts

Indicators and coefficients
Accurate forecasts are possible due to a good knowledge about the condition of installed base

Indicators and coefficients
Step 3
Goals
Profits (major goal)
Differentiation (major goal), customer loyalty, diversification, profits
image (major goal), customer loyalty, profits
Customer loyalty (major goal), reputation, profits
Supply options
Due to long production phase uncomplicated supply out of the regular series production. Final stock during the utilization phase.
Internal production, utilization of compatible parts, reconditioning of used parts

Utilization of compatible parts, separate workshop, final stock
Inventory options
