  • Benefits of Additive Manufacturing

    Benefits1 for JLG Ground Support

    Simpler supply chain Shorter lead times Lower inventories

    Small production batches

    Company goal: Reduce inventory while maintaining a fill rate of 98%

    Company goal in combination with AM benefits In our project we investigate how we can use AM to meet this goal

    We need to know which parts are eligible and what criteria they must meet

    Analytical Hierarchy Process

    5 Decision makers

    Pair-wise comparison

  • Data scoring

    All candidate parts receive a score from 0 to 1 for every spare part attribute

    Normalize scores based on extreme values

    Linear scoring: Lead time Batch size/sale ITR

    Logarithmic scoring: cost

    Other scoring: Demand
