14 Operational requirements The implementation of LCC models Definition of cost break down structure Global approach mean values for the top level items Example Advantages Disadvantages re-investment cost for track and components, mean life time grinding cost per track meter and year fast analysis and rough estimation of LCC basis for sensitivity analysis easy development of models, easy check of models easy documentation no detailed analysis, no dependencies, several LCC models necessary validation for new systems difficult 14

15 Operational requirements The implementation of LCC models Definition of cost break down structure Detailed approach split up of values for investment, maintenance... Example Advantages Disadvantage re-investment cost split up in material, transport etc., mean life time grinding cost per shift, shift performance, grinding detailed LCC and sensitivity for given boundaries, easy check of models validation of input data no dependencies several LCC models necessary for several cases detailed data necessary more time for development and validation 15

16 Operational requirements The implementation of LCC models Definition of cost break down structure Functional approach use of functions and expression and dependencies Example Advantage Disadvantage load and process dependent re-investment cost and life times dependencies regarding grinding machine, metal removal, growth rate of cracks and maintenance strategy very detailed LCC analysis possible all relevant calculation possible with one model mixture of component and maintenance strategies easy extendable, control of boundaries from PBS complexity of models, detailed data necessary, check of model complex documentation 16

17 Operational requirements View on the LCC Technical view View on components, sub systems or System Necessary for modular LCC models Results are structured by components 17

18 Operational requirements View on the LCC Economical view View on cost items at different levels Results are structured by cost items 18

22 LCC the most important basis for decision Why LCC in optimization process? Status Quo Innovation/Optimization Economical effects Technical performance Reliability Availability Maintainability Environmental perform. Noise Ground born vibration Costs (drivers) Investment Operation Maintenance Non availability Technical performance Reliability Availability Maintainability Tolerance against conditions ; Environmental perform. Noise Ground born vibration ; Change in Costs... Life cycle costing Change in initial investment (t=0) Migration costs Costs for new regulations Decreasing costs for environmental sustainability Decrease maintenance cost Decrease costs for non availability Additional income? Decision by Life Cycle Cost Traffic prognosis Social economical effects 22

28 Often LCC for infrastructure starts at installation or operation Important phase of development is neglected Development Construction LCC for Infrastructure (Prototype) (Test) Production Installation Operation End of life Disposal Procurement (buyer costs) Operational costs (operation, maintenance, Non-availability) Procurement costs + = LCC

29 Minimal LCC requires close cooperation between suppliers and operators Phases of Life Cycle Costing Commissioning 250 Costs Component level Manufacturer Transport and installation costs Manufacturing costs Operator System level Development costs Development, manufacturing and installation Operation 29

30 System optimization requires monitoring and feedback to the suppliers Phases of Life Cycle Costing Influence on LCC 1 Low High 0 0 Investment - material Life time Long-term behaviour Supplier/Contractor Development, manufacturing installation Investment - installation Quality Time to market Infrastructure manager Operation Maintenance 30
