Various Use Cases related to Initial Provisioning (IP) are handled under this functionality.
Initial Provisioning and Inventory Optimisation
Initial Provisioning based on a Poisson Approach
Traditionally, Initial Provisioning (IP) has been carried out using a conventional Poisson-based approach where inventory quantities are calculated separately for each part based on a Protection Level target, taking into account Fleet Size, Flight Hours (per aircraft), Mean Time Between Unscheduled Removals (MTBUR), Repair Turnaround Time and Quantity per Aircraft.
The IP function can calculate these IP quantities directly for all part numbers for each location to be considered and determine the overall Service Level that can be achieved.
Inventory Optimisation for Fleet Ramp-up and Ramp-down
An increase in the fleet size or an introduction a new fleet leads to a requirement for additional inventory to support this increase. Fleet ramp-ups generally take place in stages with delivery of aircraft, leading to a stage-by-stage increase in the level of spare parts required. Likewise, a decrease in the fleet size due to a phase-out of a fleet leads to a decrease in the required inventory support the fleet.
The Inventory Optimisation function enables determination of how many additional spares are necessary at each stage of a fleet ramp-up including the location it should be optimally placed, as well as the optimal inventory at each stage of a fleet ramp-down to identify opportunities for sales of excess units and/or repair delays.
In an environment where a Component Service Providers provides component support services to several airlines operating the same aircraft platform from the same spare parts pool, the addition of a new airline to the existing pool leads to a requirement for additional spares to support this airline and to maintain the overall performance.
The Sales Campaign function allows determination of how many additional spares would be required to support the new airline from the pool and where these spares should be placed.
Home Base Adjustment
Any change in the flight network, fleet size, part support at airports etc. will lead to a change in the level of inventory an airline needs to hold at its Home Base (Main Base).
The Homebase Adjustment function takes into consideration all these changes and provides solutions to how much optimal inventory is necessary at the Home Base.
