MRO spare parts features

Lanza is specialized in supporting MRO spare parts planning. Therefore, there are several functionalities tailored specifically to the complexities of the MRO spare parts environment: slow mover management, repairable management, supersession, and where-used information (e.g., BOM).

Slow mover management

Lanza offers specialized forecasting algorithms to tackle the challenges of forecasting slow moving-parts. Because of the lack of data, regular forecasting methods often do not provide accurate results.

  • Croston forecasting
    The Croston-forecasting method is specifically designed to forecast parts with intermittent demand. This makes it applicable to slow moving-parts, where due to the infrequency of demand, demand is often intermittent.
    Croston separately forecasts the demand size (if there is demand, how much is requested) and demand interval (what is the time between two consecutive demands). In this way, the exaggerated impact of months without demand that occurs with normal forecasting algorithms is negated.
  • Typical Demand Quantity (TDQ)
    The TDQ-method is a forecasting and inventory model in one. It is designed to suit slow movers with lumpy and intermittent demand, where regular statistics offer little value.
    The TDQ-method determines logical batches that correspond with typical amounts requested by customers. Based on the chosen stock availability target and lead time, Lanza calculates which number, or combination, of batches should be stocked to achieve the target stock availability.

 

Repairable management

Lanza offers specialized functionalities to account for the different characteristics of repairable parts. In comparison with regular consumable parts, which are discarded when broken, repairables can be repaired. This requires several different processes and considerations in the planning of repairables. Next to classifying repairable parts as repairables, making them easy to find, Lanza enables planners to account for these differences by:

  • Utilizing repair and purchase lead times
    Repairable parts have two sources of supply: new-buy and repair. Both sources can have varying lead times. To accurately predict future lead times, both sources should be considered. This is done by calculating the weighted average of the new-buy and repair lead times using the scrap rate (see below).
  • Calculating scrap rates
    The scrap rate represents the percentage of parts that is beyond-repair after breaking down. So, simplified: how many parts can still be repaired after failure. This rate is calculated using scrap lines.
  • Offering insight into the repair chain
    Visibility in the inventory within your repair chain, whether your parts are on stock, in repair, defect, or in supply.

 

  • Enabling dedicated repairable valuation
    After defining the part repair costs, Lanza is able to valuate defect and ready-for-use stock differently, giving more accurate insight into the actual value of your inventory.

 

Supersession

Lanza offers several functionalities regarding supersession and interchangeability-relations. Supersession is when one part is replaced by a new part, while interchangeability indicates whether parts can be used in each other’s place.

There are three types of part relationships: predecessor (old part that is replaced by a new part), successor (new part that replaces an old part), two-way interchangeable (parts that are identical for practical purposes, both parts can be used in the place of the other). With these part relationships, Lanza offers the following functionalities:

  • Supersession visibility
    Visualize your part relations by connecting all superseded and interchangeable parts.
  • Adopt relevant behavior
    Merge demand patterns, lead times and stock levels for all predecessors and successors and use the updated input for calculating solid inventory parameters for all active parts.

 

Where used-information

Lanza offers the ability to use where used-information in decision-making. Where used-information indicates in which as asset or line replaceable unit (LRU) a component is used. This often is often gathered from the bill of material (BOM) if available.

  • Findability of underlying components
    Visualize underlying components and quantities on a part-level. Moreover, find parts that are related to certain (sub)assets using the Focus-app.
  • Adopt relevant behavior
    When assets phase in or out, changing the total number of active assets, this can be incorporated into the demand forecast when relevant.
