Correctly dimension
your inventory levels

Access the live demo
[space] Correctly dimensioning the inventory across the network is important in today’s complex supply chains. FrePPLe computes safety stocks and reorder quantities for raw materials, intermediate products and end products. [space] This helps companies to:
  • Reduce the inventory costs
  • Prevent stockout situations
  • Improve customer service levels
  • Eliminate manual processes

Safety stock calculation

Safety stock accounts for supply and demand variability
The safety stock is the lowest level of the point in the inventory saw-tooth profile. It is required to account for the uncertainty during the lead time:
  • Uncertainty about the customer demand
  • Variable supplier performance
[space] For every buffer, the safety stock level can be defined in one of the following ways:
  • Customer service level: FrePPLe will select the most relevant mathematical distribution to calculate a safety stock meeting the service level you want to achieve
  • Fixed quantity: The safety stock is not calculated but set to a default value given by the planner
  • Periods of cover: The safety stock will be set to the forecasted demand for a given time window

Reorder quantity calculation

Optimize the reordering frequency
How often a replenishment should be ordered from a supplier is a recurrent question for a planner. FrePPLe can model the batch ordering of parts at any location by calculating the reorder quantity using one of the following methods:
  • Economic order quantity: The reorder quantity will be calculated based on the Wilson formula
  • Fixed quantity: The reorder will not be calculated but will be set to a default value given by the planner
  • Period of cover: The reorder quantity will be set to the forecasted demand for a given time window

Define stocking rules at aggregate level

It is not possible to manage inventory policies (minimim service level, minimum ROQ…) at item-location level for large supply chains. FrePPLe introduces the concept of segments and business rules to apply inventory policies to many item-locations at once.
  • Segments are a collection of item-location combinations sharing some properties defined by the planner (E.g: Fast moving items in warehouses).
  • Business rules allow the planner to set inventory policies to segments (Minumum service level 95% for fast moving items in warehouses.

Replenishment orders generation

Optimize the replenishment process
FrePPLe will generate replenishment orders for all item-locations in your supply chain to meet the customer demand. These repenishment orders are composed of:
  • Purchase orders: Orders to your suppliers with a supplier selection logic applied.
  • Distribution orders: Replenishment orders between two locations within your supply chain.
  • Rebalancing requests: frePPLe identifies excess inventory and proposes requests to send this excess back to parent location.
