A Supply Chain Planning Case Study

  • Needed efficient and optimized replenishment of nine secondary warehouses from central distribution
  • SO99+’s flexibility made for straightforward SAP ERP integration
  • Service level improved while reducing inventory

Project and Objectives

Repsol was seeking to achieve customer service excellence (measured in order line fill rate) for their clients. In addition, they wanted to obtain:

  • Inventory reductions
  • Efficient replenishment of their nine secondary warehouses from the central warehouse
  • Precise input for manufacturing planning, MPS and MRP
SO99+ was introduced rapidly, achieving integration and co-functioning of several systems. The phases were:
  • Quantitative analysis of the base-line situation, carrying out empirical tests and quantitatively analysing the potential for desired improvements and savings
  • Alignment of SO99+’s parameters with the other manufacturing and materials management systems, and systems interfacing
  • Ongoing operation of SO99+


Repsol is now able to optimise more than 21,000 SKU-Locations in two divisions (20,000 in Lubricants and 1,200 in Paraffins). One of the characteristics most valued by Repsol is SO99+’s flexibility, which made integration with SAP and their other systems very straightforward, and also allows them to easily add new lines of business.

Results & Benefits

Repsol achieved a service level improvement from 81% up to 97%, while simultaneously reducing inventory by 16%. In addition, SO99+ enabled them to constantly maintain an optimal service policy, providing them with a reliable estimate of the cost required fulfilling any specified global service objective.

The use of SO99+ was then extended to plan the Paraffins division. Two more divisions, Asphalts & By-products and Sulphates, were added later.

With revenue in excess of $1 Billion, Repsol is a leading European manufacturer and distribution of lubricants, asphalts and by-products.
