Supply Chain Management



Low inventories and high service levels !


Identification of STOCK DRIVERS

Optimization of MRP PARAMETERS


Lowering inventory levels frees up capital and increases liquidity that you neither have to pay off nor pay interest on.

Using a digital twin of your ERP system, we uncover the critical points, calculate the effectiveness of various measures and thus identify the economically viable strategies.

We implement this together with you, and ensure that your inventories remain low in the long run while your service level is maintained or increased.

Abels & Kemmner helps leading companies to optimize their inventory management!

Optimized inventory management

Fabian Ossen

Supply Chain Manager, Sihl GmbH

"A&K showed us the path to having the clearest possible understanding of our inventory. The fact that A&K also implemented and achieved the results together with us was a decisive factor.

A&K's simulative analysis of our global value chain showed us the critical points for increasing our product availability while significantly reducing our inventories."


In 75% of customer projects, we achieve an inventory reduction of at least 20%.

Using the data from your ERP system, we build a digital twin of your value streams and planning processes. This enables us to 

  • Compare possible future inventory management strategies and together with you optimize the most suitable one to your needs
  • Reduce the required effort for planners and schedulers to the necessary minimum
  • Develop approaches to raise service levels and specify reasonable safety stock levels

With the application of constraint analyses, we systematically uncover the root causes of unsatisfactory supply chains and planning processes, derive suitable improvement measures and help you implement them. Some examples of topics we often address:

  • Bottlenecks and missing parts
  • Reduction of lead times
  • Minimization of scrap rates
  • Increasing service levels
  • Supplier integration


Uncover excess stock quickly and cost-effectively!

The E:S:A method relies on item master data and analyzes it based on statistical insights gained from many detailed inventory optimization projects and inventory simulations.

Excess Stock Assessment is a special method for easily identifying excess stock in companies. With the help of the E:S:A analysis we answer the following questions at short notice, even within hours if necessary:

  • How great is your inventory reduction potential?
  • How much liquidity can you gain within six months?
  • How much inventory can be reduced in the medium to long term?
  • What can your stock reduction curve look like?
  • How can your annual yield improve?
  • How can your inventory range and inventory turnover look like in the future?

Inventory is often used as a safety net for problems in a supply chain but it masks the underlying causes. In some cases, however, having higher inventory levels can be the more cost-effective solution. Therefore, it is important to precisely identify the right elements in reducing inventories.
