Supply Chain Management



Supply Chain - Transforming inflexible processes to agile value creation

Supply chain optimization
through simulation

By using empirical simulation, we uncover the potential of your supply chain management  and replace the fog of uncertainty with clear facts and quantified benefits.

Constraint analysis along the value chain

Using constraint analysis, we uncover the hidden bottlenecks that limit the performance of your logistics system.

Supply Chain - Customer voices


"The supply chain analysis and simulation showed us, similarly to a crash test, where there is potential in our supply chain processes and how we can leverage it.


On this basis, we have implemented solutions along the value chain that make us more resilient to disruptions and enable customer-oriented management.”

Carsten Hense

COO, Rosenthal GmbH



"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. 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."

Fabian Ossen

Supply Chain Manager, Sihl GmbH

Supply Chain - What is affecting our customers

Challenges in the field of logistics and supply chain management that companies approach us with.

We help you to make the decisive leap forward and develop lasting solutions.


Does your competition deliver more reliably?
High product availability does not necessarily require higher inventories, but rather

  • the right inventories of the right items
  • a logistically optimized product portfolio
  • better demand forecasts and the right safety stocks
  • more reliable lead times in production

Using constraint analysis and logistical simulation, we identify, quantify and implement the critical levers to increase your product availability without requiring additional capital.

In six months, you will leave your office more relaxed:

Satisfied customers, relaxed employees, higher profits!

Special tip:

An AI-powered algorithm to automatically optimize service levels can increase the market's perceived service levels while lowering required inventory levels.


Lacking an overview of inventory, delivery (in)capabilities, schedule delays and disruptions in your supply chain is like sailing through fog in shallow water.

No matter how hard everyone tries, running aground on a regular basis can hardly be avoided.

Sometimes it is due to technical deficits, such as isolated ERP silos or poor forecasts, sometimes processes are not precise or the logistics model does not fit the requirements of the market.

If technical deficits are the cause of non-transparency, we will help you to restore the information flow by tuning your ERP systems or using suitable additional tools.

If the causes are unclear, we uncover them by means of constraint analyses or logistical simulation, depending on the initial situation. 

Special tip: 

Heterogeneous ERP landscapes without a continuous flow of information do not necessarily have to be replaced by a central system. By applying suitable add-on tools, more transparency can be achieved drastically faster and in a more cost-effective way.


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

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 identify the right elements for reducing inventories.

Using empirical value stream simulation and constraint analysis, we uncover critical points, calculate the effectiveness of various measures and, thus, identify the economically viable strategies. We implement these together with you, and also ensure that your inventories remain low in the long run by using appropriate systems.

In 75% of cases, we achieve an inventory reduction of at least 20% in this way.

Special Tip: 

In most cases, inventories can be reduced significantly without jeopardizing service levels.

With our E:S:A excess inventory analysis, you can quickly, easily and cost-effectively identify whether it is worthwhile for you to reduce inventory levels.


An important element of increasing productivity in companies is to automate administrative processes.

In planning and scheduling processes, it is not enough to only eliminate and simplify work steps. It is also crucial to automate the processes through appropriate software.

For a reliably supportive ERP-system and to automate routine tasks, your ERP-system and the MRP parameters have to be set up correctly. 

Using our analysis tools and simulation software, we determine the correct item-specific settings for your ERP system and build a rulebook to maintain your system regularly and automatically. Based on an optimally adjusted and maintained system, we work with you to design new planning and control processes and identify the tasks that you can (partly) automate. This way, the planning effort can be reduced by up to 90%.

Shortly after, your planning quality will improve, and your employees will  be more motivated and able to work on more important tasks.

Special tip: 

Depending on your ERP system, up to 120 item-specific adjustments have to be made to your master data and parameters. This is a task that no one can perform without additional tools. A smart Factory begins with a smart MRP.


In its day-to-day business, the supply chain function faces constantly changing constraints and corporate requirements. This frequently necessitates ad hoc adjustments to processes and systems. This can sometimes obscure the bigger picture and lead to loss of efficiency and effectiveness.
If the supply chain management does not work as efficiently as possible, it affects many aspects, including:

  • Sales planning, production control or procurement can be too costly
  • Poor material efficiency leads to unplanned material waste
  • Your ERP system is poorly adjusted and does not support employees in their work

Using constraint analysis, we uncover the cause-and-effect network between inadequate performance and the core causes that hinder the overall performance of SCM. These are the key levers for our improvement measures, which enable us to achieve the greatest effects at the lowest costs.

Special tip:

With our structured analysis of the state of your supply chain function, you can uncover conceptual and strategic deficits in just a few workshops, which helps to limit the constraint analysis to the critical areas.
