Smarter inventory control of spare parts can result in savings of 50%

22.11.2006
Smarter storage of spare parts is now possible thanks to a new inventory model, based on extensive cooperation between different warehouses. This method ensures the integration of inventory control for all parts in stock at several warehouses.

This way both the number of parts in stock and the waiting time for spare parts can be reduced, with theoretical savings of up to 50%. This is possible thanks to fundamental mathematical models developed by PhD candidate Bram Kranenburg MSc. With his research Kranenburg hopes to obtain a doctorate from the Technical University Eindhoven (TU/e) on Thursday 23 November.

Big Business

The storage of spare parts is big business in the Netherlands, involving billions of euros every year. Every branch of industry or service that works with complex machinery needs spare parts. Just think of electronics, hospitals, industrial machinery, and the car industry. One small, defective part can put a complete machine out of operation for quite some time. That is why there have always been strict requirements for stocking and distributing spare parts.

Pooling storage facilities

A great deal of research has already been done to optimize the entire logistic process. Still, inventory control is usually done separately for each warehouse. ASML approached the TU/e to find out if there was not a smarter way to do this and this question became a central theme in Kranenburg’s PhD research. Kranenburg: “The crux of my model is the pooling of different warehouses. If a local warehouse does not have a certain part in stock, it can contact another local warehouse instead of the central warehouse. If you want to do this on a structural basis, there is much to be won by planning your inventory control around this. But if you want to do this right, it becomes very complex mathematically to work this all out. That is the problem I worked on in my PhD research and ASML has been able to implement my model and algorithms right away.”

Universally applicable

The models are very relevant to everyday practice and can lead to great savings. Kranenburg: “Some theoretical data sets yielded cost reductions of up to 50%!” In his research Kranenburg further worked on models for integrated inventory control for different machines and for different groups of customers. All models are universally applicable. In his next job as consultant with CQM Kranenburg will strive to further increase the applicability of his research.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
