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: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
