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: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
