Helping small firms run large supply chains

19.01.2006


Big manufacturing jobs, especially those in the defense industry that involve management of extensive supply chains, often require resources and expertise that many believe are beyond the capacity of small and medium-sized enterprises (SMEs). Recent work by researchers at the National Institute of Standards and Technology (NIST) and colleagues at Pittsburgh’s Doyle Center for Manufacturing Technology, however, demonstrates the capabilities of simulation and visualization technologies for improving SME supply chain expertise.



The proof-of-concept test involved SME management of a 10-enterprise subassembly supply chain for a major aircraft engine component. The Doyle Center collected data for the simulation model often using questionnaires and personal visits to suppliers. NIST and Doyle researchers then adapted a commercial software program to build an accurate visualization and analytical simulation model for the supply chain enterprise.

The finished program allowed a small firm to know what would happen at any given time during the flow of material through the chain. Data inputs enabled it to use supplier production rates, inventory numbers and shipment times for components. The model identified prospective supply chain performance at "normal," "surge" (twice normal) and "mobilization" (four times normal) production rates. When the program uncovered potential bottlenecks in the supply chain, the team used the program to evaluate potential impacts and to implement solutions to mitigate risks and reduce costs.


NIST presented a detailed description of the project at the 2005 Winter Simulation Conference in December. "Stress Testing a Supply Chain Using Simulation," the NIST paper by Sanjay Jain and Swee Leong, is available at http://www.informs-sim.org/wsc05papers/203.pdf.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
