The globalization of markets characterized by increasing networking of economy, result in a strong competition of worldwide producing companies. These companies face challenges evented by individual products and short production times. This requires planning fundamentally refocuses on production and logistics which are highly complex supply chain processes. To handle the amount of information, companies currently use various slides and spreadsheets and documents or personally meetings in project rooms. The distributed and heterogeneous representation of the complex interactions reduce transparency and hamper the understanding of processes. A technology which offers an interesting approach to solve these Problems is the new technology of the Rich Internet Applications (RIA). RIAs are a new kind of web-based applications, equivalent to traditional desktop programs in their performance, capabilities and display options. In this paper this technology is used to design and implement a RIA for the planning and visualization of modern supply chain processes.
