Doctoral thesis / dissertation from the year 2010 in the subject of computer science - applied, grade: 1, Technical University of Graz (Institute of Geoinformation), course: Geoinformatics, language: English. Abstract: The application of real-time spatial optimization in a spatial decision support system, utilizing geographic information science and technology, is demonstrated using the example of wood supply chain management. Interdisciplinarity is a key concept, as geographic information science, operations research, and spatial decision support systems are integrated. Service-oriented architectures enable the development of an architecture that consists of several, even spatially dispersed, hardware and software components. This approach ensures a fail-safe architecture and paves the way for ubiquitous computing and spatial data infrastructures. Additionally, spatial data can be gathered and transmitted.
