Biography
Christian Markl studied Computer Sciences at the TU München (TUM) where he finished his studies with a diploma. In his diploma thesis he analyzed the Performance Metrics of DTP Systems in applying the well-known Queueing Theory.
Since August 2007 Christian is working as a research assistant at the Chair of Decision Sciences & Systems (DSS) of the TU München.
Fields of Interest
- Performance Modelling
- Performance Management
- Capacity Management
- Time Series Analysis
Research Project
- THESEUS/TEXO
-
- THESEUS is a research program initiated by the German Federal Ministry of Economy and Technology (BMWi), with the goal of developing a new Internet-based infrastructure in order to better use and utilize the knowledge available on the Internet. To this end, application-oriented basic technologies and technical standards are to be developed and tested under the umbrella of THESEUS. The expected results are novel products, tools, services, and business models for the World Wide Web, as well as for the service and knowledge society of tomorrow. THESEUS is the german project with the highest public founding, including enterprises like SAP and Siemens, and a number of academic institutions.
- The aim of the TEXO application scenario within THESEUS is to provide businesses with an infrastructure for new web-based applications and services, on the basis of service oriented architecture (SOA); this infrastructure will be independent of any individual company and provide a flexible, semantic-driven interface between service providers and their customers.
- Christian's work in TEXO addresses the task of predicting performance measures like response times in orchestrated business processes.
