Conclusions
and Future Work

47. 4th International Workshop on Information Systems in Distributed Environment
Graz, Austria, 13th September 2013
• Methodology for adapting component-based software systems at
runtime
• Architectural models in two levels:
– Abstract (PIM perspertive)
– Concrete (PSM perspective)
• Resolve PSM models from PIM definition at runtime
• Using a trading process for realizing the concrete architectural
models (PSM) in six stages:
– Selection of candidate components
– Calculation of configurations
– Closure of configurations
– Calculation of compliant configurations
– Application of heuristics
– Building the concrete architectural model
Conclusions

48. 4th International Workshop on Information Systems in Distributed Environment
Graz, Austria, 13th September 2013
• Generates the configuration of concrete components that best
meets the abstract definition
• Provides the possibility of generating different configurations of
sofware architectures based on the same abstract definition
• Uses information about the meaning given by the functional and
non-functional properties of the components: Semantic Trader
Conclusions

49. 4th International Workshop on Information Systems in Distributed Environment
Graz, Austria, 13th September 2013
Future Work
• We assume that at least one valid configuration will be resolved
• Alternative resolution mechanism if there is not resolved a valid
configuration
• Resolution of mismatches (e.g. incompatibilies of components)
• Implement searching algorithms (calculation of configurations)
based on heuristics to perform tree pruning
