Service Composition and Coordination
(KM-SC)

Service composition optimization relies on the two key elements: (i) up-to-date knowledge about quality parameters of the participating services and (ii) a measure of the sub-optimality of the composition. The latter is measured with the help of a so-called utility function, which aggregates weighted measurements of single quality properties of the involved services (e.g., cost, reliability, availability, performance, reputation) to calculate the composition optimality [CD-JRA-1.2.2].


Service Infrastructure
(KM-SI)




Generic
(domain independent)

Optimization of a Service-Based Application is the process of modifying an application to make some aspect of it work more efficiently or use fewer resources. [PO-JRA-1.2.1]
In  mathematics computational science, or  management science mathematical optimization (alternatively,  optimization or  mathematical programming) refers to the selection of a best element from some set of available alternatives. [Wikipedia]
