    Dissertation focuses on providing services that stay in accordance with SOA paradigm, created using component technologies. To support creating and provisioning services on the customer demand, functional requirements for the services as well as functional capabilities of the components use semantic description. This approach allows the system to automate several parts of the integration process. To assure quality of service (QoS) required by the service customer, there is a necessity to adapt the service to changing non-functional capabilities of the provider infrastructure. The designed service provisioning framework adapts the service by selecting a proper set of components, which are used as a service logic implementation. This adaptation is performed using high-level policies, mapped to low-level rules. The prototype implementation of so-called "On demand Service Provisioning System" has been implemented by enhancing Service Component Architecture (SCA) technology, which is used for integration of the components created using different CBSE technologies. The presented solution has been tested using a prototype service, using set of components and sample adaptation policies.
