This thesis presents an approach for the adaptation of contract-based service coordination. The approach proposes the dynamic adaptation operations: the re-invocation of a service method, the substitution of service methods and the substitution of activities. These operations allow adapting the exceptions during the execution of a coordination to guarantee its execution successfully. The main contribution of this thesis is the model of contract-based dynamic service coordination. For the adaptation of coordination, it model provides: - Concepts of classification of methods which allows o define the equivalent methods and the mappings between their interfaces (inputs, outputs) to solve its incompatibilities and, - Concept of adaptability contract which allows explicitly specifying the reactions reacting to the exceptions specified by guaranteeing QoS required.
