Abstract : This thesis studies decentralized management of business processes in the context of service oriented architectures. We present a generic approach that enables decentralized executions with cooperating processes by implemeting the centralized semantic with P2P interactions. Precisely, we present our method that derives the latter. We focus on the sophisticated control/data flow and conversational aspects that run counter to naive intuition, most of which, we explain using deeper analysis of the algorithms and data structures that we employed. In the second part of the manuscrit, we focus on information flow control that consists of planning the interactions of composed services in order to satisfy different security restrictions concerning the propagation of information in a composition. We examine the questions of what the information flow is and how it can be modeled and computed in service-oriented business processes. We present the design and implementation of a decentralized workflow management solution for the control of information flow. The derived process fragments are deployed on composed services and they enable them to establish P2P interactions with each other with respect to information flow policies. The last contribution takes on the challenge of implementing dynamic and decentralized process deployment following the same approach. Our conceptual contributions are implemented with state-of-art technologies.
