Abstract:
Electronic contracts (e-contracts) usually describe cross-organizational business processes defining electronic services to be provided and consumed as well as constraints on service execution such as, for instance, Quality of Service (QoS). Due to market dynamism, it is common that organizations involved in a cooperation need to do some adjustments in a pre-established e-contract. These changes should be allowed through renegotiation of contractual clauses after the e-contract is already signed and being enacted. In this paper, feature modeling is used to represent electronic services (e-services), QoS attributes and control operations to be applied when QoS attribute levels are not met. In addition, an execution environment is proposed to support contract establishment, business process execution, service monitoring and contract renegotiation.
