“…Thus, states representing norm fulfilment, violation, and other changes in the status of a norm must be encoded as part of the FSM. Molina-Jimenez et al (2004) also specify a contract as sets of finite state machines, one for each party, so that the parties taking part in a contract can monitor their own activity and know what they can or must do next to ensure they meet their obligations and permissions. As with our approach, state changes in the FSMs are triggered by state change, where these changes correspond to communicative acts taking place.…”

The behaviour of autonomous agents may deviate from that deemed to be for the good of the societal systems of which they are a part. Norms have therefore been proposed as a means to regulate agent behaviours in open and dynamic systems, where these norms specify the obliged, permitted and prohibited behaviours of agents. Regulation can effectively be achieved through use of enforcement mechanisms that result in a net loss of utility for an agent in cases where the agent's behaviour fails to comply with the norms. Recognition of compliance is thus crucial for achieving regulation. In this paper, we propose a general framework for observation of agents' behaviour, and recognition of this behaviour as constituting, or counting as, compliance or violation. The framework deploys monitors that receive inputs from trusted observers, and processes these inputs together with transition network representations of individual norms. In this way, monitors determine the fulfillment or violation status of norms. The paper also describes a proof of concept implementation of the framework, and its deployment in electronic contracting environments.

“…service response time), as stipulated by preestablished SLAs. These probes can also capture runtime environment faults when the service encounters a particular operational condition or a failure state (Molina-Jimenez et al, 2004). Additionally, the Fault Monitor can analyse the process execution trace logs to infer a potential problem.…”

Web services composition is gaining acceptance as a standards-based approach to automate business processes. A key resulting challenge is to ensure adaptive composition enactment to adapt to changing operating conditions such as the failure or QoS degradation of one or more constituent services. However, adaptability is not yet adequately supported by current service composition platforms. Additionally, the adaptation logic is often scattered and tangled with the specification of the base process. Consequently, this negatively impacts maintainability and adaptability. To address these issues, this paper proposes an extensible set of adaptation policies to declaratively specify exception handlers for typical exceptions in service-based business processes. The identified constructs were incorporated into a lightweight service management middleware named Manageable and Adaptive Service Composition (MASC) to transparently enact the adaptation policies and facilitate the monitoring and control of managed services. Several experimental results using a Loan Broker process illustrate the effectiveness of our approach to providing adaptive services.Keywords: adaptive web processes; policy-driven management; web services middleware.Reference to this paper should be made as follows: Erradi, A. and Maheshwari, P.

“…This is accomplished typically through the use of FSMs (see Molina-Jimenez et al 2004 for comparable approaches). As the service is being executed, the Management block will keep track of the exact status of the execution ( Fig.…”

With a steady pace of adoption of service-oriented architecture, enterprises have made significant progresses in implementing various kinds of Web services and converting existing applications to service-oriented architecture. As a significant number of services have been put into actual use, many service-oriented enterprises are faced with the problem of how to manage these services efficiently. In this paper, we propose a model-driven framework for a more efficient management of these services. In this framework, the creation and maintenance of enterprise integration solutions are modeled by flows, finite state machines (FSMs), role-based access control (RBAC) among other formal systems models as well as appropriate decision models. For instance, each enterprise integration solution would be modeled as composite services that can be described by respective flow, FSM and RBAC models. These solution models can then be stored, and later retrieved for the execution of these composite services. Furthermore, formal systems and decision models are also used to maintain and update these service-oriented solutions to improve the efficiency and quality of service management by taking advantage of the underlying service-oriented architecture.
