“…Schulz et al [4] have introduced the concept of view based coalition workflows. Chiu et al [27] present a meta model of workflow views and their semantics based on supply chain e-service but their model lacks an integrated cross-organizational perspective.…”

“…To achieve this balance between privacy and trust we have introduced the concept of SLA Views that plugs in within our validation framework. It provides a privacy similar to that of workflow views [4,8,9], where every service provider is limited to only their own view. SLA Views also complement the notion of distributed trust among the various partners in a coalition workflow [10].…”

“…SLA composition in workflows has been mostly treated [3] as a single-layer process. This single-layer SLA composition model was insufficient to describe coalition workflows [4] where a multilayered aggregation of services is required that results in supply-chain type of business networks. Therefore the research community has just started taking notice [5] of the importance to describe this hierarchical aggregation of SLAs.…”

For the Service Economy to prosper, IT-based Service Markets are required to perform certain business actions autonomically and autonomously, e.g. helping companies to establish networks of business relationships. Service Markets, to be practically realized require an enabling infrastructure that supports business-to-business (B2B) relationships among business stakehoders, resulting in value chains.B2B workflow interoperation across Virtual Organisations (VOs) brings about novel business scenarios. In these scenarios, parts of workflows corresponding to different partners can be aggregated in a producer-consumer manner, leading to hierarchical structures of added value. Service Level Agreements (SLAs), which are contracts between service providers and service consumers, guarantee the expected quality of service (QoS) to different stakeholders at various levels along this hierarchy. Automation of service composition in these coalition workflows directly implies the aggregation of their corresponding SLAs. This hierarchical choreography and aggregation poses new challenges regarding SLA description, management, maintenance, validation, trust and security. In this paper we focus on design and architecture of an agent-oriented, rule-based validation framework for hierarchical SLA aggregation, enabling cross-VO workflow cooperation. The framework is based on the Rule Responder architecture, the RBSLA project, a formal model of SLA Views, and a distributed trust model.

“…Workflow interoperability is commonly examined from a top-down view [7,8,9], which intends to start from the concept of traditional workflow and extend it beyond organisational boundaries in order to keep the control flow manageable. However, as a technology-driven approach, it brings in much initial cost in terms of a detailed and rigid pre-definition that does not reflect the run-time nature of agile interactions within VEs where many of the partnerships are dynamic and temporary.…”

Abstr act. Driven by popular adoptions of workflow and requirements from the practice of virtual enterprise (VE), research in workflow interoperability is currently on the increase. Nonetheless, it is still in its early stage compared with the maturity of individual workflow technology. Some attempts have been tried, however results are not satisfactory especially in a VE context, where many of the partnerships are dynamic and temporary. Reasons include the rigidity and high initial coordination cost inherently associated with top-down modelling and enactment approaches. Therefore, this paper proposes a bottom-up and WfMS 1 Keywor ds: Multi-Agent Systems, Workflow Interoperability, Virtual Enterprise -independent approach towards cross-organisational workflow enactment, which is via progressive linking enabled by run-time agents. This is expected to pave the way for further cross-organisational workflow needs.

Process view technologies allow organizations to create different granularity levels of abstraction of their business processes, therefore enabling a more effective business process management, analysis, interoperation, and privacy controls. Existing research proposed view construction and abstraction techniques for block-based (ie, BPEL) and graph-based (ie, BPMN) process models.However, the existing techniques treat each type of the two types of models separately.Especially, this brings in challenges for achieving a consistent process view for a BPEL model that derives from a BPMN model. In this paper, we propose a unified framework, namely UniFlexView, for supporting automatic and consistent process view construction. With our framework, process modelers can use our proposed View Definition Language to specify their view construction requirements disregarding the types of process models. Our UniFlexView's system prototype has been developed as a proof of concept and demonstration of the usability and feasibility of our framework.
