Ensuring Service Level Agreements for Service Workflows
2008 IEEE International Conference on Services Computing, 2008Specifying and monitoring service level agreements (SLA) has been the subject of intensive research. However, methods of enforcing SLA have not addressed the specific issues of composite services (CS). Our work focuses on the problem of keeping prearranged SLAs for service workflows including workflows supporting long lived transactions (e.g.

Enabling service-level agreement renegotiation through extending WS-Agreement specification [PDF]
Service Oriented Computing and Applications, 2014 WS-Agreement is a language and protocol designed for creating service-level agreements (SLAs) based on initial offers, and for monitoring those offers at runtime.

Design of service level agreements for software services
Proceedings of the International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing, 2009During last years, Quality of Service (QoS) aspects in service-based applications tend to be more and more challenging issues. The paper is focused on various aspects of QoS contracts and especially on these being parts of Service Level Agreements (SLAs).

Flexible service provisioning with advance agreements [PDF]
International Joint Conference on Autonomous Agents and Multiagent Systems, 2008 In this paper, we develop a novel algorithm that allows service consumer agents to automatically select and provision service provider agents for their workflows in highly dynamic and uncertain computational service economies. In contrast to existing work, our algorithm reasons explicitly about the impact of failures on the overall feasibility of a ...

Elasticity in Service Level Agreements
2013 IEEE International Conference on Systems, Man, and Cybernetics, 2013Elasticity has been identified as one of the key features of delivering IT services over the internet. Major definitions of cloud computing consider elasticity as an essential property of cloud services, and as one of the main reasons to use cloud infrastructures.

Proceedings of the 8th international conference on Electronic commerce The new e-commerce: innovations for conquering current barriers, obstacles and limitations to conducting successful business on the internet - ICEC '06, 2006
This paper describes an ontology based Service Level Agreement formalisation. OWL and SWRL are chosen to express the ontologies. Use of the ontologies, discussing Ontology Adoption, SLA Instance Creation and Validation is given, followed by a breakdown and discussion of the concepts. Ontologies are grouped by generality and diagrammatic representations

Contracting for Professional Service Agreements
Gynecologic Oncology, 1995A review of several professional service agreements (PSA) of managed care organizations which contract with gynecologic oncologists in the Southern California area demonstrates several distinct patterns of practice restrictions and financial benefits which can help guide the physician who is considering signing such an agreement.

Hierarchical aggregation of Service Level Agreements
Data & Knowledge Engineering, 2011{IT-based} Service Economy requires Service Markets to flourish for the trade of services. market does not represent a simple buyer-seller relationship, rather it is the culmination point of a complex chain of stake-holders with a hierarchical integration of value along each point in the chain.

Strategic Web-Service Agreements
2006 IEEE International Conference on Web Services (ICWS'06), 2006This paper addresses issues of strategy in Web-service composition, and inter-site collaboration in general. The results are useful for both human and artificial agents of a site who are responsible for determining Web-service agreements that are most profitable for that site. We discuss three specific questions in this area.
