Web Services Supply Chains: A Literature Review
For researchers in service-oriented computing, this paper highlights underexplored areas and provides a conceptual foundation, but it is a literature review with no empirical results.
This review paper identifies gaps in web services supply chain research, noting less work compared to e-commerce and product-oriented supply chains, and proposes a conceptual model to address quality-driven optimization and collective QoS perspectives.
The aim of this review paper is to bring into light a potential area i.e., web services supply chains for research by analyzing the existing state of art in this. It is observed from the review process that there seems to be much less work done in the area of web service supply chains as compared to e-commerce and product oriented service supply chains. The service quality assurance models, end to end Quality of Service (QoS) models, attempts made to QoS attributes are also found to be from individual perspectives of participating entities in a service process rather than a collective perspective considering individual QoS attributes rather than multiple QoS attributes. In light of these gaps we highlight the comparison between product oriented and pure online/ web service supply chains, a need for quality driven optimization in the web services supply chains, perceived complexities in the existing work and propose a conceptual model.
