Massive parallel business workflows running in the cloud are prone to temporal violations (namely intermediate runtime delays) due to various reasons such as service performance fluctuation and resource conflicts. To deliver satisfactory on-time completion, cloud workflow temporal verification is employed to accurately detect time delays of workflow activities and timely handle temporal violations...
Temporal violations often take place during the running of large batch of parallel business cloud workflow, which have a serious impact on the on-time completion of massive concurrent user requests. Existing studies have shown that local temporal violations (namely the delays of workflow activities) occurring during cloud workflow execution are the fundamental causes for failed on-time completion...
Community Cloud (CC) emerges as a rapid developing paradigm in many fields such as research and education. Business process (BP) that facilitates the organization cooperation and resource sharing plays an important role in CC. The execution efficiency of BP has a pivotal impact on the quality of community cloud services. CC applications often have high demands on BP execution efficiency, which is...
In recent years, cloud computing is establishing itself as the latest high-performance and high-throughput computing paradigm, and thus doing business in the cloud is becoming a reality. However, due to the dynamic nature of the cloud environment, the on-time completion of time-constrained business workflows is a big challenge. Workflow temporal verification as the major approach to monitor and control...
Nowadays, most business processes are running in a parallel, distributed and time-constrained manner. How to guarantee their on-time completion is a challenging issue. In the past few years, temporal checkpoint selection which selects a subset of workflow activities for verification of temporal consistency has been proved to be very successful in monitoring single, complex and large size scientific...
In today's highly competitive situation, business model innovation is critical for the survival and development of an enterprise. Domestic and foreign scholars who use several of methods in the research on business model innovation have achieved great accomplishments, but overall they are still relatively fragmented. Aiming to avoid detours in innovation process and increase innovation efficiency,...
With the development of web service applications, how to realize on-demand services selection according to user's personal requirements is a hot research work in modern times. WS-CDL (Web Services Choreography Description Language) is a W3C candidate recommendation for the description of peer-to-peer collaborations for the participants in web services interaction. However, the goal of the service...
