Workflow Management Systems have been increasingly used in companies to automate organizational processes. To allow the integration of those systems, the Workflow Management Coalition (WfMC) defined the Workflow Reference Model. The Object Management Group (OMG), looking for the standardization of workflow management systems in the context of its objectoriented architecture, had also defined a ...

Scientific research products are the result of long-term collaborations between teams. Scientific workflows are capable of helping scientists in many ways including collecting information about how research was conducted (e.g., scientific workflow tools often collect and manage information about datasets used and data transformations). However, knowledge about why data was collected is rarely d...

banking and financial services are important parts of the service industry. quality of service in the banking industry has a close relationship with customer satisfaction service system. banks could create competitive advantage by increasing customer satisfaction and reduce costs in today's competitive environment. this paper presents a decision-making model to obtain optimum tasks assigne...

Though the activities of business organizations in the field of workflow management are facing an enormous growth, a methodical solution for an essential problem occurring in many workflow projects is still lacking: the identification of those processes that can be supported by workflow applications in a profitable way. In this paper we present a structured framework, which can serve as a guide...

This paper introduces a novel approach for flexible workflow management by applying constraint satisfaction problem solving. This enables us to support workflow deviations at runtime, react to upcoming events or unpredictable circumstances, but still support the user through worklist suggestions. The developed workflow engine is completely based on declarative workflow representations, whereas ...

In scientific workflow systems, it is critical to ensure the timely completion of scientific workflows. Therefore, temporal constraints, as a type of QoS (Quality of Service) specification, are usually required to be managed in scientific workflow systems. Specifically, temporal constraint management includes two basic tasks: setting temporal constrains at workflow build time and updating tempo...

This paper presents market-based workflow management, a novel approach to workflow specification and execution which regards activities contained in a workflow as goods traded on an electronic market. Information about expected cost and execution time is considered for activity specifications, and is used at runtime to execute workflows such that actual cost and execution times are balanced and...

Workflow Management (WfM) is evolving quickly and expolited increasingly by businesses in a variety of industries. Its primary characteristic is the automation of processes involving combinations of human and machinebased activities, particularly those involving interaction with IT applications and tools. Although its most prevalent use is within the office environment in staff intensive operat...

in this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. the engines are assumed to be implemented as composite web services. current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. the difficulty is to rollback the execution state of the workflo...

Researchers typically need to combine Bioinformatics processes to perform larger, more complex tasks, expressed as workflows. However, there is a strong indication from users that running complex workflows is an addition burden that must be alleviated. Motivated by this observation, this paper first introduces an ontology that defines classes and instances of Bioinformatics projects, processes,...
