Today’s workflow systems are crossing organizational boundaries and usually involve multiple organizations or partners, and the crossorganization workflow has received much public attention from both the academia and the industry. This way the property analysis as well as system control for a cross-organization workflow is very important. In this paper, we focus on a kind of loosely coupled wor...

Despite so many years’ development, the mainstream of workflow solutions from IT industries has not made ad-hoc workflow-support easy or inexpensive in MIS. Moreover, most of academic approaches tend to make their resulted BPM (Business Process Management) more complex and clumsy since they used to necessitate modeling workflow. To cope well with various ad-hoc or casual requirements on workflo...

Patterns in the domain of workflow management systems(WFMS) have been written. Meszaros and Brown wrote a pattern language for workflow systems[11]. They considered the workflow facility a component of a system and described the process for creating that system. Thus their pattern language falls short of describing workflow facilities managed by an independent WFMS with additional features: tra...

The ABSTRACT FACTORY pattern is a solution often used for isolating clients from the construction of concrete objects. Normally a new concrete factory class is developed for each concrete product family. Therefore new specific construction code has to be written each time a new product family needs to be supported. This approach influences software productivity negatively as it only covers the ...

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...

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...

Forecasting workflow activity durations is of great importance to support satisfactory QoS in workflow systems. Traditionally, a workflow system is often designed to facilitate the process automation in a specific application domain where activities are of the similar nature. Hence, a particular forecasting strategy is employed by a workflow system and applied uniformly to all its workflow acti...

Although reuse is the main goal of SOA, composing existing services to realize different user requirements is still a difficult and time-consuming task. There have been research works on workflow templates and design patterns that facilitates reuse and assist with the process composition task. Nevertheless, existing workflow templates are too specific, whereas design patterns may be too abstrac...

Automatic workflow generation is becoming an active research area for dealing with the dynamics of grid infrastructure, because it has a pervasive impact on system usability, flexibility and robustness. Artificial intelligence technology and explicit knowledge have been exploited in some research for workflow construction or composition. With the increasing use of knowledge, its quality has gro...

We present a new visual and formal approach to the specification of patterns, supporting pattern analysis and pattern-based model completion. The approach is based on graphs, morphisms and operations from category theory and exploits triple graphs to annotate model elements with pattern roles. Novel in our proposal is the possibility of describing (nested) variable submodels, as well as inter-p...
