In this paper we describe the design and implementation of workflow management applications on top of Notes Release 4. We elaborate on various design issues for Notes workflow applications and introduce Notes Release 4’s native workflow concepts like agents, events, macros, LotusScript, OLE2 capabilities, and doclinks, which make Notes a powerful workflow tool. The idea of the paper is the use ...

A workflow defines flow of information and control in a process. Most software solutions for workflow management systems do not model the real world scenario perfectly. Moreover, changes in the workflow result in many modifications to the application. The Mobile Agent paradigm not only provides a richer model for workflow systems that better resembles the real world scenario but can also be use...

Petri nets are often used to model and analyze workflows. Many workflow languages have been mapped onto Petri nets in order to provide formal semantics or to verify correctness properties. Typically, the so-called Workflow nets are used to model and analyze workflows and variants of the classical soundness property are used as a correctness notion. Since many workflow languages have cancelation...

Traditionally, workflow management systems (WfMS) are heavy monolithic software with vendor specific protocol. The lack of standardisation become a real problem for interoperability. To face this problem, vendors, users and researchers founded the Workflow Management Coalition (WfMC) and defined the workflow reference model [3]. Based on this work, the OMG designed the Workflow Management Facil...

Component-based development is a promising way to promote the productivity of large workflow systems development. This paper proposes a component-based workflow systems development approach by investigating the following notions, mechanisms, and methods: workflow component, workflow component composition, reuse–association relationship between workflow components, and workflow component reposit...

Despite the great effort devoted to the development of Workflow models and Workflow Management Systems during the last decade, a strong foundation about workflow development is still to come. Assuming that a workflow is a complex software product, in this paper we argue that the principles and techniques of software development — in particular, methodological concerns— can help in the developme...

A very important topic in the effort of deploying workflow applications in grid environments is finding a means to describe the complex application structures that is simple for users yet expressive enough to provide the workflow scheduler with the information needed to make (good) scheduling decisions. A workflow description language defines syntax and semantics for specifying workflow tasks a...

In order to support efficient workflow design, recent commercial workflow systems are providing templates of common business processes. These templates, called cases, can be modified individually or collectively into a new workflow to meet the business specification. However, little research has been done on how to manage workflow models, including issues such as model storage, model retrieval,...

The increasing complexity of business processes in the era of e-business has heightened the need for workflow verification tools. However, workflow verification remains an open and challenging research area. As an indication, most of commercial workflow management systems do not yet provide workflow designers with formal workflow verification tools. We propose a logic-based verification method ...

The workflow and its supporting systems are integral to computational science. Tailored to loosely coupled, and largely coarse-grained tasks, the workflow replaces the script as a way to automate the multiple steps of a large scale model. Workflow reuse has been at the subworkflow level but this restricts, over the long run, a workflow to running on the system on which it was developed. A scien...
