Automatic or assisted workflow composition is a field of intense research for applications to the world wide web or to business process modeling. Workflow composition is traditionally addressed in various ways, generally via theorem proving techniques. The originality of this research stems from the observation that building a composite workflow be...

... composition result is shown in Figure 6. This composed workflow involves synchronization, interleaving, transforma- tions (we used oval boxes to denote transformations) and it should be noted that some execution paths are discarded: indeed, under user rejection, the goal cannot be fulfilled. ...

Supporting enterprise-wide or even cross-organizational business processes is a characteristic challenge for any workflow management system (WfMS). Scalability at the presence of high loads as well as the capability to dynamically modify running workflow (WF) instances (e.g., to cope with exceptional situations) are essential requirements in this c...
Task delegation presents one of the business process security leitmotifs. It defines a mechanism that bridges the gap between workflow and access control systems. Delegation completion and authorisation enforcement are specified under specific constraints so-called events. In this article, we aim to reason about delegation events to model task dele...
This chapter describes a design methodology for business processes and workflows that focuses first on "business artifacts", which represent key (real or conceptual) business entities, including both the business-relevant data about them and their macro-level lifecycles. Individual workflow services (a.k.a. tasks) are then incorporated, by specifyi...

Most of the current workflow-based service composition frameworks and systems require processes to be predefined and services
to be statically-bound, thus lacking necessary flexibility to adapt to frequent changes arising from domain/business/user
rules and the dynamic Internet environment. This paper proposes a service composition framework based on a flexible workflow
method, which enables a part of a process to be created by automatic service composition. In this paper, we propose a semi-automatic
service composition framework which enables a part of a process to be created by automatic service composition. In this framework,
we encapsulate those uncertain, dynamic and variable parts of a process into black-boxes with a set of rules at the modeling
phase. While at the executing phrase, black-boxes are concretized by composing services according to the predefined rules
automatically. This framework has been implemented in DartFlow-a service composition platform for the sharing of the TCM (Tradition
Chinese Medicine) knowledge and services.
