TLDR
This work has developed a complete and minimal set of change operations which support users in modifying the structure of WFs at runtime, while preserving their correctness and consistency.Abstract:
Current workflow management systems (WFMSs) are only applicable in a reliable and secure manner if the business process (BP) to be supported is well structured. As ad hoc deviations from preplanned BPs are rather the norm and form a key part of process flexibility, this limits the applicability of today's workflow (WF) technology significantly. We present a framework for the support of ad hoc structural changes of WFs. Basic to our approach is a conceptual, graph based WF model which has a formal foundation in its syntax and operational semantics. Based upon this model, we have developed a complete and minimal set of change operations which support users in modifying the structure of WFs at runtime, while preserving their correctness and consistency.read more

Manfred Reichert,Peter Dadam +1 more
TL;DR: A formal foundation for the support of dynamic structural changes of running WF instances is presented and a complete and minimal set of change operations (ADEPTflex) that support users in modifying the structure of aRunning WF, while maintaining its (structural) correctness and consistency is defined.

Dynamic and adaptive composition of e-services
Fabio Casati,Ming-Chien Shan +1 more
TL;DR: In this paper, the authors present eFlow, a system that supports the specification, enactment, and management of composite e-services, modeled as processes that are enacted by a service process engine.

Enabling Flexibility in Process-Aware Information Systems
Manfred Reichert,Barbara Weber +1 more
TL;DR: This chapter deals with the flexibility needs of both pre-specified and loosely-specified processes and elicitates requirements for flexible process support in a PAIS.

A comprehensive approach to flexibility in workflow management systems
TL;DR: This paper points out that the modeling process as a main aspect of flexibility by adaption has to be treated as a CSCW scenario, which leads to a structured overall concept for flexibility in workflow management applications.
A Taxonomy of Adaptive Workflow Management
TL;DR: The need for adaptive workflow management is highlighted, various types of workflow adaptation are classified, and potential mechanisms for achieving adaptive workflowmanagement are discussed.

Dynamic change within workflow systems
TL;DR: A Petri net formalism is used to analyze structural change within office procedures and proves that a class of change called “synthetic cut-over change” maintains correctness when downsizing occurs.

TL;DR: The results support the use of a total quality management (TQM) approach of eliminating exceptions for some exceptions, in particular, those caused by computer systems that are poor matches to organizational processes.
