Recently, a variety of workflow patterns has been proposed focusing on specific aspects like control flow, data flow, and resource assignments. Though these patterns are relevant for implementing Business Process Modeling (BPM) tools and for evaluating the expressiveness of BPM languages, they do not contribute to reduce redundant specifications of recurrent business functions when modeling bus...

Selecting an appropriate process modeling language forms an important task for organizations engaging in business process management initiatives. A plethora of process modeling languages has been developed over the last decades, leading to a need for rigorous theory to assist in the evaluation and comparison of the capabilities of these languages. While substantial academic progress in the area...

Engineering workflow applications are becoming more and more complex, involving numerous interacting business objects within considerable processes. Analysing the interaction structure of those complex applications will enable them to be well understood, controlled, and redesigned. Our contribution to workflow mining is a statistical technique to discover workflow patterns from event-based log....

Product development process (PDP) is one of the most important business processes for enterprises but it has difficulty in workflow management because of the uncertain and dynamic characteristics. Thus, even though there have been many workflow modeling and management methods, they have limitations to deal with the special characteristics of PDP. We define PWF-nets based on timed colored Petri ...

Application-level multi-tenancy is an increasingly prominent architectural pattern in Software-as-a-Service (SaaS) applications that enables multiple tenants (customers) to share common application functionality and resources among each other. This has the disadvantage that multi-tenant applications are often limited in terms of customizability: one application should fit the needs of all custo...

Analysing the interaction structure of those complex applications will enable them to be well understood, controlled, and redesigned. Our contribution to workflow patterns analysis is a statistical technique to discover workflow patterns from event-...

This paper identifies a set of workflow patterns necessary to support community-oriented localisation. Workflow pattern discovery is based on use case analysis of five community translation tools, and modelled using the Yet Another Workflow Language (YAWL) notation. An analysis is presented of the support for these baseline patterns in two mainstream enterprise-oriented Translation Management S...

This paper addresses the QoS-aware service selection problem considering complex workflow patterns. More specifically, it focuses on the complexity issues of the problem. The NP-hardness of the problem, under various settings, has been open for many years and has never been addressed thoroughly. We study the problem complexity depending on the workflow structure, the number of workflow tasks, t...

The Business Process Execution Language for Web Services (BPEL) has emerged as a standard for specifying and executing processes. It is supported by vendors such as IBM and Microsoft and positioned as the “process language of the Internet”. This paper provides a critical analysis of BPEL based on the so-called workflow patterns. It also discusses the need for languages like BPEL. Finally, the p...

Introduction: In clinical practices, the use of information technology, especially computerized provider order entry (CPOE) systems, has been found to be an effective strategy to improve patient care. This study aimed to compare physicians’ and nurses’ views about the impact of CPOE on their workflow. Methods: This case study was conducted in 2012. The potential participants included all physic...
