Production printing workflow is a high-volume and high-speed printing process normally consisting of a set of complex and inter-related tasks namely pre-press, press and post-press procedures. Today many production printing vendors are increasingly offering heterogeneous devices and related software products that autonomously interoperate as a production printing workflow in a digital distributed...
This work describes the architecture of a clinical processes management system aimed to support a process-centered vision of health care practices. At the heart of the system there is a formalism well suited for representation of both processes and related domain knowledge. This language allows the semantic description of clinical processes using ontology and workflow representation formalisms. The...
In this study, we describe our experience in process improvement in a study of one of the foremost manufacturing firms in Turkey. The firm is faced with a large increase in its inventory of returned products. To arrive at solutions to the problem and suggest improvements in the system under consideration, we offer a three-phase methodology which consists of identifying all the sub-problems that lead...
Patient treatment processes require the cooperation of different organizational units and medical disciplines. In such an environment an optimal process support becomes crucial. Though healthcare processes frequently change, and therefore the separation of the flow logic from the application code seems to be promising, workflow management technology has not yet been broadly used in healthcare environments...
Business protocols in n-party interactions often require centralized protocol design but decentralized execution without the intervention of the designing party. In this paper, we tackle the problem for RosettaNet PIPs by creating a BPEL solution. We do so using a three–level approach, based on BPEL, for defining such multi–party protocols: templating for high–level patterns, specialization for particular...
This article describes the method of Mobile Process Landscaping by example of a project in which the service processes of a company from the housing industry were analyzed regarding their mobile potential. This analysis was conducted with the aim to organize these processes more efficiently in order to realize cost savings. Therefore, the method of Mobile Process Landscaping, which is introduced in...
Business collaboration is about coordinating the flow of information among organisations and linking their business processes. It brings great challenge to keep participating organisations as autonomous entities in integrating business processes of these organisations seamlessly. To address this issue, we develop a new perspective on business collaborations with a novel concept called relative workflow,...
Process mining techniques have been receiving great attention in the literature for their ability to automatically support process (re)design. The output of these techniques is a concrete workflow schema that models all the possible execution scenarios registered in the logs, and that can be profitably used to support further-coming enactments. In this paper, we face process mining in a slightly different...
The abilty to continuously revise business practices is essential to organizations aiming at reducing their costs and increasing their revenues. Rapid and continuous changes to business processes result in less control over the executed activities. As a result, the ability of process designers to produce solid, well-validated workflow models is limited. Workflow management systems (WfMSs), serving...
With the advent of Web services and orchestration specifications like BPEL it is possible to define workflows on an Internet-scale. In the health-care domain highly structured and well defined workflows have been specified in standard documents. To reduce the complexity of creating Web service orchestration specifications, we provide a model-driven design approach, consisting of manual and automatic...
Workflow Management Systems (WfMS’s) offer a tremendous potential for organizations. Shorter lead times, less mistakes in work handoffs, and a better insight into process execution are some of the most notable advantages experienced in practice. At the same time, the introduction of these systems on the work floor undoubtedly brings great changes in the way that professionals work. If a WfMS’s work...
We propose a resource management policy that grants or refuses requests for resources based only on the request made and the number of free resources. Computations at runtime are independent of the number of active cases. The policy requires little coordination and is therefore easy to implement in workflow management systems. This policy has been shown to be successful in avoiding deadlocks. In this...
Web service is a promising technology to efficiently integrate disparate software components over various types of systems and to exchange various business artifacts among business organizations. As many web services are nowadays available on Internet, quality of services (QoS) becomes increasingly important to distinguish different service providers. Performance mainly characterizes QoS especially...
This paper deals with Web Workflow Services (W2S) description languages that help organizations to find partners in the context of loose Inter-Organizational Workflow (IOW). Loose IOW refers to occasional cooperation between organizations, free of structural constraints, where the partners involved and their number are not pre-defined. Such a dynamic and heterogeneous context requires the definition...
The increasing dynamics and the continuous changes of business processes raise a challenge to the research and implementation of workflows. The significance of applying formal approaches to the modeling and analysis of workflows has been well recognized and many such approaches have been proposed. However, these approaches require users to master considerable knowledge of the particular formalisms,...
This paper discusses the application of a general process theory – the π-calculus – for describing the behavioral perspective of workflow. The π-calculus is a process algebra that describes mobile systems. Mobile systems are made up of components that communicate and change their structure as a result of communication. The ideas behind mobility, communication and change can also enrich the workflow...
Handling workflow transactional behavior remains a main problem to ensure a correct and reliable execution. It is obvious that the discovery, and the explanation of this behavior, would enable to better understand and control workflow recovery. Unfortunately, previous workflow mining works have concentrated their efforts on control flow aspects. Although powerful, these proposals are found lacking...
Integration of autonomous object-oriented systems requires the integration of object structure and object behavior. Past research in the integration of autonomous object-oriented systems has so far mainly addressed integration of object structure. During our research we have identified business process correspondences and have given proper integration operators. So far these integration operators...
This paper proposes a visualization technique to support the modelling and management of large business process specifications. The technique uses a set of criteria to produce views of the specification that exclude less relevant features. The proposed approach consists of three steps: assessing the relevance of nodes, reducing the specification, and presenting the results. Algorithms and methods...
We present a Petri net semantics for the Business Process Execution Language for Web Services (BPEL). Our semantics covers the standard behaviour of BPEL as well as the exceptional behaviour (e.g. faults, events, compensation). The semantics is implemented as a parser that translates BPEL specifications into the input language of the Petri net model checking tool LoLA. We demonstrate that the semantics...
