Abstract. A large genomics project involves a significant number of researchers and technicians performing dozens of tasks, either manual (e.g. performing laboratory experiments), computer assisted (e.g. looking for genes in the GENBANK database), or sometimes performed entirely automatically by the computer (e.g. sequence assembly). It has become apparent that managing such projects poses overwhelming problems and may lead to Disk results of lower or even unacceptable quality, or possibly drastically increased project costs. In this paper, we present Followed a design and an initial implementation of a distributed workflow system created to schedule and support activities in a genomics laboratory. The focus of the activities in the laboratory is the discovery of protein-protein interactions of fungi, specifically Neurospora crassa. We present our approach of developing, adapting and applying workflow technology in the genomics lab and illustrate it using one distinct part of a larger workflow to discover proteinprotein interactions. Novel features of our system include the ability to monitor the quality and timeliness of the results and if necessary, suggesting and incorporating changes to the selected tasks and their scheduling.

The Web Service Choreography Description Language (WSCDL) is a novel specification for describing multiple party collaboration based on web services from a global point of view. WS-CDL is designed to be used in conjunction with the Web Services Business Process Execution Language (WS-BPEL or BPEL), but up to now work on conceptual mappings between both languages is missing. This paper closes this gap by presenting how BPEL process definitions of all parties involved in a choreography can be derived from the global WS-CDL model.

Contemporary business process systems are built to automate routine procedures. Automation demands well-understood domains, repetitive processes, clear organisational roles, an established terminology, and predefined plans. Knowledge work is not like that. Plans for knowledge intensive processes are elaborated and reinterpreted as the work progresses. Interactive process models are created and updated by the project participants to reflect evolving plans. The execution of such models is controlled by users and only partially automated. An interactive process system should - Enable modelling by end users, - Integrate support for ad-hoc and routine work, - Dynamically customise functionality and interfaces, and - Integrate learning and knowledge management in everyday work.

To date, Workflow Management Systems (WfMSs) have been used to support enterprise-wide business processes. With the advent of Internet commerce, business processes increasingly span organizational boundaries. Consequently, workflow technology needs to be extended to support such cross-organizational processes. Three of the most important research issues that arise in developing solutions for cross-organizational business processes are-- process construction, service fulfillment, and conflict resolution. This research primarily addresses the challenge of conflict resolution in cross-organizational processes using exception-handling techniques. Compared to extensive prior work on exception handling in programming languages and distributed system, cross-organizational processes present new challenges. Key challenges are the need to determine responsible party for handling exceptions, a variety of differences between exception handling mechanisms of each WfMS participating in cross-organizational processes, and lack of understanding or knowledge of outsourced or contracted processes. This dissertation represents one of the earliest comprehensive researches on the topic of conflict resolution in cross-organizational processes. We have proposed a detailed exception-handling strategy, have implemented a prototype system, and have conducted experiments using realistic

Abstract. Process–aware information systems (PAIS) must provide sufficient flexibility to their users to support a broad spectrum of application scenarios. As a response to this need adaptive process management systems (PMS) have emerged, supporting both ad-hoc deviations from the predefined process schema and the quick adaptation of the PAIS to business process changes. This newly gained runtime flexibility, however, imposes challenging security issues as the PMS becomes more vulnerable to misuse. Process changes must be restricted to authorized users, but without nullifying the advantages of a flexible system by handling authorizations in a too rigid way. This paper discusses requirements relevant in this context and proposes a comprehensive access control (AC) model with special focus on adaptive PMS. On the one hand, our approach allows the compact definition of user dependent access rights restricting process changes to authorized users only. On the other hand, the definition of process type dependent access rights is supported to only allow for those change commands which are applicable within a particular process context. Respective AC mechanisms will be key ingredients in future adaptive PMS. 1

Decision making in process-aware information systems involves build-time and run-time decisions. At build-time, idealized process models are designed based on the organization’s objectives, infrastructure, context, constraints, etc. At run-time, this idealized view is often broken. In particular, process models generally assume that planned activities happen within a certain period. When such assumptions are not fulfilled, users must make decisions regarding alternative arrangements to achieve the goal of completing the process within its expected timeframe or to minimize tardiness. We refer to the required decisions as escalations. This paper proposes a framework for escalations that draws on established principles from the workflow management field. The paper identifies and classifies a number of escalation mechanisms such as: changing the routing of work, changing the work distribution, or changing the requirements with respect to available data. A case study and a simulation experiment are used to illustrate and evaluate these mechanisms.

This paper presents a classification framework for workflow exception handling in the form of patterns. This framework is independent of specific modelling approaches or technologies and as such provides an objective means of delineating the exception-handling capabilities of specific workflow systems. It is subsequently used to assess the level of exceptions support provided by eight commercial workflow systems and business process modelling and execution languages. On the basis of these investigations, we propose a graphical, tool-independent language for defining exception handling strategies in workflows.

Abstract. Semantic Business Process Management (SBPM) has been proposed as an extension of BPM with Semantic Web and Semantic Web Services (SWS) technologies in order to increase and enhance the level of automation that can be achieved within the BPM life-cycle. In a nutshell, SBPM is based on the extensive and exhaustive conceptualization of the BPM domain so as to support reasoning during business processes modelling, composition, execution, and analysis, leading to important enhancements throughout the life-cycle of business processes. An important step of the BPM life-cycle is the analysis of the processes deployed in companies. This analysis provides feedback about how these processes are actually being executed (like common control-flow paths, performance measures, detection of bottlenecks, alert to approaching deadlines, auditing, etc). The use of semantic information can lead to dramatic enhancements in the state-of-the-art in analysis techniques. In this paper we present an outlook on the opportunities and challenges on semantic business process mining and monitoring, thus paving the way for the implementation of the next generation of BPM analysis tools. 1

Abstract. The success of a company more and more depends on its ability to flexibly and quickly react to changes. Combining process man-agement techniques and conversational case-based reasoning (CCBR) al-lows for flexibly aligning the business processes to new requirements by providing integrated process life cycle support. This includes the adap-tation of business processes to changing needs by allowing deviations from the predefined process model, the memorization and the reuse of these deviations using CCBR, and the derivation of process improve-ments from cases. However, to effectively support users during the whole process life cycle, the quality of the data maintained in the case base (CB) is essential. Low problem solving efficiency of the CCBR system as well as inconsistent or inaccurate cases can limit user acceptance. In this paper we describe fundamental requirements for CB maintenance, which arise when integrating business process management (BPM) and CCBR and elaborate our approach to meeting these requirements. 1

Over the years, medical informatics researchers have studied how to use software technologies to provide decision support for using evidence-based medical procedures. Software professionals have investigated how to support hospital administration, therapy and laboratory workflows. For many of these efforts, managing the exceptions in the workflows is a key issue since the medical workflows must cope with a wide variety of patient medical situations as well as those of the healthcare environments. This paper presents an analysis of past research in managing medical workflow exceptions, and proposes future research that would benefit the medical applications. The paper is focused on three topics: representing, handling and analyzing exceptions. Based upon our analysis, we believe that techniques for verifying exception management models and for handling dynamic exceptions should be useful and possibly essential for developing large scale, practical medical workflow systems.
