- KonferenzbeitragA medical diagnosis system based on Mas technology and neural networks(Business process, services – computing and intelligent service management, 2009) Klüver, Christina; Klüver, Jürgen; Unland, RainerReliable, cost-efficient, and fast medical diagnosis is still a challenge in today's world. This paper presents a medical diagnosis system that combines the advantages of multi-agent system technologies and neural networks in order to realize a highly reliable, adaptive, scalable, flexible, and robust diagnosis system for diseases. The medical diagnosis system consists of a structured alliance of medical experts - realized by agents - that collaborate in order to provide a viable medical diagnosis. Each agent has a certain responsibility. The agents rely on a reactive pattern-based matching process. Their power is substantially augmented by standard kinds of neural networks (interactive neural nets and self organizing maps), which represent the diagnosis capacity of the agents.
- KonferenzbeitragOn application of structural decomposition for process model abstraction(Business process, services – computing and intelligent service management, 2009) Polyvyanyy, Artem; Smirnov, Sergey; Weske, MathiasReal world business process models may consist of hundreds of elements and have sophisticated structure. Although there are tasks where such models are valuable and appreciated, in general complexity has a negative influence on model comprehension and analysis. Thus, means for managing the complexity of process models are needed. One approach is abstraction of business process models-creation of a process model which preserves the main features of the initial elaborate process model, but leaves out insignificant details. In this paper we study the structural aspects of process model abstraction and introduce an abstraction approach based on process structure trees (PST). The developed approach assures that the abstracted process model preserves the ordering constraints of the initial model. It surpasses pattern-based process model abstraction approaches, allowing to handle graph-structured process models of arbitrary structure. We also provide an evaluation of the proposed approach.
- KonferenzbeitragConcept-driven engineering for supporting different views of models(Business process, services – computing and intelligent service management, 2009) Schmidt, PeggyThis paper investigates the the development and evolution of concepts and the management of transformers, which adds semantics to the concepts. We illustrate how concepts, their variants and transformers can be developed via cooperation.
- KonferenzbeitragEvolution of business process models and languages(Business process, services – computing and intelligent service management, 2009) Jablonski, Stefan; Volz, Bernhard; Dornstauder, SebastianThe only constant is change' is an often cited phrase. We regard it as predominant for the area of process based information systems. In this paper we investigate how evolution of process based information systems can be supported by a process modeling framework that easily can be adjusted to changing requirements of an application domain. Our key contribution is the provision of a system infrastructure that supports the adaptation of both process modeling languages and process models to evolving application requirements. Our approach is based on a multi level meta modeling framework.
- KonferenzbeitragA case study on managing slas in composite services with COSMA(Business process, services – computing and intelligent service management, 2009) Ludwig, André; Hering, Thomas; Kluge, Rolf; Franczyk, BogdanCOSMA proposes a novel SLA management approach for composite services. It supports a composite service provider in managing SLAs with providers of atomic services, in managing SLAs with requesters of composite services, and aligning both SLA management activities with each other. On this basis, a composite service provider can control and optimize its composite SLA management activities during the entire SLA lifecycle. This includes, in particular, planning and negotiating SLAs, monitoring and evaluating SLAs. In this paper, a case study on managing SLAs in composite services with the COSMA approach is presented in detail.
- KonferenzbeitragA formal temporal semantics for microsoft project based on Allen's interval algebra(Business process, services – computing and intelligent service management, 2009) Gagné, Denis; Trudel, AndréProcess modeling systems are complex and difficult to compare. A key attribute of any process modeling formalism or tool is time which involves how it handles and represents temporal dependencies and constraints. We are interested in doing a temporal based comparison between process modeling formalisms and tools by first converting them to a common representation. The temporal representation chosen is Allen's interval algebra. In this paper, we explain how to convert a project specified in Microsoft Project to a set of logical formulas. This conversion provides a formal temporal semantics for Microsoft Project.
- KonferenzbeitragDetective information flow analysis for business processes(Business process, services – computing and intelligent service management, 2009) Accorsi, Rafael; Wonnemann, ClausWe report on ongoing work towards a posteriori detection of illegal information flows for business processes, focusing on the challenges involved in doing so. Resembling a forensic investigation, our approach aims at analyzing the audit trails resultant from the execution of the business processes, locating informations flows that violate the (non-functional) requirements stipulated by security policies. The goal is to obtain fine-grained evidence of policy compliance with respect to information flows.
- KonferenzbeitragModelling and solving configuration problems on business processes using a multi-level constraint satisfaction approach(Business process, services – computing and intelligent service management, 2009) Runte, WolfgangIn this paper we present our ideas to apply constraint satisfaction on business processes. We propose a multi-level constraint satisfaction approach to handle different levels of abstraction in business process modelling.
- KonferenzbeitragValidating auction business processes using agent-based simulations(Business process, services – computing and intelligent service management, 2009) Pascalau, Emilian; Giurca, Adrian; Wagner, GerdBusiness Process Modeling and particularly modeling business processes as collaborations is one of the challenges of today enterprise software development. The industry of software development becomes more and more expensive making crucial a correct translation from business idea to implementation to allow for a complete understanding and complete exchange of information between development participants. Particularly, large established software infrastructures are critical with respect to the integration of new components. In this paper, we describe an automated mapping from Single Item English Auction BPMN model to an Agent-Object Relationship simulation towards validation of this business process. The mapping underlines the capabilities of agent-based simulations to execute business processes as well as a number of open questions with respect of BPMN collaboration models.
- KonferenzbeitragDeclarative workflow modeling with UML class diagrams and OCL(Business process, services – computing and intelligent service management, 2009) Brüning, JensThis paper describes an approach of modeling workflows with UML class diagrams and OCL constraints [OCL06] in a declarative way. These are modeled in the UML tool USE [USE08] that can generate object diagrams (snapshots) out of UML class diagrams. USE checks specified OCL constraints against the generated snapshots. With the declarative workflow modeling approach presented here, activity model states are integrated in the object model states. By analyzing these snapshots the model is validated against requirements.
