From process logic to business logic - A cognitive approach to business process management

The unpredictability of business activities means that business process management should provide a way to adapt to change. The traditional workflow approach, based on predefined process logic, offers little support for today's complex and dynamic business environment. Therefore, a cognitive approach is proposed to help manage complex business activities, based on continuous awareness of situations and real-time decisions on activities. In this approach, the business environment is seen as capturing events that occurred and the state of tasks and resources; business logic involving process routing, operational constraints, exception handling and business strategy is used to determine which actions are appropriate for the current situation. By extending process management from process logic to business logic, the methodology offers flexibility, agility and adaptability in complex business process management. © 2005 Elsevier B.V.

Autonomic Protocol-based Coordination in Dynamic Inter-Organizational Workflow

International audienceGiven the maturity of Internet standards, inter-organizational workflow is expected to be deployed in environments that are more dynamic and open than before. This paper addresses Inter Organizational Workflow (IOW) coordination in such a context, mainly investigating autonomic coordination managed at run-time. It is based on the idea that an agent-based approach is suitable to deal with this issue. More precisely, this paper introduces a framework for dynamic IOW in which involved processes are encapsulated into agents, called Process Agents (PA) in order to give them the capability to autonomously decide with whom, when and how to cooperate, and in which involved processes can access protocol components for their coordination needs. Our approach is based on the capability of PAs in playing different coordination protocols in order to take part in new business opportunities. This solution has numerous advantages. First, it provides extendable and reusable coordination components. Then, it supports run-time protocol integration. Finally, it eases openness since it imposes very few constraints

Research on key techniques of flexible workflow based approach to supporting dynamic engineering design process

Error on title page - correct year of award is 2015 not 2013.Engineering design process (EDP) is a highly dynamic and creative process, and the capability in managing an EDP is considered as a major differentiating factor between competing enterprises. The most important prerequisite to establish an engineering design process excellence is a proper management of all the design process activities and the associated information. The most important impact in recent years on the EDP and on the activities of designers has come from computer-based data processing. Workflow, the automation of a business processes in whole or part, is a useful tool for modelling and managing a business process which can be reprensented by a workflow model (computerized process definition). By considering the dynamic characteristics of EDP, an EDP management system must be flexible enough to support the creative and dynamic EDP. After the introduction of engineering design process and its new trend, as well as flexible workflow technology, reviews of both engineering design process and its supporting flexible workflow technology shows that there is a need for a holistic framework to automate and coordinate design activities in the creative and dynamic EDP, and the flexible workflow technology should also be improved comprehensively in flexibility and intelligence in order to support better engineering design management. By introducing the relations between the EDP and flexible workflow, a virtual workflow and an autonomic flexible workflow built upon autonomic computing is investigated, and an innovative engineering design process management framework based on multi-autonomic objects flexible workflow is proposed. For the flexible workflow modelling in the framework, a dynamic instance-based flexible workflow modelling method is proposed for multi-autonomic objects flexible workflow. In order to improve the intelligence of flexible workflow, after examining the principle of flexible workflow intelligence in flexible workflow, a new flexible workflow autonomic object intelligence algorithm based on both extended Mamdani fuzzy reasoning and neural network is proposed, weighted fuzzy reasoning algorithm, as well as precise and fuzzy hybrid knowledge reasoning algorithm is designed; a bionic flexible workflow adaptation algorithm is proposed to improve the intelligence of autonomic object flexible workflow further. According to the characteristic of EDP, such as cross-enterprises and geographical distribution, and in order to realize the flexible execution of distributed flexible workflow engine, a distributed flexible workflow engine architecture based on web service is proposed and a flexible workflow model description method based on extended WSDL (Web Service Description Language) and BPEL4WS (Business Process Execution Language for Web Services) is proposed. A flexible workflow prototype system supporting engineering design process is implemented according to the proposed EDP management framework in Microsoft VS.Net 2005 environment. The framework is demonstrated by the application in an EDP of a MTO company, and it shows that the proposed framework can support the creative and dynamic process in an efficient way. Finally, the strengths and weakness of the framework as well as the prototype system is discussed based on the results of the evaluation, and the proposed areas of future work are given.Engineering design process (EDP) is a highly dynamic and creative process, and the capability in managing an EDP is considered as a major differentiating factor between competing enterprises.

Aide à la conception de workflows personnalisés : application à la prise en charge à domicile

Aujourd'hui, les TIC sont reconnues comme un élément inéluctable pour améliorer les pratiques et les usages du secteur de la santé et particulièrement celui de la PAD. Cependant, malgré tout l'engouement et les avancés accomplies dans ce domaine, un problème de coordination et de continuité des soins personnalisés aux patients subsiste toujours. Un système de gestion de workflow semble approprié pour assurer cette coordination de la PAD. Toutefois, les caractéristiques des processus de la PAD, que nous avons identifié, compliquent la conception de ce workflow. En effet, le processus de la PAD a la particularité d'être un processus, personnalisé pour chaque patient, collaboratif évoluant dans un environnement très dynamique et incertain avec une forte contrainte temporelle. Dans le but d'améliorer la coordination en tenant compte des caractéristiques des processus de la PAD, nous avons proposé une approche de conception d'un workflow personnalisé basé sur les modèles de connaissances et guidée par une approche dirigée par les modèles. Cette approche préconise l'utilisation d'ontologies du domaine de la PAD et du BPMN dans un processus de transformations qui aboutit à la conception d'un workflow personnalisé pour un patient donnée selon son profil. Les travaux développés dans ce mémoire présentent une partie de cette approche qui consiste à construire un processus BPMN personnalisé. Les contributions, que nous y exposons sont : premièrement, la conception d'une ontologie du domaine de la PAD. Cette ontologie inclut : le profil patient (pathologie, entourage, environnement,...), l'aspect organisationnel de la PAD (le rôle de chaque intervenant) et le traitement ou les interventions nécessaires pour chaque pathologie. Deuxièmement une proposition de règles de correspondances entre les termes du domaine de la PAD et du BPMN. Finalement des requêtes permettant la conception d'un processus BPMN personnalisé. Cette approche a été testée sur un cas d'étude de la PAD qui montre son bon fonctionnement.Today, ICT is recognized as a requirement to improve the practices of the health sector and particularly the home care area. However, despite all the advances accomplished in this field, a problem of coordination and continuity of personalized care remains. A workflow management system seems appropriate to ensure the coordination of home care. However, the characteristics of the home care processes complicate the design of the workflow. Indeed, the processes of home care need to be customized for each patient, collaborative, evolving in a very dynamic and uncertain environment with a strong time constraint. In order to improve the coordination taking into account the characteristics of the home care process, we propose an approach to design a custom workflow models based on knowledge and guided by a model driven approach. This approach advocates the use of ontologies in the field of home care and BPMN into a process of transformation that leads to the design of a custom workflow for a given patient according to his profile. The work developed in this thesis are part of this approach is to build a customized BPMN process. Contributions are: first, the design of an ontology for home care. This ontology includes: patient profile (pathology, environment, ...), the organizational aspect of the home care (the role of each actor) and the treatment or interventions necessary for each pathology. Secondly, a proposal of correspondence rules between the terms in the field of home care and BPMN. Finally queries are performed to design a customized BPMN process. This approach has been tested on a significative case study

A platform-independent domain-specific modeling language for multiagent systems

Associated with the increasing acceptance of agent-based computing as a novel software engineering paradigm, recently a lot of research addresses the development of suitable techniques to support the agent-oriented software development. The state-of-the-art in agent-based software development is to (i) design the agent systems basing on an agent-based methodology and (ii) take the resulting design artifact as a base to manually implement the agent system using existing agent-oriented programming languages or general purpose languages like Java. Apart from failures made when manually transform an abstract specification into a concrete implementation, the gap between design and implementation may also result in the divergence of design and implementation. The framework discussed in this dissertation presents a platform-independent domain-specific modeling language for MASs called Dsml4MAS that allows modeling agent systems in a platform-independent and graphical manner. Apart from the abstract design, Dsml4MAS also allows to automatically (i) check the generated design artifacts against a formal semantic specification to guarantee the well-formedness of the design and (ii) translate the abstract specification into a concrete implementation. Taking both together, Dsml4MAS ensures that for any well-formed design, an associated implementation will be generated closing the gap between design and code.Aufgrund wachsender Akzeptanz von Agentensystemen zur Behandlung komplexer Problemstellungen wird der Schwerpunkt auf dem Gebiet der agentenorientierten Softwareentwicklung vor allem auf die Erforschung von geeignetem Entwicklungswerkzeugen gesetzt. Stand der Forschung ist es dabei das Agentendesign mittels einer Agentenmethodologie zu spezifizieren und die resultierenden Artefakte als Grundlage zur manuellen Programmierung zu verwenden. Fehler, die bei dieser manuellen Überführung entstehen, machen insbesondere das abstrakte Design weniger nützlich in Hinsicht auf die Nachhaltigkeit der entwickelten Softwareapplikation. Das in dieser Dissertation diskutierte Rahmenwerk erörtert eine plattformunabhängige domänenspezifische Modellierungssprache für Multiagentensysteme namens Dsml4MAS. Dsml4MAS erlaubt es Agentensysteme auf eine plattformunabhängige und graphische Art und Weise darzustellen. Die Modellierungssprache umfasst (i) eine abstrakte Syntax, die das Vokabular der Sprache definiert, (ii) eine konkrete Syntax, die die graphische Darstellung spezifiziert sowie (iii) eine formale Semantik, die dem Vokabular eine präzise Bedeutung gibt. Dsml4MAS ist Bestandteil einer (semi-automatischen) Methodologie, die es (i) erlaubt die abstrakte Spezifikation schrittweise bis hin zur konkreten Implementierung zu konkretisieren und (ii) die Interoperabilität zu alternativen Softwareparadigmen wie z.B. Dienstorientierte Architekturen zu gewährleisten
