Διαχείριση workflow στις εφοδιαστικές αλυσίδες τουριστικών επιχειρήσεωνΚληρόπουλος, Γεώργιος 04 February 2014 (has links)
Οι ροές εργασιών (workflows) αποτελούν έναν από τους πιο σημαντικούς παράγοντες για την σωστή, εύρυθμη και αποδοτική λειτουργία των διαδικασιών που έχουν να φέρουν εις πέρας οι επιχειρήσεις.
Καθώς οι επιχειρήσεις έχουν την τάση να γιγαντώνονται με στόχο την αύξηση των κερδών τους, και με δεδομένο ότι οικονομίες είναι ανοιχτές και δε γνωρίζουν φυσικά σύνορα, τελικά, οδηγούμαστε στην ανάγκη για συνεργασίες μεταξύ των επιχειρήσεων που θα τους επιτρέπουν αφενός να επιτύχουν το βέλτιστο ποιοτικά αποτέλεσμα και αφετέρου με το μικρότερο δυνατό κόστος.
Το μεγάλο μέγεθος των επιχειρήσεων σε συνδυασμό με την ανάγκη για συνεργασίες μεταξύ τους έχουν ως αποτέλεσμα να αυξάνει η πολυπλοκότητα των διαδικασιών και των προβλημάτων που έχουν να επιλύσουν. Αυτό οδηγεί στην ανάγκη να υπάρξει ένας τρόπος διαχείρισης των ροών εργασιών που απαρτίζουν τις διαδικασίες αυτές. Έτσι, ανατπύχθηκαν μηχανές ροών εργασιών (workflow engine) που επιτρέπουν την διαχείριση των ροών με αποδοτικό και βέλτιστο τρόπο.
Στην παρούσα διπλωματική ασχολούμαστε με τη χρήση workflow συστημάτων για την επίλυση του προβλήματος της αποδοτικής διαχείρισης της εφοδιαστικής αλυσίδας (supply chain) στις τουριστικές επιχειρήσεις.
Για την αποδοτική λειτουργία των εφοδιαστικών αλυσίδων απαιτείται η ύπαρξη ενός συστήματος διαχείρισής τους, με σκοπό να οργανώνει και να συγχρονίζει τις διαφορετικές οντότητες που παίρνουν μέρος σε όλα τα βήματα μιας εφοδιαστικής αλυσίδας. Έτσι, έχουν αναπτυχθεί τέτοια συστήματα διαχείρισης, όπου με την βοήθεια των υπολογιστών μοντελοποιούν και καταγράφουν όλα τα βήματα της εφοδιαστικής αλυσίδας, κάνοντας έτσι αποδοτική την λειτουργία της.
Αφού παρουσιαστούν τα πιο δημοφιλή open source workflow engines, στη συνέχεια υλοποιούμε την δική μας workflow engine που επιλύει το πρόβλημα της διαχείρισης των εφοδιαστικών αλυσίδων σε τουριστικές επιχειρήσεις. Πιο συγκεκριμένα, αναπτύχθηκε ένα basic custom workflow engine προσαρμοσμένο στις ανάγκες των τουριστικών επιχειρήσεων όσον αφορά τη διαδικασία διαχείρισης της εφοδιαστικής τους αλυσίδας στο κομμάτι από την δημιουργία μιας νέας παραγγελίας από προϊόντα και πρώτες ύλες μέχρι το τελικό βήμα της αποδοχής της παραγγελίας από τους υπεύθυνους των τουριστικών επιχειρήσεων. Η εφαρμογή που υλοποιήθηκε είναι web based application. Οι web εφαρμογές παρουσιάζουν αρκετά πλεονεκτήματα έναντι των παραδοσιακών desktop εφαρμογών, τα οποία και παρουσιάζονται στη διπλωματική αυτή. / --

Modélisation de la variabilité des flux de production en fabrication microélectronique / Workflow variability modeling in microelectronic manufacturingDequeant, Kean 09 November 2017 (has links)
Dans un contexte où l’industrie du semi-conducteur explore de nouvelles voies avec la diversification des produits et le paradigme de « More than Moore », les délais de livraison et la précision de livraison sont des éléments clés pour la compétitivité d’entreprises de semi-conducteur et l’industrie 4.0 en général. Les systèmes de production sont cependant sujets à de la « variabilité », qui crée des embouteillages dans la production de manière incontrôlée et imprévisible. Cette thèse CIFRE (partenariat entre le laboratoire GSCOP et STMicroelectronics) s’attaque à ce problème de la variabilité dans la fabrication en environnement complexe. La première partie de cette thèse offre une étude approfondie de la variabilité: nous mettons d’abord en avant les conséquences de la variabilité pour mieux la définir, puis nous clarifions que la variabilité concerne les flux de production en introduisant la notion de variabilité des flux de production et en apportant des éléments de mesure associés, et nous clôturons cette première partie par l’étude des sources de variabilité à travers une étude bibliographique et des exemples industriels. La seconde partie est dédiée à l’intégration de la variabilité dans les outils de gestion de production: nous montrons comment une partie des conséquences peut être mesurée et intégrée aux projections d’encours pour améliorer le contrôle et la prévisibilité de la production, proposons un nouvel outil ((the WIP Concurrent) pour mesurer plus précisément les performances des systèmes en environnement complexe, et mettons en avant des effets de dépendances prépondérants sur la variabilité des flux de production et pourtant jamais pris en compte dans les modèles. La troisième et dernière partie de la thèse couvre les perspectives de réduction de la variabilité : en se basant sur les éléments présentés dans la thèse, nous proposons un plan pour réduire la variabilité des flux de production sur le court terme, et une direction pour la recherche à moyen et long terme. / In the context of Industry 4.0 and the More than Moore’s paradigm, delivery precision and short cycle times are essential to the competitiveness of High Mix Low Volume semiconductor manufacturing and future industries in general. So called “variability” however creates uncontrolled and unpredictable “traffic-jams” in manufacturing systems, increasing cycle times and decreasing the systems’ tractability. This research, a CIFRE PhD between the GSCOP laboratory and STMicroelectronics, addresses this issue of variability in complex manufacturing environment. We first conducted, in the first part of the manuscript, an in-depth study of “variability”: we approached the notion through its consequences in manufacturing systems, clarified that the variability was about the workflow, introducing the notion of workflow variability and measures that come with it, and identified the main sources of variability through a literature review and real-world examples. We focused in the second part of this manuscript on the integration of workflow variability in production management tools: We showed how integrating the stable consequences of workflow variability can improve WIP projections in complex systems and increase the control on such systems, proposed a new tool (the Concurrent WIP) to better measure the performances of systems subject to high workflow variability, and showed that complex “dependency” mechanisms play a key role in workflow variability yet are not integrated in any model. Finally, the third and last part of the manuscript organized perspectives for variability reduction: based on the work of this manuscript, we showed a framework for variability reduction on the short term, and proposed a direction for medium and long-term research.

« Prendre soin » du travail : dispositifs de gestion du flux et régulations émergentes en radiothérapie / "Taking care" of Work : Workflow Management Devices and Emerging Regulations in RadiotherapyMunoz, Maria Isabel 21 June 2016 (has links)
Cette recherche en ergonomie, aborde l’étude du travail au travers de la notion du « prendre soin ». Elle porte sur le processus de production coopérative du soin et plus particulièrement sur le soutien de la gestion du flux de travail, ou workflow, dans la production du soin radiothérapeutique. Cette recherche s’est déroulée dans le cadre d’un projet d’innovation industrielle pour la conception d’un outil informatique de workflow en radiothérapie. Ce traitement contre le cancer est conçu par un collectif transverse dans un processus comprenant plusieurs étapes qui présente des exigences de coopération. L’objectif de cette thèse est d’apporter des éléments de compréhension sur le « prendre soin » du travail à partir de l’étude de la gestion du flux de travail. Des observations systématiques dans quatre centres de radiothérapie français permettent de modéliser des dispositifs de gestion de flux de travail (DGF) en situation nominale. Dans un des centres, 32 entretiens portant sur la reconstitution du DGF local à partir de traces de l’activité, permettent de comprendre la gestion du flux de travail en situation d’exception (incidentelle ou de variabilité). Les résultats mettent en évidence une « invention organisationnelle » issue de la « mise en main » et la mobilisation d’un environnement physique sémiotisé dans le soutien de la gestion collective du flux de travail. Par la mobilisation du DGF en situation nominale les professionnels visent la production de traitements sûrs et efficaces ainsi que le « prendre soin » du travail d’articulation. En situation d’exception, des pratiques de régulation émergente permettent de produire des traitements sûrs et efficaces et de « prendre soin » du patient, du travail de l’autre et de son propre travail.Les retombées de notre travail portent sur le développement et l’outillage du processus du flux de travail et la conceptualisation de la qualité en milieu du soin. Ainsi, la qualité du processus de production du soin est composée des dimensions d’efficacité et de sécurité du traitement (cure) ainsi que de la dimension du « prendre soin » (ou care) des patients, du travail coopératif et plus largement, du travail collectif. Enfin, cette recherche permet de penser les dimensions du « prendre soin » comme partie intégrante de la qualité du travail individuel et collectif. / This research in ergonomics addresses the "taking care" dimension of work. It deals with the cooperative processes involved in healthcare production, and more particularly with supporting the workflow in radiotherapy. The research takes place within an industrial innovation project aiming at developing a workflow software. Radiotherapy is a treatment against cancer by the administration of ionizing radiation. This type of treatment is produced by a transverse collective in a multi-step process with cooperation requirements. The objective of this thesis is to better understand the “taking care” dimension of work by analyzing workflow management. Systematic observations in four French radiotherapy services have allowed the modelling of Workflow Management Devices (WMD) in nominal situations. In a radiotherapy center, 32 interviews were conducted with professionals, by using a restitution of the local WMD composed by traces of activity. This helped to understand the professionals’ activity in exceptional situations (non nominal). The results highlight a “tailored”, “semioticized” physical environment, that supports the collective workflow management in order to ensure a safe and efficient treatment and to “take care” of the articulation work. This environment supports the normative model of the radiotherapy process. Furthermore, in exceptional situations, emerging regulation strategies help to produce safe and efficient treatments and to take care of the patient, the work of colleagues and of one’s own work.The impact of our work concerns the development of workflow processes and tools and the conceptualization of quality in healthcare. Healthcare quality integrates the safety and effectiveness of treatments (cure) as well as the “taking care”, not only of patients, but of cooperative and collective work. Finally, this research helps in conceptualizing that “taking care” of cooperative work is to be considered as an additional dimension of the quality of individual and collective work.

Uma abordagem incremental para mineração de processos de negócio / Incremental approach to business process miningKalsing, André Cristiano January 2012 (has links)
Até os dias de hoje, diversos algoritmos de mineração de modelos de processos já foram propostos para extrair conhecimento a partir de logs de eventos. O conhecimento que tais algoritmos são capazes de obter incluem modelos de processos de negócio, assim como aspectos da estrutura organizacional, como atores e papéis. A mineração de processos pode se beneficiar de uma estratégia incremental, especialmente quando as informações sobre um ou mais processos de negócio presentes no código fonte de um sistema de informação são logicamente complexas (diversas ramificações e atividades paralelas e/ou alternativas). Neste cenário, são necessárias muitas execuções da aplicação para a coleta de um grande conjunto de dados no arquivo de log, a fim de que o algoritmo de mineração possa descobrir e apresentar o processo de negócio completo. Outra situação que torna necessária a mineração incremental é a constante evolução dos processos de negócio, ocasionada geralmente por alterações nas regras de negócio de uma ou mais aplicações. Neste caso, o log pode apresentar novos fluxos de atividades, ou fluxos alterados ou simplesmente fluxos que não são mais executados. Estas mudanças devem ser refletidas no modelo do processo a fim de garantir a sincronização entre a aplicação (processo executado) e o modelo. A mineração incremental de processos pode ainda ser útil quando se faz necessária a extração gradual de um modelo de processo completo, extraindo modelos parciais (fragmentos de processo com início e fim) em um primeiro passo e integrando conhecimento adicional ao modelo em etapas até a obtenção do modelo completo. Contudo, os algoritmos atuais de mineração incremental de processos não apresentam total efetividade quanto aos aspectos acima citados, apresentando algumas limitações. Dentre elas podemos citar a não remoção de elementos obsoletos do modelo de processo descoberto, gerados após a atualização do processo executado, e também a descoberta de informações da estrutura organizacional associada ao processo como, por exemplo, os atores que executam as atividades. Este trabalho propõe um algoritmo incremental para a mineração de processos de negócio a partir de logs de execução. Ele permite a atualização completa de um modelo existente, bem como o incremento de um modelo de processo na medida em que novas instâncias são adicionadas ao log. Desta forma, podemos manter ambos, modelo de processo e o processo executado sincronizados, além de diminuirmos o tempo total de processamento uma vez que apenas novas instâncias de processo devem ser consideradas. Por fim, com este algoritmo é possível extrair modelos com acurácia igual ou superior aqueles que podem ser extraídos pelos algoritmos incrementais atuais. / Even today, several process mining algorithms have been proposed to extract knowledge from event logs of applications. The knowledge that such algorithms are able to discovery includes business process models, business rules, as well as aspects of organizational structure, such actors and roles of processes. These process mining algorithms can be divided into two: non-incremental and incremental. The mining process can benefit from an incremental strategy, especially when information about the process structure available in the system source code is logically complex (several branches and parallel activities). In this scenario, its necessary several executions of the application, to collect a large set of log data, so that the mining algorithm can discover and present the complete business process. Another use case where incremental mining is usefull is during the changing structure of the process, caused by the change in the business logic of an application. In this case, the log may provide new traces of activities, modified traces or simply traces that are no longer running. These changes must be reflected in the process model being generated to ensure synchronization between the application and model. The incremental process mining can also be useful when it is necessary to extract a complete process model in a gradual way, extracting partial models (process fragments with begin and end) in a first step and integrating additional knowledge to the model in stages to obtain the complete model. However, existing incremental process mining algorithms are not effective to all aspects mentioned above. All of them have limitations with respect to certain aspects of incremental mining, such as deletion of elements in the process model (process model update). Additionally, most of them do not extract all the information present in the structure of the process, such as the actors who perform the activities. This paper proposes an incremental process mining algorithm from execution logs of information systems. The new algorithm allows the full update (adding and removing elements) of an existing model, as well as the increment of a process model as new records are added to the log. Thus, we can keep process models and process execution syncronized, while reducting the total processing time, since only new process instances must be processed. Finally, are expected the extraction of process models with similar or higher accuracy compared to current incremental mining algorithms.

Modelagem de sistemas de informação na internet como sistemas de workflow sobre documentos estruturados / Internet information systems modelling how workflow systems witch structured documentsWeinfurter, Maristela Regina January 2001 (has links)
A construção de aplicações Web é algo complexo, pois envolve requisitos não previstos na modelagem de sistemas convencionais. O ambiente Web agrega características como: navegabilidade, estruturação de hiperdocumentos, workflow, acessibilidade, escalabilidade, usabilidade, compatibilidade, interoperabilidade, segurança, aspectos culturais, entre outros. O presente trabalho propõe que a modelagem de sistemas de informação na Internet incorpore características existentes na modelagem de sistemas de gerência de workflow manipulando hiperdocumentos. A notação utilizada é uma extensão à notação da UML (Unified Modeling Language). Esta consiste de novos estereótipos que modelem hiperdocumentos e sistemas de gerência de workflow em sistemas de informação na Web. A extensão propõe a utilização de diagrama de atividades estendido para modelar o workflow de atividades, o qual manipula hiperdocumentos envolvidos no domínio de uma aplicação Web. Os hiperdocumentos são modelados através de diagramas de estrutura de documentos, que são derivados do diagrama de classes da UML. A navegabilidade dos documentos é desenhada através dos diagramas de contexto de navegação e restrições de acessos de em casos de uso. Finalizando a modelagem, o diagrama de estrutura de documentos recebe todas as características dinâmicas, estáticas e de ligação que são modeladas através dos diagramas estendidos bem como pelos diagramas comportamentais e estáticos da UML. A modelagem segue a notação da UML, sendo sugerido que numa primeira etapa, modele-se os hiperdocumentos e sua estruturação preliminar. Na seqüência, com auxílio do diagrama de casos de uso, modela-se o fluxo de atividades através do diagrama de atividades estendido. Após este levantamento, tanto de documentos quanto de atividades envolvidas no domínio da aplicação, modela-se o contexto de navegação e restrições em acessos de casos de uso, que evidenciam os componentes de ligação necessários à navegabilidade entre os hiperdocumentos. Através da extensão proposta à notação da UML, que considera aspectos de workflow, estruturação de hiperdocumentos e navegabilidade, as fases de projeto e implementação de software, sofrem menos alterações e interferências de adaptação às características das ferramentas de implementação para este novo ambiente. / Implementation of Web applications is a complex task since it involves requirements not previously accounted for modelling conventional systems. The Web environment possesses characteristics such as ease of navigation, hyperdocument structuring, workflow, access and scale facilities, usability, compatibility and interoperability, safety and cultural aspects amongst others. The present work proposes that modelling of information systems in the Internet incorporate the existing characteristics of modelling workflow management systems to handle structured hyperdocuments. The notation used is an extension to the UML (Unified Modelling Language) notation, which consists in new stereotypes for hyperdocument modelling and incorporated workflow in information systems. The extension proposes use of the extended diagram of activities to model the activity workflow which will handle the hyperdocuments involved in the domain of a Web application. The hyperdocuments will be modelled using diagrams of document structure, which are derived from the UML class diagrams. The navigation of documents is designed using the surfing context diagrams and access restriction associated to the use cases. Modelling is finalised by adding to the document structure all the dynamic, static and link characteristics which are modelled though the extended diagrams, as far as the behaviour and static diagrams of the UML. The modelling procedure follows the UML notation, being suggested that, in a first step, the modelling of a preliminary document structuring. In sequence, using the diagram of use cases, the activity flow is modelled by using the extended diagram of activities. After the research procedures associated to documents and activities related to the application domain, the surfing contexts and access restrictions of the use cases are modelled to evince the link components necessary to the navigation amongst documents. The use of the proposed extension to the UML notation, which accounts for workflow aspects, hyperdocument structuring and its navigation, will lead to less changes of the project development and software implementation to account for the characteristics of the implementation tools for this new environment.
