An Object-oriented Workflow Modeling Schema Using Dataflow Analysis for Collaborative E-governance Platform
In the initial stage of transforming from government to governance for developing countries, collaborative e-governance platforms should be urgently established in different contexts. Though some platforms have been previously applied to various fields, researches on common basic functions analysis and across-organization business process modeling based on a suitable workflow modeling method for the platforms design and development are insufficient. Based on an explorative analysis of platform functions and their patterns, we propose a schema for e-governance platforms modeling according to an extended method of object-oriented workflow modeling using dataflow analysis. It covers a two-step process of top-level platform workflow modeling and function objection workflow modeling. In addition, a citizen appeal processing platform is taken as an example to illustrate the utility of the schema. The schema facilitates the contextualized collaborative e-governance platforms development with an operable method and reusable function workflow models
Towards an Intelligent Workflow Designer based on the Reuse of Workflow Patterns
In order to perform process-aware information systems we need sophisticated methods and concepts for designing and modeling processes. Recently, research on workflow patterns has emerged in order to increase the reuse of recurring workflow structures. However, current workflow modeling tools do not provide functionalities that enable users to define, query, and reuse workflow patterns properly. In this paper we gather a suite for both process modeling and normalization based on workflow patterns reuse. This suite must be used in the extension of some workflow design tool. The suite comprises components for the design of processes
from both legacy systems and process modeling

KWM: Knowledge-based Workflow Model for agile organization
The workflow management system (WFMS) in an agile organization should be highly adaptable to the frequent organizational changes. To increase the adaptability of contemporary WFMSs, a mechanism for managing changes within the organizational structure and changes in business rules needs to be reinforced. In this paper, a knowledge-based approach for workflow modeling is proposed, in which a workflow is defined as a set of business rules. Knowledge on the organizational structure and special workflow, such as role/actor mappings and complex routing rules, can be explicitly modeled in KWM (Knowledge-based Workflow Model).
Using knowledge representation scheme and dependency management facility, a change propagation mechanism is provided to adapt to the frequent changes in the organizational structure, business rules, and procedures
Methodological Considerations for Time Modeling inWorkflows
This paper offers a critical analysis of the popular control-flow-oriented workflow modeling paradigm and argues that time is not just an additional property specified on the top of control flows as it is commonly done in commercial and research workflow models. It also explains why this way of time modeling can easily lead to an inability to properly specify temporal constraints and verify their consistency. The paper proposes a two-level workflow modeling where the control-flow level is used for modeling of control flows, monitoring of workflow execution and reasoning about the order of tasks while the operational level is used for more precise time modelling and verification of temporal constraints
Modeling Workflow Processes Based on Tasks and Transactions: A Case Study of the UPM Graduate School Office
Workflow binds, integrates the people, the processes, and
the organisation into a value chain. Workflow modeling is used to
redesign work processes to increase the efficiency and productivity
of work. Workflow is said to be the technological cousin to
Business Process Reengineering. Workflow carries the promise of
integrating office work, resulting in short delay times, improved
customer services and better knowledge of logistics parameters of
office work.
Workflow systems support business systems by maintaining
the logical sequence of transitions between tasks in a work
process, making sure that all related tasks or a process are completed. Tasks and transactions form an integral part of a
workflow management system.
However, workflow modeling is a relatively new field. Many
organisations intending to conduct business process re-engineering
are finding it difficult to obtain frameworks to model their
workflows. This study presents the development of a framework
for these organisations to model workflow processes. Old
workflow processes are studied from a selected organisation and a
new workflow model is designed. The performance improvements
of the new workflow model over the old workflow model are then
quantified. From here, a framework for workflow modeling is
produced for future reference.
Important concepts and issues that need attention when
modeling workflows, are discussed. These issues can be used to
overcome setbacks faced by many organisations while modeling
their workflows, such as identifying problems in the workflow and
redesigning a workflow model that will increase productivity.
From this study, it is revealed that redesigning workflows
require that each process be looked into carefully for its flaws and
problems, to look for measures to improve the processes, and to
redesign these workflow processes with attention given to issues,such as allowing the workflow model to be open, reusable,
portable and scalable. With these issues in reference, workflow
modeling can then be successfully implemented, for the
re-engineering of any organisation
An Evaluation of Inter-Organizational Workflow Modelling Formalisms
This paper evaluates the dynamic aspects of the UML in the context of inter-organizational workflows. Two evaluation methodologies are used. The first one is ontological and is based on the BWW (Bunge-Wand-Weber) models. The second validation is based on prototyping and consists in the development of a workflow management system in the aerospace industry. Both convergent and divergent results are found from the two validations. Possible enhancements to the UML formalism are suggested from the convergent results. On the other hand, the divergent results suggest the need for a contextual specification in the BWW models. Ce travail consiste en une évaluation des aspects dynamiques du language UML dans un contexte de workflow inter-organisationnel. Le choix du language par rapport à d'autres est motivé par sa richesse grammaticale lui offrant une très bonne adaptation à ce contexte. L'évaluation se fait par une validation ontologique basée sur les modèles BWW (Bunge-Wand-Weber) et par la réalisation d'un prototype de système de gestion de workflows inter-organisationnels. À partir des résultats convergents obtenus des deux différentes analyses, des améliorations au formalisme UML sont suggérées. D'un autre coté, les analyses divergentes suggèrent une possibilité de spécifier les modèles BWW à des contextes plus particuliers tels que ceux des workflows et permettent également de suggérer d'autres améliorations possibles au langage.Ontology, Conceptual study, Prototype Validation, UML, IS development methods and tools., Ontologie, étude conceptuelle, validation du prototype, UML, méthodes et outils de développement IS
