Providing pan-european e-government services with the use of semantic web services technologies : A Generic Process model
Lecture Notes in Computer Science, 2005Co-Authors: Vassilios Peristeras, Konstantinos TarabanisAbstract:In this paper, we present our experience of using the Governance Enterprise Architecture (GEA) for designing Pan-European eGovemment Services (PEGS) implemented by Semantic Web Service (SWS) technologies. GEA consists of a set of models and serves as a top-level Generic Enterprise Architecture for the overall governance domain. Here we use one of the GEA models (the Generic Process model for service execution) as a blueprint, and instantiate it in the specific business (cross-boarder new company establishment) and technology setting (SWS). Although based on a specific business case, the paper generalizes and focuses on the case-independent, core aspects of PEGS provision with SWS to present a reusable model. For presenting the model, we employ a use case-based, narrative description.

flexible workflow management systems an approach based on Generic Process models
Database and Expert Systems Applications, 1999Co-Authors: Wil M P Van Der AalstAbstract:Today's workflow management systems have problems dealing with change. Since change is a fact of life, this limits the application of these systems. As a result, the workflow management system is not used to support dynamically changing workflow Processes or the workflow Process is supported in a rigid manner, i.e., changes are not allowed or handled outside of the workflow management system. This paper addresses this problem and tackles it by using Generic Process models. A Generic Process model describes a family of variants of the same workflow Process. The approach presented in this paper allows for both ad-hoc changes and evolutionary changes. It is a first step in the direction of truly flexible workflow management systems. It turns out that the trade-off between flexibility and support raises challenging questions and that Generic Processes can answer some of these questions.

A Generic Process modelling – LCA approach for UF membrane fabrication: Application to cellulose acetate membranes
Journal of Membrane Science, 2021Co-Authors: Flavie Prézélus, Ligia Tiruta-barna, Christelle Guigui, Jean-christophe RemigyAbstract:Abstract The purpose of the research is to elaborate and implement a decision-making tool for greener membrane fabrication. The scientific novelty put forth in this study is the Generic Process modelling – LCA approach applied to the field. The resulting parameterized model allows to obtain material and energy flows as a function of operating conditions for ultrafiltration hollow fibers prepared by non-solvent induced phase separation. Its modular configuration allows for flexibility and adaptation to various membrane materials and industrial practices. Contributions of inputs on environmental impacts can be assessed, as well as the influence of operating conditions. Results for cellulose acetate membranes show major contributions of NMP (i.e. solvent) and glycerol (i.e. pre-conditioning liquid). Improvement strategies for environmental mitigation include acting on glycerol-related operating conditions and are to be considered within the geographic context of membrane fabrication; further technical and economic feasibility studies would embed these strategies in a full eco-design approach. Such a methodology and results should be taken into account for the elaboration of “green membranes” whatever the application and coupled with the impact of membrane use and end-of-life.

A Generic Process modelling – LCA approach for UF membrane fabrication: Application to cellulose acetate membranes
Data in Brief, 2020Co-Authors: Flavie Prézélus, Ligia Tiruta-barna, Christelle Guigui, Jean-christophe RemigyAbstract:In the related research article, entitled "A Generic Process modeling - LCA approach for UF membrane fabrication: Application to cellulose acetate membranes"[1], a Generic model is described and used to obtain the list of material and energy flows as a function of operating conditions for ultrafiltration (UF) hollow fibers preparation by non-solvent induced phase separation. In this data article, equations of the model, a dataset of model parameters and modelled data are detailed. modeling equations are developed from material and energy balances for each unit operation (i.e. from polymer solution mixing to module conditioning) based on an industrial membrane fabrication Process of UF cellulose acetate modules. These equations may be reused as such or adapted to other membrane materials and industrial practices. The dataset of model parameters relates to industrial on-site measurements and scientific literature for the existing cellulose-based module. The modelled data corresponds to a reference situation for which hollow fibers (inner and outer diameters equal to 0.93 mm and 1.67 mm, respectively) are fabricated from a polymer solution composition of 20 wt.% of cellulose triacetate, 78 wt.% N-methyl-2-pyrrolidone and 2 wt.% lithium chloride.
