An Architecture for Collaborative Scenarios Applying a Common BPMN-Repository
2005
Collaborative business scenarios require a flexible integration of enterprises. To manage inter-organizational business processes, existing concepts for business process management (BPM) need to be adopted and extended. This paper presents a conceptual architecture for cross-enterprise processes’ planning, implementation, and controlling. Core component of the architecture is a distributed repository managing all required data and information, which especially obtains a process-oriented view on collaboration networks. Cross-organizational processes need close coordination among networking partners. This is achieved through the integration of business process models. Thus we further propose …
Business models and opportunity creation: How IT entrepreneurs create and develop business models under uncertainty
2015
How can entrepreneurs develop business models for markets in which the technology is constantly changing-or create business models for markets that do not exist? These are fundamental questions for information technology IT entrepreneurs, and for information systems IS scholars who seek to develop a theoretical understanding of business models. The case study presented in this paper addressed these questions, demonstrating how a small software firm developed its business model over a 15-year period in cloud gaming markets. Based on the empirical findings, a preliminary theoretical model is presented. The aim of the model is to increase scholarly understanding of how business models are crea…
Diode laser welding of ABS: Experiments and process modeling
2009
International audience; The laser beam weldability of acrylonitrile/butadiene/styrene (ABS) plates is determined by combining both experimental and theoretical aspects. In modeling the process, an optical model is used to determine how the laser beam is attenuated by the first material and to obtain the laser beam profile at the interface. Using this information as the input data to a thermal model, the evolution of the temperature field within the two components can be estimated. The thermal model is based on the first principles of heat transfer and utilizes the temperature variation laws of material properties. Corroborating the numerical results with the experimental results, some impor…
Analysis, Modeling and Simulation of Complex Regional Clusters Activities, Using Arena Simulation Software
2014
Process modelling is the concise description of the total variation in one quantity, y, by partitioning it into a deterministic component given by a mathematical function of one or more other quantities, x1, x2... plus a random component that follows a particular probability distribution. The models are material or immaterial systems, which represent other systems, so that it may be possible to manipulate the built structures and their states. The main elements of a simulation are: attributes (describe and differentiate entities), variables (system characteristics), resources (whose capacity can be variable), tails (seen in case of unavailability of resources) and statistical accumulators (…
ISTehnology – integrated Approach to IS Development and Benefits of its Using
2011
The system ISTechnology and benefits of its usage are analyzed in the paper. ISTechnology provides an integrated approach to business modeling and development of information systems. The system consists of a meta-model and applications. The meta-model enables defining of a platform independent business model of the organization. The applications provide the definition and interpretation of the business model. Interpretation of the business model provides functionality of the information system in the selected platform. The lessons learned confirm that the development and maintenance cost of information systems can be significantly reduced by use of the ISTechnology. The paper describes addi…
Constructions of Nonagency in the Clients’ Initial Problem Formulations at the Outset of Psychotherapy
2019
This multiple case study investigated how clients construct nonagentic positions when formulating their problems in the beginning of their first psychotherapy session. The initial problem formulations of nine clients entering psychotherapy were analyzed with a detailed model drawing on discursive methodology, the 10 Discursive Tools model (10DT). We found ten problem formulation categories, each one distinguished by the tool from the 10DT model primarily used to construct nonagency. All clients gave several problem formulations from different categories and constructed nonagentic positions with a variety of discursive tools. When the resulting problem formulation categories were read in com…
Towards a method to generate GUI prototypes from BPMN
2018
Business Process Model and Notation (BPMN) provides organizations with a standard that facilitates further compression of the business process. BPMN focuses on the functional processes, leaving the development of interfaces to one side. Thereby, interface design usually depends on the subjective experience of the analyst. This article aims to propose a new method to generate user interfaces from BPMN models and Class Diagrams. The proposed method is based on the identification of different rules and makes use of stereotypes to extend BPMN notation. The rules have been extracted from seven existing projects on the Bizagi repository. Specifically, the proposal is based on the extraction of ru…
Developing a customizable process modelling environment: Lessons learnt and future prospects
1998
MetaCASE environments are design environments with customisable method support. Currently these environments are shifting from individual production support towards multi-user design environments. When adapting such an environment, the organisational context becomes important. We must focus on and improve the infrastructure (procedures and policies) and support (guidelines, help). Part of organisational support in design environments is process modelling: process models facilitate understanding and communication, process support gives guidance and helps enforcing procedures and policies. In a customisable design environment improvement is seen as a shift, a relatively gradual change that th…
2D Hydro-Mechanical-Chemical Modeling of (De)hydration Reactions in Deforming Heterogeneous Rock: The Periclase-Brucite Model Reaction
2020
Deformation at tectonic plate boundaries involves coupling between rock deformation, fluid flow, and metamorphic reactions, but quantifying this coupling is still elusive. We present a new two-dimensional hydro-mechanical-chemical numerical model and investigate the coupling between heterogeneous rock deformation and metamorphic (de)hydration reactions. We consider linear viscous compressible and power-law viscous shear deformation. Fluid flow follows Darcy's law with a Kozeny-Carman type permeability. We consider a closed isothermal system and the reversible (de)hydration reaction: periclase and water yields brucite. Fluid pressure within a circular or elliptical inclusion is initially bel…
Semantics of UML 2.0 Activity Diagram for Business Modeling by Means of Virtual Machine
2005
The paper proposes a more formalized definition of UML 2.0 Activity Diagram semantics. A subset of activity diagram constructs relevant for business process modeling is considered. The semantics definition is based on the original token flow methodology, but a more constructive approach is used. The Activity Diagram Virtual machine is defined by means of a metamodel, with operations defined by a mix of pseudocode and OCL pre- and postconditions. A formal procedure is described which builds the virtual machine for any activity diagram. The relatively complicated original token movement rules in control nodes and edges are combined into paths from an action to action. A new approach is the us…
