  1. 21. A Unified Framework for e-Commerce Systems Development : Business Process Pattern Perspective

    Författare :Prasad M. Jayaweera; Paul Johannesson; Hans Weigand; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; e-Commerce; Business Model; Process Model; UMM UN CEFACT’s Modeling Methodology ; BPMN Business Process Modeling Notation ; Speech Acts; REA Ontology Resource-Event-Agent Ontology ; Enterprise Modeling Ontology; ebXML Electronic Business using eXtensible Markup Language ; Business Collaboration; Computer science; Datavetenskap;

    Sammanfattning : In electronic commerce, systems development is based on two fundamental types of models, business models and process models. A business model is concerned with value exchanges among business partners, while a process model focuses on operational and procedural aspects of business communication. LÄS MER

  4. 23. Model-Driven Process Design : Aligning Value Networks, Enterprise Goals, Services and IT Systems

    Författare :Erik Perjons; Paul Johannesson; Anders G. Nilsson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; business process design; e-process design; model-driven methods; enterprise modelling; business modelling; enterprise goals; services; value networks; business-IT alignment; design science; Computer and systems science; Data- och systemvetenskap; Computer and Systems Sciences; data- och systemvetenskap;

    Sammanfattning : The purpose of business-IT alignment is to optimise the relation between business and IT in order to maximise the business value of IT. Successful business-IT alignment can be enabled by business processes and e-processes functioning as adaptive mediators between business and IT systems. LÄS MER

  5. 24. Identification of Stochastic Nonlinear Dynamical Models Using Estimating Functions

    Författare :Mohamed Abdalmoaty; Håkan Hjalmarsson; Adrian Wills; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prediction Error Method; Maximum Likelihood; Data-driven; Learning; Stochastic; Nonlinear; Dynamical Models; Non-stationary Linear Predictors; Intractable Likelihood; Latent Variable Models; Estimation; Process Disturbance; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Data-driven modeling of stochastic nonlinear systems is recognized as a very challenging problem, even when reduced to a parameter estimation problem. A main difficulty is the intractability of the likelihood function, which renders favored estimation methods, such as the maximum likelihood method, analytically intractable. LÄS MER

  7. 25. Köp av tjänster för ledningskompetens - en polyfonisk process

    Författare :Jörgen Hansson; Per-Olof Berg; Andreas Werr; Flemming Poulfelt; Stockholms universitet; []
