1. 1. Duplicate systems : investigating unintended consequences of information technology in organizations

   Författare :Henrik Wimelius; Jonny Holmström; Lars Mathiassen; Jan Damsgaard; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; IS and organization; adoption of IT; assimilation of IT; change; dialectics; paradox; duplicate systems; contradiction; unintended consequences; information systems; Informatics; Informatik;

   Sammanfattning : The organizational consequences of information technology (IT) constitutes a core focus in information systems (IS) research. The relationship between organizations and IT has received considerable attention by IS researchers in order to develop knowledge related to how and why organizations and IT are related. LÄS MER

3. 2. Model-driven Alignment : Linking Business Strategy with Information Systems

   Författare :Constantinos Giannoulis; Jelena Zdravkovic; John Krogstie; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Alignment; Business; Strategy; Information; Systems; Requirements; IS; Enterprise; Models; Modeling; Computer and Systems Sciences; data- och systemvetenskap;

   Sammanfattning : Information technology (IT) is more pervasive than ever before, constituting a significant factor for performance and survival in the business arena. It is essential that IT within organizations understands what the Business needs in order to provide the necessary support and bring value, which is also true when IT is also the main value creator.

4. 3. Towards Model-Based Development of Self-Managing Automotive Systems : Modeling, Simulation, Model Transformations and Algorithms: Supporting the Development of the DySCAS Middleware

   Författare :Tahir Naseer Qureshi; Martin Törngren; DeJiu Chen; Ivica Crnkovic; KTH; []
   Nyckelord :Dynamic Reconfiguration; DySCAS; Self-Managing Systems; Load Balancing; Quality of Service QoS ; Model-Based Development; Modeling; Simulation; Model Transformation; Middleware; Embedded Systems; Component Based Design; Unified Modeling Language UML™ ; Discrete Event Systems; Real-Time Systems; Software Architecture; Simulink®; SimEvents™; Distributed Systems.;

   Sammanfattning : With the increased usage of electronics, embedded computer systems, software and networks in modern vehicles, the complexity is also increasing in terms of the development process, functionalities as well as their implementation. On one hand there is a need for efficient and systematic development, and on the other hand the systems are required to have enhanced post-deployment time configuration management support. LÄS MER

5. 4. Hierarchical Concurrent Systems from a Model-Oriented perspective

   Författare :Daniel Einarson; Data Vetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; control; systems; numerical analysis; Computer science; Distributed Systems; Hierarchical Systems; Object-Orientation; Model-Orientation; Datalogi; numerisk analys; system; kontroll; Systems engineering; computer technology; Data- och systemvetenskap;

   Sammanfattning : Real world systems are normally considered as hierarchically organized, for example, we see those as hierarchies of systems including subsystems. Examples on this can be seen in organizations where people act in environments and carry within themselves their own internal subsystem of thinking processes. LÄS MER

7. 5. Decentralized Control of Networked Systems : Information Asymmetries and Limitations

   Författare :Farhad Farokhi; Karl Henrik Johansson; Jeff S. Shamma; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked Control Systems; Decentralized Control; Limited Model Information; Transportation Systems; Sensor Scheduling;

   Sammanfattning : Designing local controllers for networked systems is challenging, because in these systems each local controller can often access only part of the overall information on system parameters and sensor measurements. Traditional control design cannot be easily applied due to the unconventional information patterns, communication network imperfections, and design procedure complexities. LÄS MER
