  1. 1. SEMANTIC INFORMATION AND PHYSICAL MULTI-DOMAIN MODELING AND SIMULATION FOR POWER SYSTEMS

    Författare :Francisco José Gómez; Luigi Vanfretti; Svein Olsen; Peter Palensky; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; POWER SYSTEMS; MODELING; SIMULATION; CIM; MODELICA; ISO 15926; MULTI-DOMAIN; UML; SYSML; Energy Technology; Energiteknik;

    Sammanfattning : There are different reasons for combining different modeling languages and simulationlanguages: Exchange of more detailed information about power network components, theirparameters and, most importantly, mathematical equations describing their behavior andthe exchange of a mathematical description, using equation-based languages (e.g. LÄS MER

  3. 2. Towards Human Supervisory Control in Advanced Manufacturing Systems

    Författare :Johan Stahre; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; human; CIM; case study; operator; FMS; supervisory control; method; manufacturing; model; cross-disciplinary;

    Sammanfattning : This thesis is on the topic of Human Supervisory Control in Advanced Manufacturing Systems (AMS). Presently, these systems suffer from inferior reliability and low productivity, unless "nursed" by skilled operators. Operators controlling the AMS are approaching a work situation similar to that of operators in continuous process manufacturing. LÄS MER

  4. 3. Use of the CIM framework for data management in maintenance of electricity distribution networks

    Författare :Lars Nordström; Torsten Cegrell; Pekka Verho; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Asset Management; Electricity Distribution Networks; Information Systems; Data Quality; Power System Modeling; Enterprise Architecture; Common Information Model; Ontology; Systems engineering; Systemteknik;

    Sammanfattning : Aging infrastructure and personnel, combined with stricter financial constraints has put maintenance, or more popular Asset Management, at the top of the agenda for most power utilities. At the same time the industry reports that this area is not properly supported by information systems. LÄS MER

  5. 4. Fault tolerant control in flexible manufacturing systems

  7. 5. Analysis and direct optimization of cutting tool utilization in CAM

    Författare :Ana Esther Bonilla Hernández; Tomas Beno; Anders Wretland; Jari Repo; Jinming Zhou; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CAM programming; Material Removal Rate; Tool life; Tool wear; Tool utilization; Cutting data; Lean; Optimization; CIM; Integration IT tools; Manufacturing; Manufacturing and materials engineering; Produktions- och materialteknik; Production Technology; Produktionsteknik;

    Sammanfattning : The search for increased productivity and cost reduction in machining can be interpreted as the desire to increase the material removal rate, MRR, and maximize the cutting tool utilization. The CNC process is complex and involves numerous limitations and parameters, ranging from tolerances to machinability. LÄS MER
