  1. 6. Modular Learning and Optimization for Planning of Discrete Event Systems

    Författare :Fredrik Hagebring; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete optimization; large-scale optimization; modular learning; automation; discrete event systems; active learning; Compositional optimization;

    Sammanfattning : Optimization of industrial processes, such as manufacturing cells, can have great impact on their performance. Finding optimal solutions to these large-scale systems is, however, a complex problem. They typically include multiple subsystems, and the search space generally grows exponentially with each subsystem. LÄS MER

  2. 7. Discrete-Event Simulation, Operations Analysis, and Manufacturing System Development: Towards Structure and Integration

    Författare :Lars Holst; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integration; Manufacturing System Development; Discrete-Event Simulation; Production technology; Produktionsteknik;

    Sammanfattning : After more than four decades of presence in the manufacturing industry, discrete event simulation has established itself as a powerful technology for a wide range of strategic, tactical, and operational applications in production, logistics, and supply chain management. Discrete event simulation software packages - although not entirely adequate - are relatively capable, and methodologies for performing simulation projects are reasonably well-developed and documented.

  3. 8. INCREMENTAL FAULT DIAGNOSABILITY AND SECURITY/PRIVACY VERIFICATION

    Författare :Mona Noori-Hosseini; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Temporal logic; Anonymity; Opacity; Discrete event systems.; Automation; Formal verification; Fault diagnosability; Incremental abstraction;

    Sammanfattning : Dynamical systems can be classified into two groups. One group is continuoustime systems that describe the physical system behavior, and therefore are typically modeled by differential equations. The other group is discrete event systems (DES)s that represent the sequential and logical behavior of a system. LÄS MER

  4. 9. Haulage system optimization for underground mines : A discrete event simulation and mixed integer programming approach

    Författare :Abubakary Salama; Jazek Paraszczak; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Sammanfattning : In coming decades, many underground mines will operate at greater depths, which will affect many operational factors such as increased rock stress, longer haulage distances, and higher energy consumption, which potentially can generate lower production rates. The increased rock stresses may lead to smaller sized openings, further restricting the size of loading and hauling equipment that can be used. LÄS MER

  5. 10. Integrating Discrete Event Simulation into the Engineering Process Strategic Solutions for Increased Efficiency in Industrial System Development

    Författare :Pär Klingstam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; discrete event simulation; manufacturing system development; simulation methodology; simulation strategy; engineering integration;

    Sammanfattning : Efficient development processes are the key to being competitive, signified by short development lead times, low development costs, and high quality in all development activities. Previous research in academia as well as in industry suggested two important facilitators for obtaining such processes, namely structured development and modeling and simulation. LÄS MER
