  1. 1. Towards Increasing Operational Flexibility in Final Assembly using Industry 4.0 Enabling Technologies

    Författare :Omkar Salunkhe; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; collaborative robot application; final assembly; operational flexibility; Industry 4.0;

    Sammanfattning : Manufacturing companies are continuously trying to make their production systems, especially final assembly systems, resilient as environmental uncertainties increase and customer demands change. Operational flexibility offers the resilience and flexibility to help companies overcome difficult conditions quickly and remain competitive. LÄS MER

  3. 2. Optimal Energy and Flexibility Dispatch of Grid-Connected Microgrids

    Författare :Kyriaki Antoniadou-Plytaria; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexibility; microgrids; Battery energy storage; optimization.; energy scheduling; energy management; distribution network;

    Sammanfattning : This thesis proposes an optimization model to efficiently schedule energy and flexibilities of a grid-connected microgrid (MG) with non-dispatchable renewable energy sources and battery energy storages (BESs). The model can also be used to coordinate the MG operation with the connected upstream distribution grid and to assess the MG flexibility considering economic viability, technical feasibility, and BES degradation.

    Sammanfattning : Introduction: Line mangers’ and employees, registered nurses and assistant nurses’, in health care often have a demanding work situation. Sick leave illness and lack of competent staff is a problem. There is a lack of studies on working conditions, such as flexibility and restricted control, from an organizational perspective, (i.e. LÄS MER

  5. 4. Combined heat and power plant flexibility - Technical and economic potential and system interaction

    Författare :Johanna Beiron; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combined heat and power; Flexibility; Process optimization modeling; Electricity price volatility; Waste to energy; Combined cycle; District heating; Dynamic modeling;

    Sammanfattning : The share of variable renewable energy sources in electricity generation systems is expected to increase, leading to increased variability in the load that must be provided by conventional power plants or other flexibility measures. Thus, thermal power plants need to consider implementation of technical measures that enhance flexibility; to maintain profitability of operation with increased electricity price fluctuation, and to support electricity system stability.

  7. 5. Retail trade demands on distributors : strategic and operational implications

    Författare :Markus Henningsson; Linköpings universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Sammanfattning : The global trend of consolidation holds true also within the British Do-It-Yourself (DIY) retail trade and Builders Merchants (BM), resulting in inter alia the rise of 'mega-retailers' such as B&Q. The manufacturers and suppliers of wood products have been slow in the adaptation to the changed market situation. LÄS MER
