  5. 24. Mixed-Integer Optimization Modeling for the Simultaneous Scheduling of Component Replacement and Repair

    Författare :Gabrijela Obradovic; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mathematical Modeling; Workshop Scheduling; Maintenance Optimization; Simultaneous Scheduling; Mixed-Integer Linear Optimization; Multi-Objective Optimization; Contracting Forms;

    Sammanfattning : Maintenance is a critical aspect of many industries, playing an indispensable role in ensuring the optimal functionality, reliability, and longevity of various assets, equipment, and infrastructure. For a system to remain operational, maintenance of its components is required, and for the industry to optimize its operations, establishment of good maintenance policies and practices is vital.
