    Sammanfattning : In today’s global and aggressive market system, for manufacturing companies to remain competitive, they must manufacture high-quality products that can be produced at a low cost; they also must respond efficiently to customers’ predictable and unpredictable needs and demand variations. Increasingly shortened product lifecycles, as well as product customization degrees, lead to swift changes in the market that need to be supported by capable and flexible resources able to produce faster and deliver to the market in shorter periods while maintaining a high degree of cost-efficiency.

    Sammanfattning : Cars, trains, trucks, telecom networks and industrial robots are examples of products relying on complex embedded software systems, running on embedded computers. Such systems may consist of millions of lines of program code developed by hundreds of engineers over many years, often decades. LÄS MER

  4. 3. A Simulation-Optimization Approach for Improved Robustness of Railway Timetables

    Författare :Johan Högdahl; Markus Bohlin; Oskar Fröidh; Alireza Ahmadi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railroad; Timetabling; Optimization; Simulation; Robustness; Punctuality; Delay prediction.; Järnväg; Tidtabelläggning; Optimering; Simulering; Robusthet; Punktlighet; Förseningsprediktion.; Transportvetenskap; Transport Science; Transportsystem; Transport Systems;

    Sammanfattning : The timetable is an essential part for the operations of railway traffic, and its quality is considered to have large impact on capacity utilization and reliability of the transport mode. The process of generating a timetable is most often a manual task with limited computer aid, and is known to be a complex planning problem due to inter-train dependencies. LÄS MER

  5. 4. Improving Timetable Robustness and Punctuality of Railway Traffic : A Combined Simulation-Optimization Approach for Nonperiodic Timetabling on Double-Track Lines

    Författare :Johan Högdahl; Markus Bohlin; Oskar Fröidh; Rob Goverde; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Timetabling; Train scheduling; Delay prediction; Punctuality; Railroad; Robustness; Transportsystem; Transport Systems;

    Sammanfattning : To evaluate the robustness of a timetable against minor delays, it can be simulated. A natural question following a simulation is how the results can be used to improve the timetable, which has received limited attention in the literature. LÄS MER

  7. 5. Facility layout design with simulation-based optimization : A holistic methodology including process, flow, and logistics requirements in manufacturing

    Författare :Enrique Ruiz Zúñiga; Anna Syberfeldt; Matías Urenda Moris; Masood Fathi; Jesús Muñuzuri; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Sammanfattning : Adaptability and flexibility are becoming key concepts in manufacturing. Today manufacturing companies often have to deal with random disruptive events, which necessitates significantly more complex manufacturing systems. LÄS MER
