Designed and real working situations in machine systems operation.

N Ohashi

    Journal of Human Ergology
    |December 1, 1976
    PubMed
    Summary

    New machine systems often fail to match real work situations, causing crew difficulties and impacting work-life balance. Ergonomic evaluations are needed to address system availability and backup support for effective integration.

    Area of Science:

    • Ergonomics
    • Human-Computer Interaction
    • Maritime Studies

    Background:

    • Introduction of new machine systems often assumes consistent functionality, overlooking real-world work processes and crew skills.
    • Designed work situations may differ significantly from actual working conditions, impacting crew performance and well-being.

    Purpose of the Study:

    • To investigate discrepancies between designed and real work situations following the introduction of new machine systems.
    • To identify key factors contributing to these discrepancies, focusing on system availability and backup support.

    Main Methods:

    • Observational studies of cargo ship crews interacting with modern machine systems.
    • Analysis of factors influencing crew work stability and adherence to designed work processes.

    Main Results:

    • Crews faced challenges maintaining stable working conditions when machine systems deviated from designed functions.
    • Lack of system availability and inadequate backup systems were primary contributors to work discrepancies.
    • Crew members often worked overtime, sacrificing personal time due to system failures.

    Conclusions:

    • Ergonomic evaluation methods are crucial for assessing system availability and the need for backup systems.
    • Addressing these factors is essential for aligning designed work situations with real-world crew experiences and improving job satisfaction.
