Definition

Therbligs are a set of elemental movements used in the study of work and motion, defined as the basic units of human motion in industrial engineering. Developed by Frank and Lillian Gilbreth in the early 20th century, therbligs were designed to analyze and improve work processes, thereby enhancing efficiency. These elemental motions serve as the foundation for time-motion studies, which evaluate how tasks can be performed more effectively.

5 Must Know Facts For Your Next Test

  1. Therbligs categorize 18 different types of motions that people use when performing tasks, each identified with a specific symbol.
  2. The term 'therblig' itself is derived from the last names of the Gilbreths, with a deliberate rearrangement of letters.
  3. Using therbligs helps engineers and managers break down tasks into simpler components, allowing for better analysis and design of workflows.
  4. The application of therbligs has contributed significantly to advancements in ergonomics by optimizing human-machine interaction.
  5. Therbligs have laid the groundwork for modern techniques in lean manufacturing and continuous improvement by identifying wasteful motions.

Review Questions

  • How do therbligs contribute to the efficiency of industrial engineering practices?
    • Therbligs play a crucial role in enhancing the efficiency of industrial engineering practices by breaking down complex tasks into simpler, elemental motions. This breakdown allows engineers to identify unnecessary movements, streamline workflows, and improve overall productivity.
