About
To introduce the basic concepts and the important issues (related to theory and application) inergonomics and human factors engineering for worksystem performance and product design improvement, and the use of these concepts and technologies to select jobs and situations in industries. The knowledge in the topics as mentioned in the course outline is essential to achieve these objectives. The course is intended to be designed for creating a knowledge-base of the state-of-the-art ergonomic/human factors-based worksystem in manufacturing and service organizations. The course is designed to teach the basic concepts and tools and techniques and methods employed in the broad area of human factors engineering focusing on anthropometric principles in the worksystem design, work capacity and fitness for work, work posture and body mechanics, design of physical environment, design of manual material handling tools and hand tools, and ergonomic performance of different kinds of worksystems.
Intended audience: Students belonging to disciplines like Industrial Engineering and Management, Agricultural Engineering Production Engineering, Manufacturing Science and Engineering, Mechanical Engineering and allied disciplines
