1. Subject:
Motion analysis divides human motion into 18 basic motifs, including grasping, grasping, stretching, bending, pushing, pulling, lifting, releasing, turning, bending, straight, stepping, jumping, running, walking, sitting and squatting. These patterns are the basis of various complex movements of the human body.
2. Dynamic analysis:
By decomposing and classifying the actions in the work process, unnecessary motifs are identified, thus simplifying the work flow and improving the work efficiency. This method is helpful to find and eliminate the waste phenomenon in the work, thus realizing the optimization of the work process.
3. Theme map:
In order to facilitate analysis and recording, Mr. and Mrs. Gilbres invented a recording tool called "Therblig Chart". This chart uses a series of symbols and abbreviations to represent different topics, which is helpful to analyze and improve the working process.
4. Theme time:
Action analysis pays attention not only to the morpheme itself, but also to the time it takes. By measuring the time required for each element, we can find out the bottlenecks and improvement points in the work, thus improving the overall work efficiency.
5. Pattern optimization:
By optimizing themes, that is, reducing unnecessary themes, merging similar themes and simplifying workflow, work efficiency can be improved and work intensity can be reduced.
Action analysis is widely used, not only in industrial production, but also in service industry, medical treatment, sports training and other fields. Through action analysis, we can optimize the workflow, improve work efficiency, reduce work intensity, improve job satisfaction, and also help to prevent and reduce work-related injuries.
In a word, the principle of action analysis was first put forward by American engineer Frank Buchan Gilbreth and his wife Esther Gilbreth in 19 12, which optimizes the workflow and improves the efficiency by analyzing the basic units of human actions.
