1, capacity evaluation, resource optimization, continuous improvement of production efficiency, and assistance to the production line to solve problems;

2. Formulate standard working hours and personnel quota as the basis for improving factory efficiency and cost evaluation;

3. Plan factory layout, optimize logistics, improve space utilization, optimize assembly line logistics, arrange assembly lines reasonably, and maximize efficiency;

4. Action research (MOD method) to improve operation mode and line balance, improve operation efficiency and reduce material scrap;

5, standardized analysis and research (job analysis, process analysis), to determine the standardized process, improve management efficiency;

6, manufacturing cost analysis, reduce scrap cost and manufacturing cost;

To be an IE engineer, you need to plan the layout and design tools, so you must know CAD, and the improved results should be well displayed, so you must also know PPT production.

Industrial engineering is a new engineering science. As early as 188 1 years ago, Frederick W taylor had the concept of industrial engineering, but in fact, the science of industrial engineering only began in the1920s, and only began to take shape after World War II. In foreign countries, Taylor first advocated "the study of time", while Mr. and Mrs. Gilbress (F.B. &; Gilbreths) is the founder of "engineering research". (Editor's Note: For the origin of Chronology Engineering, see the article "Two Short Stories of Industrial Engineering" on another page. ) It was not until the 1930 s that their research was paid attention to by the public and officially became the study of movement and time. Now, time research can be said to be the most basic part in the field of industrial engineering and the basic concept of traditional industrial engineering.

At first, the definition of man-hour science refers to the study of operation methods, materials, tools and equipment and time needed to complete a job. And its purpose is to find the most economical and effective working method in 1; 2. Further confirm and stipulate the selected working methods, material standards, tool specifications and ideal standards for equipment requirements; 3. Study and formulate the standard time required for workers to complete their work; 4. Training and practical implementation of new methods.

The American Institute of Industrial Engineers (A Ⅱ E) defines industrial engineering as: "Industrial engineering is a science that studies the design, improvement and application of the whole system of people, materials and equipment. It uses the professional knowledge and skills of mathematics, natural science and social science, and uses the principles and methods of engineering analysis and design to plan, predict and evaluate the effects obtained from this and related systems. 」

From the above definition, readers may have a general understanding. To sum up, all human and non-human activities, as long as they have actions, can apply the principles of industrial engineering and a set of systematic technologies of industrial engineering to achieve their goals in the best way. For example, in the operation sequence analysis of industrial engineering, because any human action is coherent, all actions are carefully analyzed, divided into fine units, unnecessary actions are deleted, and related actions are merged to simplify the work and save time and effort.
