Analysis method of production action of silica
There are many methods to analyze the production action of silica, and there are four mainstream methods. The most basic is gilbraith's kinetochore analysis. The second is MTM (method time measurement), which contains a lot of content and has published many versions. The most common is mtm-2 revised by American brown in 1976; The third is Maynard's most, also known as Maynard operation sequencing technology; The fourth is the simplest and easiest to use, which is the mod (model scheduling method) developed by haid.

The purpose of action analysis is to study the method of homework in a more microscopic and detailed way. Originally, a few seconds is very short, and your eyes will pass as soon as you open and close. Because the action is very fast, you may also feel that there is no problem, but after the action analysis, you will find that waste is everywhere, and there are indeed redundant actions, so the direction of improvement will roughly appear. These action analysis methods mentioned above provide many principles and rules for work improvement, which we can learn from, but that is not all. More improvement should come from continuous practice, exploration and new thinking. As long as we apply the most basic ECRs principles and the four action economic principles well, we can create more methods.

The actions we really need are only those that produce value, such as white carbon black production, taking, moving, adjusting direction, assembly, inspection and placement. The only meaningful actions are assembly. We can improve the rest of the actions, and we should find ways to eliminate and simplify them. The hand can be changed into automatic feeding, gravity feeding, and even direct operation without taking it; The movement of the arm can be replaced by a machine, which can shorten the moving distance; As for the adjustment direction, we can use machine screening, simple silica containers to screen, and error proof design to ignore the adjustment; As for inspection, we can optimize the inspection procedures, use electronic equipment, use special inspection tools, or even cancel; For placement, you can send it automatically, pack it automatically, or implement barrier free placement, etc.


So the most important thing is not necessarily to master more laws, nor to learn more mechanical knowledge, but to persist in thinking. You can't say I don't understand if you have any problems. I don't understand, do I? Can I learn it right away? Can you think with your own mind? In fact, many things don't need profound theories. As long as we know a little physics, chemistry and common sense of silica, we can think, try, study and practice.
