Hua Luogeng The overall planning method is a mathematical method for arranging the work process. Its practical scope is extremely wide, and it can be applied in enterprise management and infrastructure construction, as well as in the organization and management of complex scientific research projects. How to apply it? The main thing is to arrange the process well. For example, I want to make a pot of tea. The situation at that time was: there was no boiling water; the kettle needed to be washed, the teapot, and the teacups needed to be washed; the fire was lit, and the tea leaves were available. what to do? Method A: Wash the kettle, fill it with cold water, and put it on the fire; while waiting for the water to boil, wash the teapot, wash the teacups, and take the tea leaves; wait for the water to boil, and make tea to drink. Method B: Make some preparations first, wash the kettle, wash the teapot and cups, and get the tea leaves; when everything is ready, fill the water and boil it; wait for the water to boil and make tea. Method C: Wash the kettle, fill it with cold water, put it on the fire, and wait for the water to boil. After the water boils, hurriedly find tea leaves, wash the teapot and cups, and make tea to drink. Which way saves time? We can see at a glance that the first method is better, but the latter two methods are useless. This is a small thing, but it is an introduction that can lead to useful methods in production management and other aspects. You cannot boil water without washing the kettle, so washing the kettle is a prerequisite for boiling water. You can't make tea without boiling water, tea leaves, and washing the teapot and cups, so these are the prerequisites for making tea. Their mutual relationship can be represented by the following arrow diagram: the number on the arrow shaft indicates the time required for this action, for example, 15 means that the time from putting the water on the stove to the time it boils is 15 minutes. It can be seen at a glance from this picture that method A takes 16 minutes in total (while methods B and C take 20 minutes). If you want to shorten working hours and improve work efficiency, you should focus on boiling water instead of tea leaves. At the same time, it only takes 4 minutes to wash the teapot, cups, and take the tea leaves. You can use the time "waiting for the water to boil" to do it. Yes, this seems to be nonsense, and it is not very high-level talk. Just like walking on two legs, eating one bite at a time. Everyone understands these principles. But there are often situations where things change slightly and people become confused when things happen. In the intricate technological processes of modern industry, it is often not as simple as making tea and drinking it. There are many tasks, hundreds, thousands, or even tens of thousands of tasks. There are many relationships, they are complicated and complicated, and there are often situations where "everything is ready, all we need is the east wind". Because one or two parts were not completed, the delivery time of a complex machine was delayed. Or often because the key is not grasped, three shifts overnight are done in a hurry. After completing this link, you have to wait for the next link to assemble. Washing the teapot, washing the teacups, and taking the tea leaves, whether they come first or later, does not matter much, and they are all the same person's work, so they can be combined into: Using numbers to represent tasks, the above graph can be written as: (? Wash the kettle? Boil the teapot Boiling water? Washing teapots and cups, taking tea leaves? Making tea) It seems like "making a fuss out of a molehill", but when there are too many work steps, doing this is very necessary. What we are talking about here is mainly about time, but in specific production practice, there are many other aspects. And it is not without benefit for us to use this method to consider the problem. Of course, this method requires full cooperation and can therefore function more effectively under a socialist system. Definition As the saying goes: "It is difficult to bloom flowers that are bright, fragrant and resistant to cold and snow in a greenhouse. Only through hardship can one hope to achieve success." The success of Comrade Hua Luogeng, a famous Chinese mathematician, is due to his ups and downs. experience. Since the 1960s, he has applied mathematical methods to practice, screened out optimization methods and coordinating methods with the goal of improving work efficiency, and achieved significant economic benefits. Comrade Hua Luogeng is a contemporary self-taught scientific master and a world-famous mathematician. He is the founder and pioneer of research in many aspects such as analytic number theory, canonical groups, matrix geometry, automorphic function theory and multi-complex variable function theory in China. It laid the foundation for future matrix geometry and so on.
