In modern life, if you want to drink tea, but the water is not boiled, the kettle teapot and teacup are not washed, and the tea leaves have to be taken in the hall, what should I do?

It takes one minute each to wash the kettle, teapot, and teacup, one minute to take the tea leaves, ten minutes to boil the water, and how much time does it take to drink tea?

To do this, most people can arrange it very well without special instructions, and most of the time will not be wasted. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Because even if you don't understand any advanced theories of mathematics, the experience in life is enough to support the solution of such problems.

But-

What if you ask a ten-year-old who has never had experience in this field to do the same thing? Will he still do it in an orderly manner without wasting time and steps?

Or, to be more complicated, it is necessary to have a hundred people drink tea, and there are only twenty stoves to boil water, and only twenty people are allowed to boil water at the same time; There are only four places to receive a kettle, a teapot, and a teacup, and it takes half a minute for each person to receive a set; There are only two places to receive tea, and it takes 10 seconds for each person to receive a bag of tea......

And when the hundredth person drinks tea, how much time does it take?

The matter of moving the capital is like magnifying the incident of 100 people drinking tea 10,000 times......

The royal family, hundreds of officials, the army, and the common people, each kind of person is different, and the materials involved are also different, and the quantity is also huge, and the complexity can be imagined.

So how can we arrange the whole process more efficiently, so that people at each level can maximize the resources they should have, make full use of time, and make all the links fully operational?

This brings us to organizational behavior and basic co-ordination......

It may sound profound, but it's actually an advanced application of mathematical theory.

Fei potential descendants are senior fritters in the company's office, for resource allocation, staffing and so on to tear down the east wall to make up the west wall of things very skillful, and the company's every full kick-off meeting, the end of the company's annual meeting, commendation conference and other meetings, as little as a few hundred, more than a few thousand, all the venue layout, itinerary, vehicle scheduling, food and accommodation all have to be thoughtful, one of the links is a big problem......

Therefore, the content of the paper presented by Fei Qian is the overall planning itinerary for the relocation of the royal family in the Han Dynasty.

The distance from Luoyang to Chang'an is about 800 miles, and the general march is about 40 to 60 miles, which means that if you go from Luoyang to Chang'an, it will take about 15 days.

Fei Qian didn't know exactly how many palace maids and eunuchs there were in the palace of the Han Dynasty, and these data could only be counted after the Shaofu transferred out the book. Therefore, Fei Qian only roughly uses a divisor to calculate, anyway, in the Han Dynasty, if there was really something like a decimal point, it would make people confused and even more incomprehensible.

Why do ordinary people feel irritable when moving, because there are too many things to count and pack, and some of the things that are originally in order will pop up like grass, which is annoying.

What Fei Qian presented to Li Ru at this time was such a categorical statistic, divided into two parts: adults and things. The personnel chapter is the number and degree of various personnel including the emperor, while the items article is listed separately according to the four parts of clothing, food, housing and transportation, including the items of the royal family in terms of clothing, food, living, honor guards and so on during the period from Luoyang to Chang'an......

Of course, due to the limitation of paper length for these projects, Fei Qian could not write in great detail, but only wrote some general classifications, and the most important thing is a flow chart that occupies half of the paper, also called a schedule.

From Luoyang to Chang'an, with each day as the node, the location of arrival, the personnel and materials required, and the grain and grass provided by various places are indicated......

The more Li Ru looked at it, the more interesting he felt, pinching his beard, and finally a smile appeared on his face.

It's not that he doesn't understand these things, and it's not that he can't do them, all kinds of matters like the emperor's migration are in Li Ru's heart, every day, every step has been clearly considered, but Li Ru can't describe and express it as clearly as Fei Qian, so that others can also understand what they want to do after reading it, and to what extent it can be called a good job.

It's like a master craftsman who can cut a piece of wood into a standard disc at will, but if you ask him what the exact pi is, and the exact area of the disc is geometric, he will definitely not be able to answer......

Li Ru is now like such a great craftsman, everything is like a mirror in his heart, and the overall arrangement of the itinerary is all planned in his heart, but the only thing is that there is no way to completely let the people under him understand these matters in his heart.

Therefore, it can only be explained one thing at a time, and then one thing by one is re-summarized to Li Ru, and then it is calculated and consolidated in Li Ru's heart again, and then ordered to arrange personnel to carry out the next business.

How can such a huge calculation not make people feel emaciated?

How can such a tedious step not be painful?

Li Ru suddenly remembered that the Fei Qian in front of him was not only a disciple of Cai Yong, who focused on literature, but also a disciple of Liu Hong, who was highly accomplished in arithmetic......

Although Fei Qian did not write in great detail, Li Ruqu could understand the general meaning, especially in the progress table drawn in the second half of this piece of paper, which was like pushing open a window, allowing Li Ru to see another aspect of the landscape.

It turns out that this matter can still be handled in this mode!

There is a person in charge of each matter, and each person in charge has a specific daily task to complete, when to what extent, and then with whom to hand over, so interlocking, layer by layer......

What a rare trick!

For Fei Qian, this is also the data that took a whole day and several repeated deductions to sort out, of course, this is also something that Li Rucai came up with.

With the same piece of paper like this, if you show it to Lu Bu, even if you show it to him for a year, how much can you understand?

Therefore, Fei Qian is not worried about how much combat effectiveness this method can increase to Dong Zhuojun, because there is no real and specific experience, and there is no basic theory to support it, this piece of paper is just a ghost drawing, even if you read it, you may not be able to understand it, let alone use it.

This is the method that Fei Qian thought of along the way, after thinking about it for a long time, to provide Li Ru and reduce his burden, but it would not allow Dong Zhuojun to get much help in the later stage.

Even if Li Ru understands and masters this method, you must know that overall planning and organization are interdisciplinary and marginal disciplines even in modern times, and they are not something that ordinary people in the Han Dynasty can master if they know the method of arithmetic.

So this is a bargaining chip, a bait that was pushed in front of Li Ru, in exchange for the things Fei Qian wanted, of course, this bait was very sweet, which obviously aroused Li Ru's interest.

However, Li Ru obviously guessed Fei Qian's thoughts, smiled slightly, put down the paper, and asked, "Ziyuan offered this method, but did he ask for something?" ”
