Helicopter.

Looking at Li Xian, who was sitting opposite him and looking out of the porthole in a daze, Niu Xingbang had a toothache.

He really never thought that he, a dignified commander of a military region, would have such a day when he was requisitioned for a helicopter.

However, what he didn't expect was that the logistics and transportation projects of the Qingjiang section of the embankment before all came from the young man in front of him who looked like he was in his early twenties!

If it weren't for what Zu Qingsheng and a group of provincial leaders told him when he was on the ground just now.

"Hey, lad. ”

Niu Xingbang knocked on the porthole, attracting Li Xian's attention.

Looking at the other party pointing to the communication headset hanging above the cabin, Li Xian knew that the other party had something to say to him.

"Chief, what's the matter?"

In the nineties, the country was still quite lagging behind in the development of helicopters.

Although after the great disarmament, the state deliberately weakened the construction of the Continental Army, and began to vigorously develop the navy, air force, and special arms such as the rapid reaction aviation unit around the ratio of modern military strength. But in terms of technology research and development, it is far from keeping up.

At present, the number of helicopters assembled in various military regions across the country is extremely limited, and there is a lack of models, most of which are Z-5 installed in the sixties and seventies.

Woolly goods like the Mi-17 are already relatively advanced - there are only more than 30 in the country.

But in the cabin, even with a headset, Li Xian still felt that he had to shout and speak to the other party to be heard.

"How did you dispatch the logistics convoy on the embankment just now?"

Seeing that the other party was concerned about this issue, Li Xian smiled slightly.

Liang Yonghe's specific algorithm, as a mathematical scumbag, he can't understand it at all. But when he saw the strange route planning method modeled on the foraging behavior of ants, Li Xian's first reaction was that this thing is not a commonly used thing in civil logistics at all!

According to Liang Yonghe's own account, after he saw it in a foreign magazine, he thought that this algorithm might be useful for the construction of logistics networks in remote areas. Especially in the mountainous and hilly areas of the south, the establishment of logistics networks, this algorithm will greatly reduce the network deployment time.

However, in Li Xian's view, this algorithm is not suitable in the normal logistics field.

Normally, the establishment of an enterprise logistics network is not a simple problem of optimal path selection. Rather, it is necessary to consider various factors such as local business districts, gas stations, highway conditions, and the operating economy of each route.

Sometimes the fastest route doesn't necessarily equal the best route.

So at that time, he thought, unless this thing is a natural disaster in an area like this, and logistics need to be carried out at all costs, or ....... only military logistics, which has the greatest need for speed and efficiency, can afford to use it.

Now seeing Niu Xingbang asking, Li Xian truthfully explained the principle of Liang Yonghe's algorithm and the specific scheduling process. Of course, he didn't claim the algorithm to himself. Liang Yonghe's cheapness, he definitely can't take advantage of it.

Niu Xingbang doesn't care about these details.

After listening to Li Xian explain all the processes, the head of the military region fell into deep thought.

"I didn't expect that the gold content of private logistics is so high now?"

After a while, the old man came up with such a sentence,

"In fact, in our normal operations, we do not use this method that is so difficult for basic communication and fleet scheduling. Li Xian told the truth, but guessed Niu Xingbang's thoughts at this time, and then thought of the development direction of logistics in the next ten years, and said: "However, in the future, logistics should be more efficient routes, dispatch informatization, and rapid development of market response, which is certain." This route selection method is far more efficient than existing scheduling methods in some environments. ”

Niu Xingbang nodded, knowing that Li Xian was involved in the rescue this time, and he knew all about the situation on the front line, so he didn't hide it, and said directly: "This is also in line with the construction concept of our army's logistics department. To tell the truth, in the face of this flood disaster, some problems of the local government and our military's logistics support departments are worth considering. Comrade Li Xian, on the way here just now, I was still thinking about your dispatch method, and if possible, I hope that you can come to our military region after the disaster, and we can exchange ideas. ”

If it is usual, Li Xian may still be in the mood to talk to Niu Xingbang about the development strategy of civil-military integration, logistics companies to carry out military-civilian integration business, participate in military logistics activities, integrate into the military logistics system, provide support services for peacetime emergency and wartime military activities, as well as talent and warehouse resource sharing and other topics that have been realized in later generations.

But now, thinking about Li Pi, Li You and others in his heart, he is really not in the mood.

However, thinking that this time the floods in Shandong Province alone caused such a big trouble, the upcoming national floods in 96 and 98, and even the earthquake that shook the entire Shenzhou more than ten years later, Liang Yonghe's algorithm must have played a certain role in disaster relief and post-disaster reconstruction, Li Xian still nodded.

"Yes, I will do a paper with my classmates in the future, and make a detailed demonstration of the Monte Carlo algorithm combined with logistics scheduling, and we will contact each other when the time comes. ”

casually agreed, Li Xian stopped speaking, turned his head and looked out the window again.

Outside the porthole, Liaocheng is already faintly visible.

It's just that this beautiful and peaceful city in the past is now an ocean from the sky.

......

Xie Jiazhuang.

Li You and Xie Laohan were already back to each other.

It's not that the forsythia relationship is good, but that the water under the feet has not reached the roof. There is only a few square meters of space left on the roof that can stand people!

At this time, the two families were forced by the flood to stand together.

But huddling obviously can't bring much security to everyone.

An hour ago, the flood water had risen sharply, and the waves were rolling up roots and debris from unknown sources, like a broken cone on an ancient battlefield, hitting the underwater brick wall with a muffled sound.

Lao Xie's family has two houses, and the one everyone is standing on now is the one that was just renovated for Xie Lao Er last year and was ready to be used as a wedding room.

More than half a month ago, Xie Laohan still complained that the house had been repaired, and his daughter-in-law was not in place. But now it seems that it is also a loss to prepare this new house - the old house that has not been repaired before it has been dumped in the flood as early as nine o'clock this morning, and disappeared with the waves.

"Hey! Sun Erfu'er's house is gone! Oops, oops, it's down! Erfu'er!"

Not far away, another muffled sound came.

In just a few seconds, the black roof rolled up the villagers who had taken refuge on it and disappeared into the floodwater.

Seeing that his old neighbor for many years only fluttered a few times in the yellow water and disappeared again, Xie Laohan couldn't help but burst into tears.

Zou Limei hugged her frightened little granddaughter who was crying in her arms, and she also cried at this time.

This water came for a total of less than a day, standing on the roof, it turned out that more than a dozen blind dates were gone.

"God, what kind of sin is this!" In the midst of the howl, Zou Limei slapped her thigh fiercely.

Sun Erfu'er, what a good person is that?

Usually silent, everyone laughs when they see it. When she moved to this village more than 20 years ago, Zou Limei had never seen Sun Erfu'er blushing with anyone. The sister-in-law of the Sun family is even more sophisticated, and she can't pick out half of the words.

But now, the old grandson's family is gone.

Seeing that Xie Laohan was howling in the direction of the old Sun family who had disappeared, Li You patted him on the back.

He is not familiar with Lao Sun's family.

It is inevitable that the rabbit will die and the fox will be sad.

Looking at the water under his feet and seeing it rising, he was pulling out the cold in his heart.

"Old Xie, don't cry. Looking at the urine sex, we will also get a report from the Dragon Lord in a while. ”

As he spoke, Li You couldn't hold back himself.

Wow and cried.

Day donkey, day donkey!

Lao Tzu has just passed two good times, the eldest son's family is not noisy, the second son has become a billionaire, and he has become an official.

Damn, you said it's okay, come over and go to which relatives, what kind of eggs to pretend!

Dada......

Just when Li Youlao was in tears, sighing in his heart for the hero's thin life.

Overhead, the sound of a propeller was heard.

"Don't move, the plane can't get off. On the eaves, Li Qing shrunk his neck, and the long cold and hunger made his lips white.

"Dad, haven't you seen a helicopter for fire prevention in our forest area? Take a turn and leave, you can save some effort and keep the house for a while before it collapses. ”

Looking at Li Lingling in his arms, he muttered.

The two families seemed a little lonely because of this sentence.

At this moment, Li You suddenly stretched his neck.

"Oh, something is wrong, this plane is coming for us!"

"Oh, look, the door of the plane is open, hey, hey, !! second son!

Seeing the helicopter hovering down in the sky, a familiar figure appeared in the open hatch, Li You jumped up happily.
