Chapter 427

As a very popular branch in the field of applied mathematics, fuzzy mathematics can be said to be able to involve all aspects of production and life.

For example, fuzzy cluster analysis, fuzzy pattern recognition, fuzzy comprehensive evaluation, fuzzy decision-making and fuzzy prediction, fuzzy control, fuzzy information processing, etc.

After decades of tireless research by several generations of mathematicians, these methods constitute a fuzzy system theory and the prototype of speculative mathematics, which has achieved specific research results in medicine, meteorology, psychology, control, remote sensing, education, sports, etc.

And this conference on the application of fuzzy mathematics was born in this environment.

With the fame of the previous two sessions, this academic exchange conference not only created a record number of participants, but also greatly increased the attention of the outside world.

Therefore, even though it is still during the Spring Festival holiday, several academic journals have sent their own reporters to record the whole process.

In this way, at ten o'clock in the morning, with an old man over seventy years old sitting on the main seat, the third academic exchange conference based on fuzzy mathematics application research was officially held!

After a short opening speech by Professor Ji Peisheng, director of the Kyoto Institute of Applied Mathematics, the organizer of the conference, the theme was quickly decided.

Based on fuzzy mathematics, this session will focus on its application in road traffic.

There were less than four hours of meeting time, and time was tight, and no one would talk about it for a long time.

Obviously, the theme of the conference had already been revealed to the invited mathematicians, so everyone looked at each other and then began to take turns presenting their ideas.

Cheng Nuo didn't want to come in vain, so he sat in an inconspicuous corner, took out the notebook in his backpack, and listened attentively to the speeches of the bigwigs while consulting information about this area.

Different people have different ideas about the application of fuzzy mathematics in road traffic.

The first mathematician said that it is possible to apply the fuzzy information processing of fuzzy mathematics and the characteristics of fuzzy decision-making to the automatic driving navigation of intelligent vehicles?

After discussion, it is felt that the current technology application conditions are not mature, and it is easy to ignore the danger caused by small factors in the process of autonomous driving by using this method of fuzzy information, and the instability is extremely high.

The first proposal, after a brief discussion by the public, was rejected.

The mathematician was just frustrated for a while, and then enthusiastically moved on to the next proposal.

It is proposed to apply fuzzy mathematics to the assessment of road safety in mountainous areas, and it is also said that fuzzy mathematics can be used to perform simple fuzzy identification in real-time traffic conditions of roads to speed up feedback. There is also a more cerebral idea, saying that the concept of fuzzy sets in mathematics can be blurred, and the distance and location of high-speed toll stations can be re-planned......

Cheng Nuo took a small notebook and recorded it silently on the side.

Some of these proposals were directly rejected or temporarily shelved, but they were confirmed to be feasible and could be applied to the actual road traffic field, and only one was discussed for a long time, and only one was shelved.

It was proposed by Professor Fang that the application of fuzzy mathematics to the assessment of road safety in mountainous areas.

Even Professor Zhou's proposal to apply fuzzy mathematics to the selection of high-speed sections was found to have many shortcomings after some discussion, and was temporarily shelved.

However, although the proposal put forward by Professor Fang is applicable, after some estimation by everyone, it is found that the actual economic value created is not high.

The main reason is that most of the mountain roads in China have been evaluated for safety, not to mention, the use of fuzzy mathematics method for evaluation, although the equipment will be reduced a lot, but the data that needs to be measured, or the difficulty of evaluation, has been increased by more than two or three times, and it is difficult to be popularized throughout the country.

It is estimated that the economic benefits/reduced economic losses that can be created by this patent are only three or four million at most.

Professor Ji Peisheng, who was sitting in the main seat, had already frowned slightly.

Now that the process of the meeting is almost halfway through, there is only one proposal that can be adopted, and it is still difficult to create high economic benefits.

He remembered that at the time of the conference, their Institute of Applied Mathematics shouted more slogans in front of reporters than the previous two sessions.

Looking at the current situation, let alone exceeding, it would be good to be able to compare with the results achieved in the first session.

If this continues, I am afraid that there will be no more Fourth Conference!

Professor Ji Peisheng sighed lightly in his heart.

The meeting continued.

The next speaker was a professor from Beihang University, who proposed the application of fuzzy mathematics to the structural analysis of asphalt pavement.

The theoretical support is the knowledge of fuzzy measurement and integration in fuzzy mathematics, through which the loss of raw materials is minimized while maintaining the stability of the pavement structure.

However, as soon as the professor finished speaking, he was vetoed by the professors.

After a few words of theory, the professor realized that his proposal had many loopholes, and he kept silent.

Just as everyone was about to jump to the next topic, a hand suddenly rose out of place.

"Uh...... That, can you let me say a few words?" Cheng Nuo said tentatively.

There was an eerie silence for a few seconds.

Then, it seemed to be rehearsed, and they all looked at Cheng Nuo who was sitting in the corner.

At first glance, I don't know!

Second glance, who is this?

At third glance, some people feel a little familiar.

Before everyone could figure out the identity of the man. Professor Ji, who was sitting in the main seat, had already said with a smile, "This conference is for the purpose of communication, and it will not restrict anyone's right to freely express their views." ”

In front of a bunch of bigwigs in the field of numbers, Cheng Nuo was still a little nervous.

Under the gaze of everyone, he said cautiously, "Actually, I just expressed my opinion on Professor Li's plan for asphalt pavement just now. ”

Seeing that everyone was silent, Cheng Nuo lowered his head and glanced at the things he had written down in his notebook, and said slowly without hurrying, "My point of view is different from yours, I think that the theory of fuzzy mathematics can be applied to the analysis of asphalt pavement structure today." ”

"Oh?"

Several bigwigs immediately raised their eyebrows, expressing their inner curiosity.

They were curious to see what else the young man could say about the plan that had been rejected by all of them.

You continue. Professor Ji Peisheng also urged.

Cheng Nuo pondered for half a second, "My entry point is different from Professor Li's. Professor Li is based on the theory of fuzzy measures and integrals, and I think the use of fuzzy reliability analysis is the best choice. ”
