Chapter 424 Application of Fuzzy Mathematics

427 chapter

As a very popular branch in the field of applied mathematics, fuzzy mathematics can be said to be involved in 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 a prototype of speculative mathematics. It has been used in medicine, meteorology, psychology, control, remote sensing, education, sports, etc. specific research results.

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

Thanks to the reputation achieved in the previous two sessions, this academic exchange conference not only created a record high number of participants, but also greatly increased the attention of the outside world.

Therefore, even during the Spring Festival holiday, several academic journals sent 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 on applied research based on fuzzy mathematics was officially held!

The organizer of the meeting, Professor Ji Peisheng, director of the Institute of Applied Mathematics in Kyoto, gave a short opening speech, and then quickly determined the theme.

Based on fuzzy mathematics, this session mainly discusses its application in road traffic.

There was only less than four hours of meeting time, and the time was tight, so no one would make a long speech.

Apparently, the theme of the meeting had been disclosed to the invited mathematicians, so everyone looked at each other first, and then began to state their ideas in turn.

Cheng Nuo didn't want to come here in vain, so he sat in an inconspicuous corner, took out the notebook from his backpack, and while looking up information on this matter, he listened distractedly to the speeches of the big bosses.

Regarding the application of fuzzy mathematics in road traffic, different people have different ideas.

The first mathematician said, is it possible to apply the fuzzy information processing of fuzzy mathematics, as well as the characteristics of fuzzy decision-making, to the automatic driving and navigation of intelligent vehicles?
After discussion, I feel that the current technical application conditions are not mature, and using this method of fuzzing information, it is easy to ignore the danger caused by small factors in the process of automatic driving, and the instability is extremely high.

The first proposal was rejected after a brief discussion by everyone.

The mathematician was only frustrated for a while, and then enthusiastically participated in the discussion of the next proposal.

It is proposed to apply fuzzy mathematics to the safety assessment of mountainous roads, and it is also said that fuzzy mathematics can be used for simple fuzzy identification in real-time traffic conditions on the road to speed up the feedback.There is something even more imaginative, 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 took notes silently.

Some of these proposals were directly rejected, and some were temporarily shelved, but it was confirmed that it was feasible and could be applied to the actual road traffic field. After a long discussion, there were only a few of them.

It was proposed by Professor Fang, the proposal to apply fuzzy mathematics to the safety assessment of mountainous roads.

Even Professor Zhou's proposal of applying fuzzy mathematics to the selection of expressway sections was temporarily shelved after many discussions were found to have many flaws.

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

The main reason is that most of the mountainous roads in Huaguo have already undergone safety assessments. What's more, using fuzzy mathematics methods for assessments will reduce the equipment a lot, but the data that needs to be measured, or the difficulty of assessments, will be increased. More than two or three times, it is difficult to be popularized throughout the country.

It is estimated that the economic benefit/reduced economic loss that this patent can create is only 400 million at most.

Professor Ji Peisheng, who was sitting at the main seat, frowned slightly.

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

He remembered that when the meeting was held, their Institute of Applied Mathematics shouted more slogans than the previous two sessions in front of reporters.

But looking at the current situation, not to mention surpassing, it would be good to be able to match the results achieved in the first session.

If this continues, I am afraid that there will be no fourth session!
Professor Ji Peisheng sighed inwardly.

The meeting continues.

The next speaker was a professor from Beihang University. The content of the proposal was about the application of fuzzy mathematics in the analysis of asphalt pavement structure.

The theoretical support is the knowledge of fuzzy measurement and integral in fuzzy mathematics. Through fuzzy evaluation, the loss of raw materials will be minimized while maintaining the stability of the pavement structure.

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

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

Just when everyone was about to jump to the next topic, a hand was suddenly raised inappropriately.

"Uh... Well, can I say a few words?" Cheng Nuo asked tentatively.

There was an eerie silence for a few seconds.

Then, as if rehearsed, they all looked at Cheng Nuo who was sitting in the corner.

At first glance, I don't know!
Second glance, who is this?
The third eye, some people feel a little familiar.

Before everyone can figure out the identity of that person.Professor Ji, who was sitting at the main seat, said with a smile, "This session is for the purpose of communication, and will not restrict anyone's right to freely express their opinions."

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

Under the gaze of everyone, he said cautiously, "Actually, I just want to express my opinion on Professor Li's proposal on asphalt pavement just now."

Seeing that everyone was silent, Cheng Nuo lowered his head and glanced at the things he wrote down in his notebook, and said slowly, "My point of view is different from that of you. It can be fully applied to the analysis of today's asphalt pavement structure."

"Oh?"

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

They were very curious, what else could this young man say about the plan that was rejected by all of them.

"Go ahead." Professor Ji Peisheng also urged.

Cheng Nuo pondered for half a second, "My entry point is different from that of Professor Li. Professor Li uses fuzzy measure and integral as his theoretical support, and I think using fuzzy reliability analysis is an optimal choice."
