Chapter 366 (2/2)

Hull opened a document on his computer and explained to Cheng Nuo the project they were working on.

Cheng Nuo pulled a chair and sat down to get to know their project.

At present, the whole ”Fresnel Research Office”, er, Cheng Nuo temporarily calls this research group with Professor Fresnel as the core.

Fresnel Research Office, there are two ongoing projects.

One is a project led by Fresnel and assisted by sylvier and three other assistants. It's a project jointly approved by the Cambridge Institute and the Massachusetts Institute of technology to study the field of geometry.

The other project, of course, is hull's.

A linear modeling project about financial chaotic system.

This project is not a research task assigned by the state or the school, but an outsourcing project privately received by Professor Fresnel.

The so-called outsourcing project refers to the fact that some companies do not have the strength to carry out the project, so the project is handed over to other people, and they just pay for it.

And Professor Fresnel's brand is here. I'm afraid there are many companies willing to hand over the outsourcing project to him.

Therefore, after a period of time, Professor Fresnel will take over several outsourcing projects with high cost performance and hand them over to his assistants. Part of the outsourcing fund will also be given as a bonus.

Generally speaking, these outsourcing projects are not very difficult. A research team of three assistants can do it in a month or two.And this kind of good thing is also the turn of several assistants. This time, it was hull's turn.

The project was outsourced by a new financial company.

Cheng Nuo confidently checked the customer's requirements.

In short, customers hope that they can create a model for financial chaotic system, which includes linear control of deposit interest rate, investment demand, and financial comprehensive linear control.

Very simple modeling work. In terms of difficulty, I'm afraid it's only one level higher than the modeling contest.

It won't take him a month.

”How long have you been working on this project?” Cheng Nuo asked.

”Twenty five days!” Henry replied with pride.

25 days, two-thirds of the schedule, or three people?

Cheng Nuo remained silent and did not speak.

Because he was afraid of being beaten if he said it.

Cheng Nuo continues to listen to hull's modeling ideas.

The so-called financial chaotic system refers to the randomness of the financial system itself. This concept was put forward in havermo's economic growth equation by stuze, an American economist.

System instability, bifurcation, and then with the help of the method of financial system mathematical model, to achieve the control of this financial system.

Hull's three modeling ideas are also very conventional.

Firstly, a financial system composed of production sub block, currency sub block, securities sub block and labor sub block is established by using the method of system dynamics.

Such a system, due to its irregular behavior and extreme sensitivity to initial state values and parameter changes, produces the above-mentioned chaotic phenomenon.

Then refining and simplifying, let X be the interest rate, the investment demand y and the price index Z. according to the relationship between the above three, we can get the following equation:
