Hello everyone, I am Yu Tianren, and most of my friends call me "Old Ice". Today we talk about toyota motors suffering from cyber attacks. At the beginning of March, Toyota Motor Corporation ceased production at all 14 plants and 28 production lines in Japan. At the same time, two Hino Motor Co., Ltd., which are also part of the Toyota Group, and Daihatsu Motor Company's Kyoto plant also stopped production.
Toyota Motor Corp. said it had 13,000 vehicles affected, but also said production levels of 950,000 units in March and 8.5 million units for the full year would not be affected. Because there is only one day, it can be made up.
The reason for the suspension of production is that a supplier of automotive plastic parts called "Kojima Stamping Industry" has been attacked by a network attack, the company told the media, but the specific situation did not say, anyway, it seems that the company's homepage can not be logged on the evening of March 2.
After all, it is not a trivial matter that a cyber attack has caused a company as big as Toyota to stop production, and even alarmed the Minister of Economy, Trade and Industry Koichi Ogi, because this is a hybrid war, a manifestation of Hybrid War, which directly involves economic security, and now everyone says that economic security is also an important aspect of national security, of course, I don't know what conclusions will be made in the future.
There is no conclusion about that hybrid war, we can't talk about that, we can only go back and review whether Toyota itself has any problems. We know that Toyota is a very profitable car company, of course, now is not the most profitable, the most profitable is Tesla, but Toyota is still very capable of making money, at least the second right.
That is to say, Toyota's production efficiency is very high. We all know that efficiency and safety are a contradiction, and high efficiency is definitely low safety, and vice versa. From the narrow definition of safety is like this, we know that domestic rail transit, such as subway high-speed rail or whatever, must go through security checks, so that safety has been guaranteed, but some efficiency has been lost. In a broad sense, this statement still holds.
Like the "Toyota production method" has always been known as the most efficient production method, production efficiency to what extent, in the 90s of the last century, there was a period of Mazda car almost closed, and then was saved by Ford, at that time some Mazda cooperative factories can not do it to invest in the Toyota Group, the result of Toyota's guidance consultants went to Mazda people is fainted.
For example, Ha, when using a CNC machining center, sometimes to observe the situation inside the center, generally everyone is accustomed to using both hands to open two doors and take a look, but the Toyota Group's regulations are to open only one side of the door, because it can save zero points and a few seconds of time. Also, after the general parts are processed, everyone is used to blowing it with compressed air.
However, the Toyota Group's approach is not to blow immediately, but to slide along the track and then blow later, because this can recover more processing coolant. The Toyota Group is like this. Toyota is most famous for its JIT system, just in time, and the core of this system is zero inventory. Japanese auto companies basically only do the final product development and assembly, and basically all the parts are supplied by cooperative factories.
These Toyota's cooperative factories not only have to make these parts, but also send them to the specified place at the specified time, shuanggui, not early or late, in order to meet these conditions, sometimes the trucks of the cooperative factory will go around the Toyota factory, because what if there is an accident on the road if they do not arrive in advance? I arrived early and couldn't send it in, so I went around the assembly factory.
In this way, Toyota eliminates the warehousing link, not only saves the warehouse space, but also saves the cost of warehouse management, and also saves the interest of the parts procurement, which is calculated to the extreme. There is a saying that describes Toyota-style management: "Dry towel and then twist it", that is, I will hang you out of the water without water, which is the meaning.
But this zero inventory also has his problem, that is, once the supply chain is broken, what to do? That is to say, there is a problem with the safety of production, and this concern has always existed and there have really been problems. There was a highway tunnel accident in 1979, the Great Hanshin Earthquake in 1995, the Aisin Industrial Fire in 1997, and the Great East Japan Earthquake in 2011. Toyota has stopped production, this time is like this, the same source of accident, Hino and Daihatsu stopped production only one or two factories, while Toyota body is 14 factories and 28 lines are all stopped.
But will Toyota change the way JIT works because of these accidents? No. Because the probability of accidents is very small, more than a decade and a few decades, Toyota is willing to bear the loss of occasional suspension of production, but also to get the long-term efficient part of the benefits. We're going to talk about it today, thank you.
