According to our experience, after spending a lot of time studying these two processes in depth, we found that these two production methods have more in common than differences. Powertrain equipment still provides components for power generation. The body shop is still making all the panels. In order to make cars, the assembly plant still assembles all these parts together. In general, there is no real difference. Especially by automating the supply next to the production line, we can help the assembly line respond to changes. For example, when an electric car production line needs to switch from a large combustion-powered car to an electric car, we will send the correct components or parts to the point of use. All that is needed is the notification in the advanced software. Once the system or assembly line supervisor makes these clicks, we will respond and go to the appropriate location to pull the correct one. The delay is eliminated, and the probability of error occurrence is almost zero.
