First, from the parking point of view, it is obvious that the front of the car is facing the gate, and it is best to get in and out. So the first model to be considered is the placement facing the gate, and then the placement perpendicular to the gate is calculated (although I didn't calculate it, I think it is more reasonable to face the gate). As for how to model the cross delivery, I haven't decided yet. You can tell me if you know.
Second, in terms of use, it can be considered that 1 car and No.2 car can be used at the same time. Of course, the more the better. You can also consider the total use area of 1 and No.2 cars, which is more accurate (but from a practical point of view, it should be considered that 1 and No.2 cars can be parked at will, so,
The third point is the problem of leaving gaps in and out. Your PX is not clear, but it is also a distance. In this case, the minimum distance between two cars is 1000PX. There is a problem when unloading goods here. When the vehicle cannot be turned out, the blocked vehicle can be driven out of the garage first. That's the sentence. Can I think I can arrange them directly? You don't have to leave a passage like a normal parking lot? As long as the direct distance 1000PX? Because according to him, for example, the innermost car can't get out, so I have no access and can only pull out the door. Although I may lose all the cars in the parking lot every time, I meet the conditions of the highest utilization rate! In this case, there is not much computing space. According to theory, we can know this quantity. When the quantity is known, the Pareto Diagram will come out.
