PCIe bus enumeration

Is there any method for assigning PCIe bus fixed?

For example, my device pcie bus number is changed
when another pcie device is inserted.

I have a 4 same pcie device and i want to identify each device
according to the pci bus number (according to pcie slot they are 
inserted into).

When i change kernel boot parameter for kernel to assign the pci bus number,
the result was the same.

Is there any method for that?

Thanks in advance.
