Optimization of Railway Mixed Goods Loading Layout considering Stability

Algorithm 3

General block construction algorithm (Taking heavy goods set as an example).

	Input heavy goods set , generate maximum number of blocks and effective volume ratio ;
	Output General block set 。
(1)	Initialize ,
(2)	，
(3)	while and
(4)
(5)	for block in each set
(6)	for block in each set
(7)	A new block is generated by lacing along the three axes of in all possible ways
(8)	If meets the criteria and there is no identical block in the , is put into
(9)	and the number does not exceed
(10)
(11)	return
