Optimization of Railway Mixed Goods Loading Layout considering Stability
Algorithm 1
Mixed goods classification algorithm.
Input mixed goods set ;
Output heavy goods set , middle goods set , light goods set 。
(1)
Arrange the goods set in descending order according to the weight of class//If the weight is the same, the goods with fewer classes will be ranked first, the same as below
(2)
Take the former // as the total number of goods
(3)
The former goods are ranked as in descending order of class density
(4)
Find so that the class density of is greater than , and get the set
(5)
Delete the goods contained in from
(6)
Arrange the remaining goods in in descending order by category volume
(7)
// as the quantity of the remaining goods except heavy goods
(8)
The goods of the former category are arranged in descending order of class density as
(9)
Find so that the class density of is greater than , and get the set
(10)
Delete the goods contained in and from
(11)
The remaining goods in are arranged in descending order according to class density to obtain set
