+ numbers for sequential operations are much shorter

+ numbers for sequential technologies are more intuitive

- harder to implement

- adding a operation in the middle of the tree can change half of its numbering

- numbers for technologies with many splits are less intuitive

Sequential technology example:

1
  2
    3
      4
        5
          ...
            20

Generation rules

If the last number of the parent operation is 1 like previous_numbers.1:

• and it has only one child operation, then the child operations number will be previous_numbers.2
• and it has multiple child operations, then the numbers of the child operations will be: previous_number.1.A.1, previous_number.1.B.1, previous_number.1.C.1, ...
