How to use

  • run(layers)

Parameters

layers : iterable, array, np.array

The structure of your AHP model (single layer or multi layer).

Example structure

  • Goal
  • Layer 1
    • Node 1
    • Node 2
    • Node 3
  • Layer 2
    • Node 1
    • Node 2
  • Alternatives Layer
    • Alternative 1
    • Alternative 2
    • Alternative 3
    • Alternative 4

Example of code

from stahp import stahp

print(stahp.run(
[
    [
        [1, .3, 5],
        [3, 1, 5],
        [.2, .2, 1]
    ],
    [
        [
            [1, .2],
            [5, 1]
        ],
        [
            [1, 3],
            [.3, 1]
        ],
        [
            [1, 4],
            [.25, 1]
        ]
    ],
    [
        [
            [1, 3, .25, 7],
            [.3, 1, .25, 7],
            [4, 4, 1, 9],
            [.14, .14, .11, 1]
        ],


        [
            [1, 3, .25, 7],
            [.3, 1, .25, 7],
            [4, 4, 1, 9],
            [.14, .14, .11, 1]
        ]
    ]
]
