Decision support systems are used in industry, to assist users in making decisions. Many methods are used in decision making, one of which is the Analytical Hierarchy Process (AHP). In this method, several layers can be used in decision making. This package has been designed to solve the AHP method with several 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]
        ]
    ],
