AHProcess
Ruby gem that provides a way to create Analytic Hierarchy Process decissions with ease.
Installation
Add this line to your application's Gemfile:
gem 'ahprocess'And then execute:
$ bundle
Or install it yourself as:
$ gem install ahprocess
Usage
If you want to make a decision with AHP method just use decide static method of AHProcess:
decision_matricies = [[[1, 1.0/5],
[5, 1]],
[[1, 7],
[1.0/7, 1]],
[[1, 5],
[1.0/5, 1]]]
criteria_matrix = [[ 1, 7, 1.0/3],
[1.0/7, 1, 1.0/5],
[ 3, 5, 1]]
no_decisions = 2
AHProcess.decide(decision_matricies, criteria_matrix, no_decisions)
# => [0.6150850856622971, 0.384914914337703]You can also create consistency ratio for your parameters if you want to check if your matricies are consistent.
AHProcess.consistency_ratios(decision_matricies, AHProcess::RandomConsistencyIndexTable.index(no_decisions), criteria_matrix)
# => [[0.0, 0.0, 0.0], 0.31263038528636483]Contributing
