Mengukur Konsistensi Kriteria (AHP)
Matriks Perbandingan Kriteria

Pertama-tama menyusun hirarki dimana diawali dengan tujuan, kriteria dan alternatif-alternatif lokasi pada tingkat paling bawah. Selanjutnya menetapkan perbandingan berpasangan antara kriteria-kriteria dalam bentuk matrik. Nilai diagonal matrik untuk perbandingan suatu elemen dengan elemen itu sendiri diisi dengan bilangan (1) sedangkan isi nilai perbandingan antara (1) sampai dengan (9) kebalikannya, kemudian dijumlahkan perkolom. Data matrik tersebut seperti terlihat pada tabel berikut.

Matriks Bobot Prioritas Kriteria

Setelah terbentuk matrik perbandingan maka dilihat bobot prioritas untuk perbandingan kriteria. Dengan cara membagi isi matriks perbandingan dengan jumlah kolom yang bersesuaian, kemudian menjumlahkan perbaris setelah itu hasil penjumlahan dibagi dengan banyaknya kriteria sehingga ditemukan bobot prioritas seperti terlihat pada berikut.

Matriks Konsistensi Kriteria

Untuk mengetahui konsisten matriks perbandingan dilakukan perkalian seluruh isi kolom matriks A perbandingan dengan bobot prioritas kriteria A, isi kolom B matriks perbandingan dengan bobot prioritas kriteria B dan seterusnya. Kemudian dijumlahkan setiap barisnya dan dibagi penjumlahan baris dengan bobot prioritas bersesuaian seperti terlihat pada tabel berikut.
