5.3.2.5 Penentuan Prioritas Urutan Pemasok Gula Murni dengan TOPSIS
Technique for Order Preference by Similarity to Ideal Solution
Dalam penentuan prioritas urutan pemasok dengan TOPSIS terlebih dahulu dilakukan perhitungan bobot untuk masing-masing kriteria dan alternatif
dengan menggunakan rata-rata geometrik. Nilai rata-rata geometrik ini dianggap sebagai hasil penilaian kelompok dari nilai-nilai yang diberikan oleh 7 orang
responden. Berikut ini adalah contoh perhitungan rata-rata geometrik untuk alternatif 1 dengan subkriteria 1.
Responden 1 : 2,1852 Responden 2 : 4,3168
Responden 3 : 2,1852 Responden 4 : 3,3159
Responden 5 : 3,3159 Responden 6 : 3,3159
Responden 7 : 2,1852 Maka rata-rata geometriknya adalah :
X =
7 7
3 2
1
X ...
X X
X ×
× ×

X =

1852 ,
2 ...
1852 ,
2 3168
, 4
1852 ,
2 ×
× ×
× = 1,5429
Dengan cara yang sama, rata-rata geometrik setiap kriteria dengan alternatif. Rata-rata geometriknya dapat dilihat pada Tabel 5.16 berikut.
