6.2 Saran
Berdasarkan pengalaman dalam dalam pembuatan sistem pengambilan keputusan dengan metode AHP ini, terdapat beberapa saran yang diberikan oleh penyusun terkait dengan pengembangan sistem ini. Saran-saran tersebut di antaranya adalah:
a. Aplikasi sistem pendukung keputusan pemilihan Obyek wisata di Kota Surabaya ini dapat dikembangkan lebih lanjut dengan menambah kriteria yang lain sebagai penelitiannya serta menambah jumlah obyek wisata yang ada di Kota Surabaya.
b. Sistem pengambilan keputusan ini dapat di kembankan lebih lanjut mencapai ruang lingkup provinsi.
c. Sistem ini dapat dikembangkan dengan metode yang lebih komplek dan lebih akurat lagi. Seperti penggabungan 2 metode AHP (Analitycal Hierarshy
