Kalau yang disebut dimensi kelima itu adalah uncertainty dalam artian stochastic uncertainty, multi-realization atau multi-scenario rasanya hampir semua software punya cara untuk menanganinya. Jadi ndak baru-baru amat lah. Yang sampai saat ini (setahu saya) belum ada adalah cara atau paket yang menggabungkan uncertainty dari level yang berbeda: static-dynamic sampai ke economic (Merak/Teras) secara terintegrasi.
