“…In the latter, GIS are used as platforms, from which spatial analysis functions are used, and with which mathematical models are integrated to complete reservoir evaluation. In terms of mathematical models, fuzzy mathematics (Schrader, Balch, & Ruan, ; Taheri, ; Zoveidavianpoor, Samsuri, & Shadizadeh, ), gray clustering (Denney, ), artificial neural networks (Ahmadi, Saemi, & Asghari, ; Elshafei & Hamada, ; Wang, Wang, & Chen, ), gray multivariate correlation analysis (Naseri, Khishvand, & Sheikhloo, ; Shi, ), rough sets (Wu, Li, Dai, & Feng, ), support vector machines (Ahmadi, ), and geostatistical methods (Tamaki, Suzuki, Fujii, & Sato, ) are studied and/or integrated with GIS.…”
