Abstract

In this study, the objective is to analyze spatial potential of paddy logistics to a rice mill with Fuzzy Analytic Hierarchy Process (FAHP) and Geographic Information System (GIS). There were 3 factors adopted for this analysis: 1) distance from a rice mill, 2) distance from a main road, 3) distance from a minor road and yield. In term of specifying membership function of factors, data was divided into 4 levels of factor suitability; highly potential (S1), moderately potential (S2), low potential (S3) and lowest potential (N). Referring to experts, pairwise comparison was applied to compare importance of level of factor suitability. Subsequently, membership function was specified as Triangular Membership Function. Then, the map of potential surface was created by the method of Weight Overlay between access factor and product factor of Geographic Information System (GIS). According to the study of 8 districts (Amphoe) in northern part of Nakhon Ratchasima Province, the result demonstrated that high-level potential surface was mostly found in Amphoe Khong accounting for 48.57%, Amphoe Bua Yai 20.68%, and Amphoe Non Daeng 16.70%, respectively. Consequently, the outcome of this study could be adopted as data for planning and developing logistics management of paddy in order to be preparatory for a logistics hub in the future.
