Abstract
Abstract. Making a multi-attribute decision regarding the location of a swine farming facility is difficult because of the vagueness and uncertainty of the evaluation indicators. In this study, after the main factors affecting swine farming were considered, pork quality and the economic benefits of farming were analyzed. Twenty evaluation indicators were selected to establish an index for determining the location of a swine farming facility based on the analytic hierarchy process (AHP). The values of qualitative and quantitative indicators were normalized to construct a weighted standardized matrix. The application of grey correlation analysis and the technique for order preference by similarity to an ideal solution (TOPSIS) were applied to calculate the overall degree of closeness of each candidate site. The pros and cons of the candidate sites were sorted to construct a location decision model according to the size of the overall degree of closeness. The locations of existing Suqian swine farms were used to validate the location decision method. The result showed that the location decision model could obtain satisfactory results for determining the location of a swine farming facility. Keywords: AHP, Grey correlation, Location decision model, Swine farming location, TOPSIS.
