Evaluation for the Location Selection of Airport Based on WLSM-TOPSIS Method

Abstract:

It was a key procedure that the location selection of airport should be scientific and reasonable; this may make a great contribution towards the regional economic environment and also be very important to the construction of comprehensive transport system. So evaluation index system of the location selection of airport was based on technical indicators, economics, environmental impact and social significance. Experts adopted the weighted least-square method (WLSM) to calculate the weight of index. The linguistic variables figures were used to translate evaluation indexes from qualitative to quantitative, then the evaluation indexes of decision matrix was pooled and integrated. TOPSIS was introduced into this paper which can calculate the distance between two triangular fuzzy numbers. By calculating the distances to both the fuzzy positive-ideal solution and fuzzy negative-ideal solution synchronously, the degree of closeness was defined to estimate the ranking order of all alternatives. The scientific foundation for the decision-making of the location selection of airport had been provided by this mode.
