Abstract

STUDY ON POST EVALUATION OF HIGH-SPEED RAILWAY BASED ON FAHP AND MATLAB SIMULATION CALCULATION Yongzhi Chang, Suocheng DongOriginal scientific paper Targeted at constructing a scientific post-evaluation system, this paper establishes 4 first indices, 9 secondary indices, and 32 third indices on the basis of post evaluation analysis of high-speed railway construction projects. With Harbin-Dalian High-speed Railway as the object of empirical analysis, the author builds a model through the fuzzy analytic hierarchy process (FAHP), and carries out simulation calculation with Matlab. Finally, the author draws the conclusions that Harbin-Dalian High-Speed Railway gets good results. Specifically, the routes selected by survey and design are appropriate, work safety is ensured during the construction, the project operation has stimulated the GDP, the per capita GNP of residents along the high-speed railway has increased, and people's satisfaction and willingness to participate in high-speed railway projects have been improved. Nevertheless, acoustic and radiation protection measures should be adopted to improve transport efficiency, increase project revenue, and reduce the environmental pollution caused by highspeed railway operation. Keywords: fuzzy analytic hierarchy process; high-speed railway construction project; Matlab; post evaluation Studija o naknadnom vrednovanju željeznice visoke brzine na temelju izračuna simulacije FAHP i MATLABIzvorni znanstveni članak Usmjeren na izgradnju znanstvenog sustava naknadne procjene, ovaj rad definira 4 prva indikatora, 9 drugih indikatora i 32 treća indikatora na temelju analize naknadne procjene projekata željezničkih pruga visokih brzina. S Harbin-Dalian željeznicom visoke brzine kao objektom empirijske analize, autor gradi model kroz neizraziti analitički hijerarhijski proces (FAHP) te provodi simulacijski izračun s Matlabom. Konačno, autor zaključuje da HarbinDalian željeznica velike brzine postiže dobre rezultate. Naime, prikladni su putovi odabrani anketom i projektom, tijekom izgradnje osigurana je sigurnost na radu, projekt je stimulirao BDP, porastao je BDP po glavi stanovnika duž željezničke pruge te zadovoljstvo i spremnost na sudjelovanje ljudi u željezničkim projektima viskokih brzina. Ipak, trebaju se usvojiti mjere zaštite od buke i zračenja radi poboljšanja učinkovitosti prijevoza, povećanja prihoda od projekta i smanjenja onečišćenja okoliša uzrokovanog željezničkim prometom visoke brzine.Ključne riječi: fuzzy analitički hijerarhijski proces; Matlab; post evaluacija; projekt izgradnje željeznice visoke brzine
