Research On Supplier Evaluation Of High Speed Railway Control Materials

With the rapid development of China's economy and the continuous progress of society,a large number of high-speed railways have been built in China.The successful construction and operation of high-speed railways indicate that China's railway has officially entered the high-speed rail era.The construction of high-speed railway project is expensive,in which the cost of material procurement accounts for more than 60%of the total cost.It is very important for the cost control to do a good job in the procurement management of materials.The construction of high-speed railway in China has a long history,in the construction period,quality requirements,the high speed railway material procurement put forward higher requirements,purchasing management is an important guarantee for the realization of high speed railway project schedule,quality and cost management objectives.Supplier is the upstream agent of material purchase and supply,and supplier selection is very important to engineering project.The material supplier into management areas,the implementation of control of supplier source,research on Evaluation and selection of qualified suppliers,to ensure the scientific and fair;performance for suppliers and objective analysis and evaluation,supervision and management of the timely and efficient completion of the contract,has the vital significance to the construction of high speed railway.This paper takes the supplier of a control material for high-speed railway as the research object,summarizes and analyzes the research status of supplier evaluation index and evaluation method at home and abroad.According to the high-speed railway construction is a material characteristics,combined with the evaluation index setting principles,of a material supplier in the performance evaluation and the influence factors were analyzed,a high speed railway a material supplier evaluation system index system of high speed railway and a material performance evaluation index,and each index of quantitative methods set.Then established the structure model of AHP,combined with 9 scale method to construct the evaluation of access and performance evaluation of the 22 judgment matrix,obtained through calculation,a control supplier evaluation index weight and the weight of material performance.Finally,the two evaluation systems are applied to evaluate the suppliers of CY high speed railway,and the scientific and advanced characteristics of the two systems are verified.
