Research On The Procurement Strategy Of C'City Metro Based On Material Classification

With the rapid development of urban rail transit,the subway operation safety will be more and more important,the subway operation materials in a timely manner and efficiently supply security requirements also more and more high,and the reasonable,scientific and effective purchasing strategy is to implement the subway material support one of the important conditions.Opened to traffic as the C city metro line 3,\"?\",word formal formation of rail transit network backbone,line subnetted operation of material support of the demand is higher and higher,if the continuation of the existing material purchasing strategy thinking,is bound to increase the procurement cost,and even endanger the subway operation safety.Therefore,the subway material purchasing strategy optimization study is imperative.To C city metro procurement strategy for scientific and comprehensive optimization research,in this paper,on the basis of the review of domestic and foreign research data,through learning and classification of the four quadrants of the grey system theory,analyses the characteristics of C city subway supplies and procurement status quo,put forward in C city subway in purchasing management supply timely,management cost is high,the quality difference between supply and demand big restricting purchasing management problems,such as,selecting the four quadrant method for material classification and grey system method of purchasing strategy optimization design,through the combination of quantitative and qualitative evaluation index,select the optimal purchasing scheme,in order to obtain the optimal procurement effect.Selected the subway signal system of professional supplies as a strategic material for the case analysis and verified the effect of before and after the optimization,from the operating safety and reduce procurement costs demonstrates the scientific nature,rationality of the procurement strategy optimization,as well as with C city subway operating company development requirements in particular.According to C city subway material purchasing management requirements and research,the optimization of practical guiding significance to the research results of procurement strategy,and has been applied in 2016 C city subway of material purchasing,it not only improves the C city metro operation co.,LTD.,purchasing management efficiency,also for other subway company material purchasing management also has the reference significance.
