Research On Selection Of Sourcing Strategy For Urban Rail Transit Vehicle Equipment

With the rapid development of urban rail transit,the problem of poor economy has become more and more obvious,and it has received extensive attention from the whole society.The procurement of vehicle equipment and the maintenance during the life cycle are a large amount of continuous expenditure in urban rail transit projects.If the life cycle cost of vehicle equipment can be effectively reduced,the current situation of urban rail projects that cannot make ends meet can be alleviated to a certain extent..In order to achieve the goal of reducing the life-cycle cost of vehicle equipment,the urban rail industry has gradually carried out a transformation from one-time procurement to long-term or even full-life-cycle procurement,in order to achieve "quantity" in exchange for "low price" through the transformation of procurement strategy.A win-win situation.In order to explore the gap between the two procurement strategies,this article conducts research on the following core questions: Can a long-term procurement strategy achieve better economics than a one-time procurement strategy? What prerequisites are needed to achieve better economy? What is the impact of the change in procurement strategy on other aspects of the project besides economics? Can the transformation be carried out based on the current economic and industry environment?In the research on procurement strategy of the urban rail industry,most of the existing researches only focus on the concept and composition of life cycle cost,and occasionally involve qualitative analysis of influencing factors related to life cycle cost,but quantitative analysis of the two strategies And the analysis of the advantages and disadvantages of combining the status quo is rarely discussed.The feature of this article is to creatively apply the life cycle cost theory to vehicle equipment procurement,combined with project economic evaluation theory and industry characteristics,establish models and compare and analyze the emerging procurement strategies and traditional procurement strategies of urban rail transit vehicle equipment.,And put forward suggestions for improvement on the strategy selection in the follow-up procurement.The research idea of this paper is to establish the life cycle cost model of vehicle equipment through theoretical analysis combined with the characteristics of the urban rail industry,using the life cycle cost theory.Then,with reference to the domestic economic environment and current industry rules in recent years,the two important factors affecting equipment life and discount rate were evaluated and predicted,and the current costing formula and correlation coefficient were obtained.On this basis,this article fully considers the current status of procurement in the industry,analyzes and compares common one-off procurement strategies and long-term procurement strategies in terms of economy,risk,applicability,etc.,and combines actual data to compare The analysis of the two procurement strategies is upgraded to a quantitative level,and the effect,feasibility and implementation conditions of the long-term procurement strategy are summarized and prospected.The evaluation results show that if the economic environment,industry status and price system can still maintain the status quo,then from the economic point of view,the long-term procurement strategy has certain advantages compared with the one-off procurement strategy,but due to the current forecast of the external environment or The impact of the social environment on the cost is in a state of exploration,and the degree of mastery of the performance of the vehicle equipment itself still needs to be strengthened,so the risk of adopting a long-term procurement strategy is extremely high.The above-mentioned research shows that the current industry’s research on the mode of action and intensity of vehicle equipment affected by the social and economic environment is still shallow,and the long-term operational performance of vehicle equipment has not been fully grasped.Overall,it is currently not ready for a comprehensive transformation.,Still need more operational data and more in-depth theoretical research.
