Research On Evaluation Of Lean Production Level Of Rail Transport Equipment Based On WeChat Platform

With the increasing popularity of Chinese rail transport products in the international market,the rail transport equipment manufacturing industry has developed rapidly.However,the traditional batch production mode can not meet the needs of the market.Enterprises have begun to implement lean production.Therefore,it is necessary to evaluate lean production level of enterprises.In view of this,this paper relies on the user base of We Chat public platform and its convenient user experience.And in order to improve the evaluation efficiency and accelerate the promotion of lean production,the evaluation system of lean production level which based on We Chat public platform will be set up.Then the production efficiency of enterprises will be improved and the competitiveness of enterprises will be enhanced.Firstly,the paper makes a field investigation on the domestic largescale railway transit equipment manufacturing enterprises such as Dalian locomotive company and other companies.By studying on the characteristics of railway transit equipment manufacturing industry,after a preliminary draft,anonymous feedback,repeated summary process,a set of evaluation index system about the department of equipment,quality,logistics,process,production and human resources will be set up by the Delphi method.Secondly,after analyzing the advantages and disadvantages of Delphi method,analytic hierarchy process,principal component analysis and fuzzy clustering analysis,the analytic hierarchy process is used to calculate the weight value of each evaluation index.Then we build a scientific evaluation index weight system.Thirdly,after analyzing the user roles and their needs,the overall design of the functional modules of WeChat platform is carried out.Then the modules and functions of the platform are determined.On this basis,the evaluation system in detail will be designed by using PHP assembly language and MySQL database,including the front evaluation module and background management module.Then the custom menu,manual and automatic reply,the function of WeChat public platform are developed.Finally,the evaluation system will be applied on a company.Then the evaluation results of the system will be used to analyze the drawbacks of enterprises,and the improved measures will be put forward expediently.At last,the obtained conclusions are recognized by the enterprise experts.
