Study On Engineering Change Management Of Elevator Company

The elevator is a kind of transportation that with People's Daily life closely.And it is the "special equipment" stipulated in the law,its design structure is complex,manufacturing accuracy requirement is very high,the installation process is rigorous,maintenance requirements specification;Compared to the general mechanical and electrical products,its performance more attention to security.There are all kinds of uncertain factors in the design process.Such as: customer demand changes,supplier delivery situation changes,quality problems caused by the design,all kinds of new technologies,to reduce the product cost and various deviations in the product manufacturing process.So,we need to make design change,and we also need to execute the change.Therefore,the Engineering Change should be a very important activity in the elevator manufacturing enterprises.For manufacturing companies,Engineering Change involves the all related functional departments of the company,involving the lifecycle of the product.It is a very important work in the enterprise research and development,design,production and all the business activities.Engineering Change can bring certain benefits to the enterprise,also is likely to cause certain loss to enterprise,how to accurately measure the pros and cons,make the right decisions,the Engineering Change management is very important.And the elevator company's engineering change management must pay more attention to the comprehensive measure of the quality of product,more should give full consideration to the elevator in the process of manufacture,installation,maintenance and use of relevant personnel safety may produce all kinds of effects.This paper based on the analysis of domestic and foreign needle lift company engineering change on the development of the first,the application of game theory,constructs the supplier,demand side,supervision of three party game model,and put forward five kinds of solutions,providing more options for solving this kind of problem;Secondly,based on the theory of engineering change,by the method of 5W1 H to the new design of the engineering change application form data system,and then through the mind map tool Mind Manager to use systematic engineering change data,standardization requirements,and ultimately improve the quality of the change;optimization of elevator enterprise engineering change process,data system and quality management the elevator system,construction of enterprise engineering conforms to our country national condition change management system;Finally,taking the XX elevator company as an example,the engineering change Workflow system is established,which can achieve a simple and efficient process management,data input and output,check the progress of the query,export summary statements,etc..The results show that the proposed game model and engineering change management system has a good effect.
