Study On Optimization Of China Compulsory Certification Testing Process In T Testing Laboratory

T Testing Laboratory is one of the major third-party vehicles testing institutions in China,which is also the first batch of national laboratories to conduct business on imported cars in Tianjin port.Nowadays,many new automobiles testing labs are established in the harbor by other national inspection centers.Therefore,the market competition in this port becomes fiercer.In order to meet the higher requirements from the market and picky customers,all the testing labs now have to improve their business more efficiently with higher quality.In that case,Laboratory Information Management System(LIMS)is introduced to help T lab to improve its management and solve problems from outside business environment.Then the T lab achieves the goal that the laboratory quality management system,including its procedures,runs well on LIMS.Nevertheless,T laboratory ignores a problem--a critical factor of which deeply affects the T lab’s competitiveness.Little progress is made after the implementation of LIMS.However,T laboratory still has chance to make great progress on its business process optimization.This thesis introduces current status of T testing laboratory’s CCC business on imported vehicles.Then the value stream mapping method was used to analyze the reason of the problems on both business acceptance process and testing process in the T lab.The results showed that the main process problems happened because of time consuming and redundant links though the samples registration process,so as that of low efficiency of sample information recording sheets and unbalanced producing(testing)line.The process improved plan was made according to the ECRS principles,the T lab should carry out measures to improve their process management,including strengthening its management on business plan,improving its process of sample management,eliminating its redundant links of the processes,and choosing a fixed position to paste its sample recording sheets.As a result,those methods was proved efficient in T testing lab.The overall time-consuming of business acceptance process reduced;the efficiency of information collecting and transferring were higher,and the value-added rate of the processes was higher than before.Production line balance,mountain plots and relevant methods were proved useful to tackle the problems.Production cycle in bottleneck station was reduced,and balance rate of the production line was improved.Finally,both the value-added rate and the production line balance rate of T lab increased by 17.26% and 115% separately,the maximum testing number of samples increased by more than 78% per day,while the minimum rate of equipment utilization in its workstation soared to 78%.Meanwhile,daily production costs was reduced,and the occupation of sample stored place was smaller than before.The business and testing processes of T laboratory achieve great improvement.The study is also proved to expand the application contexts of lean production and industrial engineering production management theories in third-party vehicles testing laboratories,which also has its reference significance for similar industrial product inspecting and testing institutions.
