Research On The Lean Development Tactic Of Dongan Automatic Transmission

Toyota's lean thinking is reflected not only in the production process,but also in the product development and sales service system.In terms of lean production,Dong 'an Automobile Research and development center's has been implementing mitsubishi management mode for many years,and has achieved lean production in the production process.In sales and service,Dong 'an has been customer-oriented and market-oriented,constantly improving the level and ability of sales and service,and have established a relatively complete sales and service system under the lean thinking.In the process of product development,dong 'an has been accustomed to importing products and technologies from mitsubishi corporation of Japan for localization,but has not realized the whole value stream lean product development of the development process.Although it effectively reduces the development work,only some adaptive development can be done in product development,and the independent development ability is weak,so the product development ability needs to be improved urgently.This paper summarizes the concept and theory development of lean development and research status at home and abroad,and analyzes the development process,status quo and existing problems of Dong 'an development.Oriented by problems,this paper puts forward the respect development tactic of Dong 'an auto automatic transmission,and constructs the guarantee measures to implement the tactic.The paper found that in the process of Dong 'an auto automatic transmission development,there are mainly three prominent problems: long development cycle,high development cost and product cost.Aiming at the above problems,this paper puts forward lean development strategies from three aspects on plan management,cost management and cost design: by setting reasonable working hours and margins and making rational overall planning,a scientific product development cycle evaluation system is established to shorten the development cycle and standardize the cycle management.Through cross-functional team collaboration,improvement of core engineering management and accumulation of fault data,unnecessary waste of analysis and verification can be reduced,so that the development process can not only effectively verify the design scheme,but also significantly reduce the development cost.Through parts benchmarking,cost analysis,multi-scheme design and value engineering application,the knowledge engineering system of engineers is constructed to effectively reduce product cost.n order to realize the smooth implementation of the above strategies,this paper puts forward guarantee measures from three aspects of process optimization,system optimization and cultural construction.The research of this paper supports the lean development of Dong 'an auto automatic transmission,reduces all kinds of waste in the process of product development,reduces development cost and product cost while improving product quality,and improves the core competitiveness of Dong 'an.
