The Application Of Lean Manufacturing In A Aerospace Enterprise

With the acceleration of global economic integration, the dramatic changes occur inthe competitive environment of our aerospace industry. From a global perspective, ourdomestic aerospace industry is still at the low level, there are some problem such as lowefficiency, long lead time and low first pass yield in the enterprise. We want to competewith the European advanced enterprise which has been in the world front, we have tochange all of the operation system. Lean manufacturing as an new and developing managemeasures has been widely extended. A enterprise want to shorten the lead time and reducethe manufacture cost through the promotion of lean manufacturing, finally improve theoverall competitiveness.The first chapter introduces the background and lean manufacture application indomestic and abroad aerospace company. The second chapter introduces lean manufactureorigination, definition and specification through the theoretical analysis. The third chapteranalyses lean manufacture feasibility in A company base on the current productionsituation. The fourth chapter introduces the cases of production management and qualitycontrol in A company. At the aspect of long lead time, make the analysis for the90daysproduction lead time of B787main landing gear brake rod, find out the root cause for timewaste. At the aspect of quality control, make the analysis for B787main landing gear bigparts boring out of tolerance, firstly find out the parts and location that occur the boringproblem frequently, second find out the6root cause. Regarding A320main landing gearbig parts low first pass yield, the lean manufacture experts find out the7root causethrough fishbone analysis. Afterward, the experts make the measures and makeimprovement gradually. A enterprise verify that lean manufacture play an important role toimprove production efficiency, shorten the lead time and improve pass rate, which canshare the experience with similar company.
