Productivity Improvement Study About Microwave Oven’s Production Line Of WP Company

Micro Wave Oven(MWO)is one of home appliance series’ product and total average annually demanded by global market is about 75 millions to 80 millions,most of MWO are being supplied by two domestic home appliances giant manufacturer,they are Media and Galanz with OEM mehod.WP Corporation is a world well-known brand who own designing,manufacturing and sales function,its MWO products are fed to market with two mehods:OEM and self-made,one of the MWO sery product Microwave and Hood Combination(MHC)is self-made and selling in North America market.Due to the excellent cost-peformance and robust quality MHC product gain customers’ favorite,and anticipating the future market demanding will reach 2 millions per year,40% of total North America market annual amount 5 millions,but actual yearly output capacity of WP Coporation’s MWO manufacturing factory is 1.5 million,still have huge gap 500 thousands pieces by comparing to the demanding target.The thesis takes WP Corporation’s MWO manufacturing factory as researching object,to analyse the 500 thousands gap of final assembly output capacity and finding out the root cause is the output fluctuation.Thru systematically using theory and analyzing tools about4M1 E,learning curve,FMEA,line balance,economic motion principles,TWI-JI,data linear regression etc to identify and judge variable input factors of assembly process.Base on that to figure out solving and improving solutions for the issue of output fluctuation aim at enhancing productivity.The improving solutions were implemented internal as benchmark area,and then extending to the entire assembly workshop.Eventually the below outcomes were gained:Matching to the future market demanding target;increased average hourly output by people with 33.4%,line balance rate improved with 8.8% and reduced output fluctuation range from10.66% to 2.45%.The paper via the researching about WP Coporation’s MWO final assembly output capacity fluctuation for pursuing productivity improvement.Aim at identifying the improving opportunities and enchancing direction for the manufacturing ability.And to eliminate the waste during the manufacturing process as much as possible without adding extra labor,in pursuing of enhancing enterprise’s manufacturing ablity and cost competitive.Proactively establish well lean production platform for launching smart and manufacturing system in the future;also provide verified experience to other companies as a reference.
