Applied Research, Based On The New The Pdca Ring Of Lean Production

WY LAMPS CO., LTD. is a small-sized and private-owned manufacturing enterpriselocated on south Jinagsu province, which specializes in making diversified auto lamps andaccessories with a 30-year history. It has the bus lamps as its core-competitive product, andthe annual value of output approaches 12.5 millions RMB. With the more intensecompetition and easy entry of bus lamps market, the profit of the whole industry is gettingsmaller and smaller. For WY Company, how to keep in existence and development hasbeen the most important issue as facing so ruthless competition in this industry. Meanwhile,facing this industry with sensitive price, how to cut cost and eliminate waste the furthest ineach operation process including R&D, producing, quality control and so on under aguaranteed sale situation, which is the problem has to be resolved.Lean production is an acknowledged management concept, a complete set of methodand tool in the world, which has decreasing and eliminating waste as its core managementconcept. And large numbers of practices showed its distinct effect on cutting cost andincreasing efficiency.This paper is written against the WY Lamps manufacturing enterprise, which iscombined PDcA circle method with feedforward and feedback control system on field ofautomatic control theory, and implemented lean production reform on each productiveoperation process of WY Company through utilizing post-improved PDCA circle methodafter a deep analysis between auto parts manufacturing industry background and leanproduction theory. Finally, to combine a real implement process with effect, a conclusion isindicated to small and medium-sized enterprise in this paper: the lean production methodcan be appliedsmoothly and successfully in small-sized enterprise as long as to effectivelyimplement new PDCA circle on its each process.
