【摘要】:豐田召回事件使得豐田公司在2012年召回車輛總數(shù)高達(dá)500萬輛,并為此支付了史上最昂貴的11億美元召回費(fèi)用。但風(fēng)波并未平息,大眾、本田等公司先后也陸續(xù)宣布在各個(gè)國家召回其大量的缺陷汽車。從2013年11月25日,大眾中國啟動國內(nèi)最大規(guī)模的汽車召回行動,640309輛搭載7速雙離合變速器的車輛因電路故障召回,207778輛進(jìn)口途威和國產(chǎn)途觀因車燈故障召回。這是繼3月份召回38萬輛問題汽車后,大眾再次實(shí)施DSG車型的大規(guī)模召回。在當(dāng)今這個(gè)產(chǎn)品研發(fā)周期日益縮短,更新?lián)Q代更為頻繁的時(shí)代,產(chǎn)品質(zhì)量的問題更為凸顯,汽車召回成為一個(gè)常態(tài)性問題。在各國消費(fèi)者以及各國法律的壓力下,更多汽車制造型企業(yè)采取對其缺陷產(chǎn)品的召回行動,并為汽車召回的真?zhèn)過程支付了高昂的召回費(fèi)用。 本文在總結(jié)了國內(nèi)外學(xué)者對汽車召回研究以及對時(shí)間成本研究的基礎(chǔ)上,通過大量走訪汽車企業(yè)、汽車維修站以及汽車運(yùn)輸企業(yè),對現(xiàn)實(shí)問題進(jìn)行了詳細(xì)的調(diào)查了解,最終通過數(shù)學(xué)建模的方式,在考慮召回過程中的時(shí)間成本的前提下,針對召回過程中產(chǎn)生的巨額成本進(jìn)行分析,建立了不同召回策略的召回成本模型。通過對汽車缺陷產(chǎn)品數(shù)量、自建修理廠的投資系數(shù),對第三方管理的管理成本系數(shù)、外包修理廠商的維修成本系數(shù),單位車輛維修基本費(fèi)用等變量對召回成本影響的研究,對比了不同召回策略產(chǎn)生的召回成本,進(jìn)行了最優(yōu)召回策略的決策分析。最后,通過調(diào)查所得的一些參數(shù)數(shù)據(jù),對模型進(jìn)行了檢驗(yàn)性運(yùn)算。 結(jié)果顯示,缺陷汽車數(shù)量較大,大于模型測算出的閾值時(shí),通過建立維修中心以及維修外包,可以降低召回成本;當(dāng)建立維修中心的初始投資成本較高、外包管理費(fèi)用較高,大于模型測算出的閾值時(shí),采用分銷渠道召回、返廠維修的方式,產(chǎn)生的召回成本更低;外包維修成本系數(shù)較高,,高于模型測算出的閾值時(shí),應(yīng)避免采用外包維修的方式進(jìn)行汽車召回。
[Abstract]:The recall brought the total number of vehicles recalled by Toyota to 5 million in 2012, paying the most expensive $1.1 billion recall in history. Honda and other companies have also announced recalls of a large number of defective cars in various countries. Since November 25th 2013, Volkswagen China has launched the largest recall in China. 640309 vehicles carrying a 7-speed double clutch transmission have been recalled for circuit problems. The recall of 207,778 imported Tuwei and domestic Touguan due to lamp failure followed a recall of 380,000 defective vehicles on March. VW is once again carrying out large-scale recalls of DSG models. In this era of shorter product development cycles and more frequent upgrades, product quality problems have become even more acute. Automobile recall has become a normal problem. Under the pressure of consumers and laws of different countries, more automakers have taken recall action on their defective products and paid high recall fees for the whole process of automobile recall. On the basis of summing up the domestic and foreign scholars' research on automobile recall and time cost, this paper makes a detailed investigation and understanding of the practical problems through a large number of visits to automobile enterprises, car repair stations and automobile transportation enterprises. Finally, by mathematical modeling, considering the time cost in the recall process, the huge cost generated in the recall process is analyzed. The recall cost model of different recall strategies is established. Through the number of defective automobile products, the investment coefficient of self-built repair factory, the management cost coefficient of the third party management, the maintenance cost coefficient of the outsourced repair manufacturer, the recall cost model of different recall strategy is established. This paper studies the effect of basic cost of unit vehicle maintenance and other variables on recall cost, compares the recall cost generated by different recall strategies, and makes a decision analysis of the optimal recall strategy. Finally, some parameter data are obtained through the investigation. The model is tested. The results show that when the number of defective vehicles is larger than the threshold calculated by the model, the cost of recall can be reduced by establishing maintenance center and outsourcing, and when the initial investment cost of establishing maintenance center is high, the cost of outsourcing management is higher. When the threshold is larger than the threshold calculated by the model, the cost of recall is lower when the distribution channel is recalled, and the cost of outsourced maintenance is higher than the threshold calculated by the model, and the cost of outsourcing is higher than the threshold calculated by the model. Car recalls should be avoided by outsourcing maintenance.
