Research Development And Application Of Automobile Parts Purchasing Cost Control System

As the increasing competition in the automotive business, automobile competitive hasbeen changed from the product quality into the competitive between the quality andprice, which prices is a great the most impact of consumers, therefore, dropping theprice of automobile is quite important for the automobile enterprise. Lowerautomobile price through controlling automobile cost is the important way ofenhancing its competitiveness. Automobile enterprise parts procurement cost accountsfor75%of total cost of car, thus, lowering the price of procurement parts is quiteimportant for the price of automobile.Based the theoretical of procurement cost control, the paper analyzed and studiedthe constitution of procurement parts cost, proposed two method to controlautomobile parts procurement cost which is the automobile parts procurement costproportion computation and volume-price management, and applied methods to theX enterprise.Firstly, the paper analyzed the purpose and significance of automobile partsprocurement cost control from the setting of it, expounded the current studiedsituation of cost control and procurement cost control, and proposed the necessity ofcontrolling procurement cost.Secondly, the connotation of procurement cost control, the factor of procurementcost analysis and the primary affection factor of the procurement cost wereexpounded from the viewpoint of procurement cost control, and the paper analyzedthe major method the procurement cost control, and studied the mode of automobileparts procurement cost control, proposed the theoretical basis of automobile partsprocurement cost control.Thirdly, based the analyzing the cost constitution of the purchased parts of automobileenterprise, the paper established a model of parts procurement cost proportion; according to studyvariation of the increasing in the number of parts procurement, the price of parts raw material,worker wages and so on, the paper established volume-price management model, andexpounded the actual application state of automobile parts procurement cost proportion andvolume-price management.Fourthly, through the model of parts procurement cost proportion computationand volume-price which established above, the paper proposed demand analysis ofprocurement cost control system, and devised functional module of system, and developed system of cost proportion computation and volume-price management.Finally, the paper expound procurement cost control current situation of Xenterprise, analyzed its procurement cost control, and introduced the realization ofprocurement cost control system. Then, one model of the system is applied andachieved good results.The paper had the very strong operation effect and the instruction significancefor parts procurement cost control of auto industry, the results can be automaticallyanalyzed parts cost structure. It could intuitively reflect the true profit margins ofsuppliers, and also could directly measure the procurement price and the limit ofdropped price after the increase of quantity and a series of change of material price.
