Research On The Cost Estimating Meathod Of The Reducer Box Driven By Brand Factors

The competition among the reducer manufacturing enterprises is becoming more and more intense in recent years.It exists not only in quality and technology but also in product modeling and brand building.Shaping the brand image is an important way to improve the added value of the products and enhance the market competitiveness. The cost of the reducer box is influenced by its appearance changed with brand building. It is one of the important factors to make the decision to accept the change of the product modeling or not. Therefore, it is necessary to study the cost estimating method of the reducer box driven by brand factors. The main content of this dissertation is as follows.Some domestic and foreign well-known gear reducer boxes which carried brand characteristics are analysed.The whole life-cycle cost(WLCC) of the general reducer box is discussed. Besides, the Cycle cost, the creative cost, the pantent cost, the marginal cost and the brand effect are summed up from WLCC of reducer boxes.The mapping relationship between the brand features of reducer boxes and cycle cost, patent cost, ect. are studied. Corresponding mapping function is built, which lay the foundation for the cost estimation of the reducer box based on the influence of brand factors.Accounting cost analysis method based on the analogy estimation is put forward to estimate the cost of the reducer box which drived by brand factors, because the box function is invariant with the influence of brand characteristics. Then, the cycle cost, the creative cost, the patent cost, the marginal cost and the brand effect are analyzed one by one. The corresponding cost estimation models are constructed. The error sources of cost estimates and the error compensation method are analyzed qualitatively.The cost estimation system of the reducer box based on brand characteristics is developed with the tool of VB and access. First, the overall framework of the cost estimation system of the reducer box is built based on the feature of the brand, and the main function modules of the system are analyzed.The process of the cycle cost, the patent cost, the marginal cost and the brand effect of the reducer box is planned.Finally, the cost estimation system is verified feasibility and effectively by the R series reducer box which drived by brand features.
