Comprehensive Evaluation of Car-Body Light-Weighting Scheme Based on LCC Theory
Accounting Department, Business School, Central South University, China
In this paper, a comprehensive evaluation model of light-weighting scheme is established, which is based on three dimensions, including the life cycle costs of the resource consumed by the designed objects (LCC), willingness to pay for the environmental effect of resource consumption (WTP) and performance (P). Firstly, cost of each stage is determined. Then, based on the resource classification, which is based on cost elements, determine the material list needed, and apply WTP weight coefficient to monetize life cycle environmental impact and obtain the life cycle comprehensive cost of designed scheme (TCC). In the next step Performance (P) index is calculated to measure the value of the life cycle costs by applying AHP and SAW method, integrated (TCC) and (P) to achieve comprehensive evaluation of light-weighting scheme. Finally, the effectiveness of the evaluation model is verified by the example of car engine hood.
