通过分析齿轮箱方案设计综合评价案例,建立机电产品方案设计的综合评价模型和方法,与同类文献区别在于对指标权重的理解与权重的确定方法不同。给出相对合理的方案排序方法,用同一案例说明评价过程,指出所论模型与方法适用于底层指标分级标准已知的机电产品方案设计的综合评价。 By analyzing the gearbox case design comprehensive evaluation case and establishing the comprehensive evaluation model and method of mechanical and electrical product scheme design, the difference from the same kind literature lies in the different methods of understanding the index weight and determining the weight. Gives a relatively reasonable way of sorting programs, and uses the same case to illustrate the evaluation process. It points out that the proposed models and methods are suitable for the comprehensive evaluation of the mechanical and electrical products design that is known by the bottom level standards.
