摘要
成本评估对于新产品开发有着重要意义。指出了目前参数成本评估对成本形成原因不能识别和反馈控制,对产品生产耗用资源的市场价格变动考虑不够充分的缺陷。依据作业成本法“产品消耗作业,作业消耗资源”的思想,从逻辑维、数据维、时间维三个维度建立了基于作业成本法的参数成本评估模型,并给出了运用质量屋确定主要评估参数的方法。运用径向基函数神经网络构建了作业评估关系(AER),并进行了案例分析。
Cost estimation plays an important role in new product development ; the two limitations in current parametric cost esti- mation are pointed out. Namely, the reasons of cost forming can not be identified, fed back and controlled, and the price fluctua- tion of resources market is not adequately considered. According to the ideas from activity - based costing that ＂products consume activities and activities consume resources＂, a three dimensional cost estimation model including logic dimension, data dimension and time dimension is established. The use of house of quality （HoQ） to estimate main parameters is discussed. Finally, the Radical Based Function （RBF） neural network is adopted to establish the Activity Estimation Relationships （AER） and an example of AER is given.
