大批量定制产品成本估算服务模型

为了满足企业在产品生命周期内不同阶段对成本估算的应用需求,引入服务的概念,提出了大批量定制产品成本估算服务模型;建立了定制参数赋权、相似实例组提取、指数平滑预测等元服务;通过对元服务的编排组合,实现了成本粗略估算、成本快速估算、成本实时估算和成本精确计算等业务流程服务,分别适应客户初步询价、合同最终报价、产品成本控制和企业利润核算等应用需求;构造了合同报价辅助决策图供企业报价参考。最后以桥式起重机产品的成本估算为例,给出了详细的实现步骤,
说明方法的有效性。

Cost Estimation Service Model of Product in Mass Customization

Aimed to satisfy the manufactories’ needs of cost estimation at different periods in mass customization,a cost estimation service model of product in mass customization was proposed.Several atomic services including dynamic weights assignment algorithm,similar instance group matching,exponential smoothing algorithm were established,and composite services like coarse cost estimation,rapid cost estimation,real-time cost estimation,accurate cost analysis were also put forward.These services were assembled piecemeal in the application systems,such as rapid quoting for customer,final order quoting,cost control,profit calculation.Assistant decision chart for final quoting of new customization products was also presented.The proposed methodology demonstrates the effectiveness in an instance of cost estimation of an overhead traveling crane product.
