【摘要】：随着电子产品竞争的加剧,消费性连接器利润空间也进入微利时代。面对竞争,公司如何快速响应客户询价需求以及在开发初期进行准确的成本估算,对于提高公司的竞争力凸显的越来越重要。成本研究的最基本内容是成本估算,成本估算对项目的经济评价、成本的降低、新品的定价十分重要。因此,对连接器进行准确快速的成本估算应用研究很有意义。本课题研究了目前国内外对于成本估算现况,分析了产品设计的方法、类型和设计的过程,对设计特征的形成进行了阐述;分析了产品的成本构成以及设计对成本的影响,进而对产品成本估算方法进行了详细的分类和对比;结合公司连接器产品特点、生产模式、询价报价流程,确定了适合连接器成本估算的方法:参数成本估算法(PCE)。通过研究各种工艺的特点、生产过程,确定成本特征与产品的设计特征、制造特征和组装特征等关系模型,基于PCE法分别建立冲压件、电镀件、塑料件和组装参数成本估算模型。对各个模型中材料费、直接人工费、制造费、包装材料费等的估算进行了详细的论述。在运用这些具体的方法基础上,结合企业状况,本文提出了一个指导公司成本估算建模的标准流程。最后鉴于成本估算是公司的一项日常工作,选用Excel建立了冲压件、电镀件、塑料件和组装段的成本估算模板。估算模板减少报价计算量、规范公司对成本估算的方式、能够使设计人员输入不同参数即可进行成本优化,也为采购人员核对供应商报价的准确性以及为公司管理层选择自制还是外购提供了决策依据。
[Abstract]:With the intensification of electronic products competition, consumer connector profit space is also entering a small profit era. In the face of competition, it is more and more important for the company to respond quickly to customer's inquiry demand and to estimate the cost accurately in the early stage of development, which is more and more important to improve the competitiveness of the company. The most basic content of cost research is cost estimation. Cost estimation is very important to the economic evaluation of the project, the reduction of cost and the pricing of new products. Therefore, it is meaningful to study the application of accurate and fast cost estimation for connectors. This paper studies the current situation of cost estimation at home and abroad, analyzes the method, type and process of product design, expounds the formation of design features, analyzes the cost composition of product and the influence of design on cost. Then, the methods of product cost estimation are classified and compared in detail, and combining with the characteristics of connector products, production mode, inquiry and quotation process, the method suitable for cost estimation of connectors is determined: parametric cost estimation method (PCE).) By studying the characteristics of various processes, the production process, and determining the relationship models between cost characteristics and product design features, manufacturing features and assembly features, the stamping and electroplating parts were established based on PCE method. Cost estimation model of plastic parts and assembly parameters. The estimation of material cost, direct labor cost, manufacturing cost and packaging material cost in each model are discussed in detail. On the basis of these specific methods and combined with the situation of enterprises, this paper presents a standard process to guide the modeling of cost estimation. Finally, as cost estimation is a daily task of the company, Excel is used to establish cost estimation templates for stamping parts, electroplating parts, plastic parts and assembly sections. The estimate template reduces the amount of calculation of the quotation, standardizes the way the company estimates the cost, and enables the designer to input different parameters to optimize the cost. It also provides decision-making basis for purchasing staff to check the accuracy of supplier quotation and for management to choose self-made or outsourcing.
