【摘要】：企业在新产品开发定位策略上的任何过失都会产生额外的供应链管理成本,作为新产品快速更新的汽车企业,若要以高效率、低成本、高品质的服务来满足下游订单的需求,不妨对产品的结构进行模块化、通用化的设计改进,以模块化组装的形式将产品成型时间往供应链下游进行推迟,从而定制出不同消费群体需要的产品,来减少或者消除供应链各阶段因预测累积起来的风险、满足客户的个性化需要和进行批量规划。本论文中,根据对相关延迟理论文献的研究和学习,针对SQ集团双品牌共平台策略发展的趋势,从供应链的全局角度进行企业的需求分析,并将研究重心更多地上移到了产品前期设计阶段,结合延迟策略及客户订单分离点的理论研究,认为通过对于汽车底盘中减振器和弹簧的通用化、模块化改进,在满足车型运动性和舒适性目标的前提下,供应链整体管理的成本也能够得到有效地提高;然后利用排队理论的思想将底盘供应链延迟的成本模型分为通用化生产和定制化生产两阶段,分别对应M/D/1和M/M/1模型;以通用化率θ作为客户订单分离点(CODP)的切入点来评估总成本模型的最佳解;根据计算的最优结果,将CODP设置在了减振器-弹簧生产流程中θ=0.68的位置,在这一节点,产品的通用化生产所占用的时间占到了接近70%,并通过控制减振器内部的各种阀片数量、尺寸上的选用和组合,配合不同参数的弹簧进行的分装,实现差异化定制。这一技术手段最终被证实产品的通用化率、库存成本等几个重要的经济效益指标有了显著的提高。
[Abstract]:Any negligence in the strategy of new product development and positioning will produce additional supply chain management costs. As an automobile enterprise which is quickly updated by new products, if we want to meet the demand of downstream orders with high efficiency, low cost and high quality service, the structure of the product may be modularized, the design improvement and the modular group are improved. In the form of loading, the formation time of the product is postponed to the downstream of the supply chain to customize the products required by different consumer groups to reduce or eliminate the cumulative risk of the supply chain at all stages of the supply chain and to meet the customer's personalized needs and batch planning. In this paper, the research and study of the related delay theory literature is based on this paper. In view of the trend of SQ group dual brand common platform strategy development, the demand analysis of the enterprise is carried out from the global point of view of supply chain, and the focus of the research is moved more to the stage of product design, combining the theory of delay strategy and customer order separation point. It is considered that through the generalization of the shock absorber and spring in the chassis, the model is considered. The cost of the overall management of the supply chain can be effectively improved on the premise of meeting the target of motor vehicle mobility and comfort, and then the cost model of the delay of the chassis supply chain is divided into two stages of general production and customized production using the idea of queuing theory, which correspond to the M/D/1 and M/M/1 models respectively; The best solution of the total cost model is evaluated as the breakthrough point of the customer order separation point (CODP). According to the optimal results, CODP is set in the position of theta =0.68 in the shock absorber spring production process. In this node, the time occupied by the product's general production is close to 70%, and the various valves inside the damper are controlled. The selection and combination of quantity, size, and combination with the spring of different parameters can achieve differential customization. This technical means is finally proved to be a significant improvement in several important economic benefit indexes, such as the universal rate of the product, the cost of inventory and so on.
