中文摘要：

客户定制产品特点为按订单多品种、单件生产，如何设计拉动系统，提高产出并控制库存，快速响应客户需求是一大难题.为研究该类型产品的拉动系统设计，以暖通空调这一典型客户定制产品的制造为案例，采用价值流图（VSM）分析生产系统及关键业务流程，结合看板（Kanban）和固定在制品（Conwip）构建拉动生产系统，以 Arena 对生产流程及关键件采购流程仿真建模，选取输出指标建立目标函数，在不同的权重下以 OptQuest 优化拉动系统参数.系统的综合绩效提升15.5%～30.5%，拉动系统参数稳定，结果表明所设计的拉动系统可行、有效.

英文摘要：

The features of ETO products are multi-species but single production for each contract, how to design pull system,improve throughput and control WIP,response to customers＇demand quickly are big problems.To study the pull system which is designed for products of this kind,a HVAC manufacturing company was taken as the case since it is a typical ETO product,and the VSM was used to analyze the production system and critical business process,and the Kanban and Conwip were combined to build pull system.The production process and critical parts procurement process were simulated with Arena,and objective function was constituted with chosen output indexes.The parameters of the system were optimized with OptQuest under different weights.The overall performance of the systeme improves 15.5%~30.5%,and the parameters of pull system are steady.The results showed that the designed pull system is feasible and effective.
