【摘要】：中国加入WTO已经十年有余，其融入世界经济的步伐进一步加快，市场前景一片光明。但同时面对复杂多变的市场需求，面临的挑战也日益严峻。国内制造业虽然有高新技术的支持、雄厚的资金保障，但总的说来创造的综合效益不高。面对这样一个国际化、动态化的市场，采用先进的供应链管理(SCM)模式能够实现企业对市场做出快速响应和及时调整的要求，优化其生产运作过程，增强企业的核心竞争力，这是国内制造企业发展变革的方向与趋势。本文根据某医疗器械制造企业生产运作过程的实际情况展开研究，重点研究了供应链管理(SCM)下企业生产运作过程中生产调度及库存控制两个关键环节。利用Plant Simulation建立了这两类问题的仿真模型，通过仿真分析得到了相应的优化方案。本文完成的研究工作如下： (1)基于供应链管理的思想对核磁共振仪制造过程特点进行了分析研究，确定调度问题的类型及描述方法，提出了生产调度问题的数学模型及调度的目标函数；在仿真软件Plant Simulation中建立了调度问题的层式结构仿真模型，运用遗传算法对调度问题进行优化求解，得到了优化的调度方案。 (2)对产品的库存成本结构进行了分析，，提出了基于供应链管理思想的企业库存控制数学模型。通过定义采购成本将采购管理与库存控制联系起来，并通过仿真对比选择不同供应商时的库存成本，得到采购优化方案。在此基础之上，总结了影响库存成本的可变参数，并对这些因素进行实验设计，通过析因分析明确了相应因素对库存成本的影响程度，得到了优化的库存控制参数。 (3)对供应链管理思想下的企业生产运作模式进行探究，对准时生产制生产方式的进行了深入研究，阐述了看板控制系统的运行机制。运用仿真软件的Kanban控制对象，建立了核磁共振仪制造过程的看板控制系统模型。仿真结果显示，运用Kanban工具的无库存生产方式，大大降低了在制品库存水平。
[Abstract]:China joined WTO has more than ten years, its integration into the world economy to further accelerate the pace of the market has a bright future. But at the same time, facing the complicated and changeable market demand, the challenge has become more serious. Although the domestic manufacturing technology support, strong financial support, but generally not to create comprehensive benefits high. In the face of such an international, dynamic market, using the advanced supply chain management (SCM) model can realize the enterprise to make rapid response and timely adjustment of the requirements of the market, optimize the production process, enhance the core competitiveness of enterprises, which is the domestic manufacturing enterprise development direction and trend.
According to the actual situation of production and operation process of the enterprise of a medical device manufacturing research, focus on the supply chain management (SCM) production scheduling and inventory control of two key links in the process of production and operation of enterprise. Established the simulation model of the two kinds of problems by using Plant Simulation, through the simulation analysis, obtained the corresponding optimization scheme the research work of this paper is as follows:
(1) analyze the supply chain management of manufacturing process based on NMR characteristics, determine the type and description method of scheduling problem, the objective function of mathematical model and scheduling of production scheduling problem is put forward; in the simulation software Plant in Simulation layer structure simulation model of scheduling problem is established by using the genetic algorithm for solving the scheduling problem, optimized scheduling scheme is obtained.
(2) the inventory cost structure of products were analyzed, put forward the mathematical model of supply chain management based on enterprise inventory control. By defining the purchasing cost of procurement management and inventory control together, and through the simulation comparison different suppliers inventory cost, purchasing optimization scheme. On this basis, summarizes the influence the variable parameters of the inventory cost, and experimental design of these factors, through the factorial analysis defined the corresponding factors on the cost of inventory, the inventory control parameters optimization.
(3) the production and operation mode of supply chain management to explore, in-depth study of JIT production mode is carried out, expounds the operation mechanism of Kanban control system. Kanban control by simulation software, set up Kanban NMR instrument manufacturing process control system model. The simulation results show that no stock production using Kanban tools, greatly reducing the inventory level.
