【摘要】：当今,经济全球化竞争日益增大，给企业带来机遇的同时也带来严峻的挑战。为了适应动态变化的市场需求，大多数企业转向多品种小批量的订货型生产模式，这种变化使得企业生产计划系统遇到了前所未有的挑战。企业必须制定合理的生产计划、不断缩短产品交货期、提高产品质量和服务水平，只有这样企业才能在竞争激烈的市场上立于不败之地。在多品种小批量生产环境下，建立合理有效的生产计划成为当生产运营领域研究和应用的热门话题。本文以多品种小批量订货型生产企业ZTY公司生产计划系统作为研究对象，对其生产计划体系和流程进行了详细的分析和改进研究。根据ZTY公司生产系统及产品订单特点，分析了目前公司生产计划管理存在的问题，并提出优化方案。具体包括两方面：第一,在离散型分段生产线上使用JIT和TOC相结合的管理思想指导生产计划，，以提高生产供应的灵活性；第二，在具体的生产计划方面，对订货型生产的订单选择和产量进行优化。针对ZTY公司生产计划系统应用需求预测方法、粗生产能力计算方法、作业排序法、经济订货模型法等方法提出了一系列改进策略，以达到降低库存管理成本，缩短对用户需求的响应时间，优化生产计划系统为目的。生产计划系统优化后，ZTY公司准时交货率提高了6%~10%，半成品库存量降低20%左右。
[Abstract]:Nowadays, the economic globalization competition is increasing day by day, brings the opportunity to the enterprise at the same time also brings the severe challenge. In order to adapt to the changing market demand, most enterprises turn to the multi-variety and small batch order-type production mode, which makes the enterprise production planning system encounter unprecedented challenges. Enterprises must make reasonable production plan, shorten the delivery time of products and improve the quality and service level of products. Only in this way can enterprises be in an invincible position in the competitive market. Under the environment of multi-variety and small batch production, it is a hot topic to establish a reasonable and effective production plan in the field of production and operation. This paper takes the production planning system of ZTY Company as the research object, and makes a detailed analysis and improvement on the production planning system and process of the production planning system of the multi-variety and small-batch production enterprise. According to the production system of ZTY Company and the characteristics of product order, this paper analyzes the problems existing in the production planning management of the company at present, and puts forward the optimization scheme. In order to improve the flexibility of production supply, the management idea of combining JIT and TOC is used to guide production planning in discrete segment production line. Second, in the specific production planning, order-based production order selection and production optimization. In order to reduce the cost of inventory management, a series of improvement strategies are put forward in order to reduce the cost of inventory management, aiming at the application of demand forecasting method, crude production capacity calculation method, job scheduling method, economic ordering model method and so on in the production planning system of ZTY Company. Shorten the response time to user demand, optimize the production planning system for the purpose. After the optimization of the production planning system, ZTY's on-time delivery rate increased by 6% and 10%, and the stock of semi-finished products decreased by about 20%.
