【摘要】：随着市场竞争不断加剧，客户个性化需求日趋明显，客户已不仅仅满足从市场购买到标准产品。这就使得生产多样性、不可预见性、生产变更等现象频繁出现，，传统刚性生产计划管理正面临着严重挑战。因此，为客户提供定制化产品及服务的大批量定制生产模式应运而生。它要求企业制造系统具备一定的柔性，以应对市场不可预测的快速变化。生产计划作为制造企业生产管理的主要内容，生产系统是否顺畅，产能安排是否合理等直接反映生产计划的合理性。因此，大批量定制生产模式下柔性生产计划研究是企业竞争取胜的重要研究因素。为了有效解决竞争问题，有必要采用新方法和思想研究制定柔性的生产计划。通过研究发现大批量定制生产计划柔性的影响因素主要有产品结构树、设备生产能力、产品交货期等；建立了以提前/延期惩罚之和最小与生产工期最短为目标函数的设备能力规划模型，并对如何充分调度设备空闲时间的方法进行了研究，给出了基于交货期和S-I的设备空闲时间调度方法。根据产品结构树中零部件的生产装配约束关系，提出了支持柔性生产计划的任务元分解层次模型，并结合PERT理论，给出了各任务最早交货期的计算方法，建立了任务元属性与相关资源的逻辑映射模型，最终建立了通用件正向递推的生产计划模型以及定制件基于交货期逆向递推的生产计划模型，并提出了应对合同变更等突发状况的处理方法。上述模型及方法理论将为实现生产任务的合理分解以及加工设备的合理规划，提高设备利用率，提高生产计划的柔性及可控性，进而提高企业响应市场需求快速变化的能力提供理论参考。
[Abstract]:As the market competition intensifies, the customer's individuation demand becomes more and more obvious, and the customer is not only satisfied with the purchase from the market to the standard product. This makes the production diversity, unpredictable, production changes and other phenomena occur frequently, traditional rigid production planning management is facing serious challenges. Therefore, the mass customization production mode of providing customized products and services for customers came into being. It requires the enterprise manufacturing system to have certain flexibility to cope with the unpredictable rapid changes in the market. Production planning, as the main content of production management in manufacturing enterprises, directly reflects the rationality of production planning, such as whether the production system is smooth, and whether the production capacity arrangement is reasonable. Therefore, the research of flexible production planning in mass customization production mode is an important research factor for enterprises to win the competition. In order to solve the competition problem effectively, it is necessary to adopt new methods and ideas to make flexible production plan. Through the research, it is found that the main factors affecting the flexibility of mass customization production plan are product structure tree, equipment production capacity, product delivery time and so on. Based on the objective function of the sum of advance / delay penalty and the shortest production period, the capacity planning model of equipment is established, and the method of how to schedule the idle time of equipment is studied. An idle time scheduling method based on due date and S-I is presented. According to the production and assembly constraints of parts in the product structure tree, a task element decomposition hierarchy model supporting flexible production planning is proposed, and the calculation method of the earliest due date of each task is given based on PERT theory. The logical mapping model of task meta-attribute and related resources is established. Finally, the production planning model based on forward recursion of universal parts and the production planning model based on reverse recursion of delivery date are established. At the same time, it puts forward the methods to deal with the unexpected situation such as contract change. The above model and method theory will realize the reasonable decomposition of production tasks and the reasonable planning of processing equipment, improve the utilization ratio of equipment, and improve the flexibility and controllability of production planning. Then improve the ability of enterprises to respond to the rapid changes in market demand to provide a theoretical reference.
