【摘要】：随着纺织业大规模定制时代的到来,客户对纺织产品个性化定制程度和交货期可靠性要求的不断提高,袜业现行生产组织模式经常出现在制品积压和延迟交货的现象,同时由于外贸订单定制化程度高,不同订单难以实现共用,产品滞销风险大,业务部门在接单时往往比较保守,实际产能长期低于设计产能。针对这一问题,本文从纺织行业背景和织袜工艺特点入手,对某袜业纺织工业园外贸型订单代工企业多阶段生产组织模式中客户订单解耦点(Customer Order Decoupling Point,CODP)等问题进行了研究,并在此基础上分析了影响包装前缓冲区库存大小的因素,最后通过实验设计的方法进一步研究了各因素对包装前缓冲区库存成本的交互影响。首先,本文从某袜业纺织工业园生产组织模式的实际情况出发,通过对袜业工艺流程的分析确定了织袜过程的通用化和定制化环节,并论证了引入延迟生产策略的可行性和适用性,同时还发现传统研究对象中的流程型化工业和离散型装配制造业多为前端通用而后端定制的生产特点,与实际袜业两端定制而中间通用的生产特点有明显的不同,这也为本文最终提出袜业的三阶段生产组织模式奠定了基础。其次,在袜子成本归集研究的基础上,建立基于延迟生产策略的袜业三阶段生产组织模式的成本结构模型,并创新性的提出将袜业三阶段生产组织模式问题转化为“织缝-翻定”和“翻定-包装”两个两阶段问题以降低求解难度。同时根据袜业自身的生产工艺特点,改进了延迟生产结构的投资成本函数,使得成本模型更贴合袜业的生产实际,并通过CODP的定位研究得出包装环节为袜业实施延迟生产策略最佳工序的结论。最后,通过敏感性分析方法研究了服务率、订货周期、各样式包装数量、需求量均值、需求波动标准差对库存降低率的影响,得出在服务水平一定的情况下,当产品需求均值小、需求波动大时,基于延迟生产策略的袜业多阶段生产组织模式更优,同时发现随着产品种类的增多,延迟包装可降低对订货周期的要求。并在此结论的基础上,运用实验设计的方法进一步分析了安全库存水平、交货方式、库存盘点时间间隔、最大库存量对库存成本的交互作用,通过仿真实验验证了袜业三阶段生产组织模式的合理性和适用性,对袜业生产库存管理提供了新的借鉴和参考。
[Abstract]:With the arrival of mass customization era in textile industry, the customer's demand for customization degree and delivery time of textile products has been improved continuously. The current production organization mode of stockings industry often appears the phenomenon of overstocking and late delivery of goods. At the same time, because of the high degree of customization of foreign trade orders, different orders are difficult to be shared, the risk of unsalable products is large, the business departments are often conservative when receiving orders, and the actual capacity is lower than the design capacity for a long time. In order to solve this problem, this paper starts with the background of textile industry and the characteristics of hosiery technology, and studies the customer order decoupling point in the multi-stage production organization mode of foreign trade order contract enterprise in a textile industrial park of a certain stockings industry, such as customer order Decoupling Point (CODPP), and so on. On this basis, the factors that affect the inventory size of the pre-packaging buffer are analyzed. Finally, the interaction of each factor on the inventory cost of the pre-packaging buffer is further studied by the method of experimental design. First of all, based on the actual situation of the production organization model of a socks industry textile industrial park, through the analysis of the process flow of the socks industry, the general and customized links of the stockings process are determined. The feasibility and applicability of introducing delayed production strategy are demonstrated. At the same time, it is found that the process chemical industry and discrete assembly manufacturing industry in the traditional research objects are generally used in front and custom-made in the back end. It is obviously different from the actual stocking industry which is custom-made at both ends and generally used in the middle, which lays a foundation for this paper to finally put forward the three-stage production organization model of the stockings industry. Secondly, based on the research of socks cost collection, the cost structure model of three-stage production organization model of socks industry based on delayed production strategy is established. And innovatively put forward to transform the three-stage production organization model of socks industry into two stage problems: "knit-turn" and "flip-pack" in order to reduce the difficulty of solving the problem. At the same time, according to the characteristics of the stockings industry's own production process, the investment cost function of the delayed production structure is improved, which makes the cost model more suitable for the actual production of the stockings industry. Through the research of CODP, the conclusion is drawn that the best working procedure is to implement the delayed production strategy for the stockings industry. Finally, the effects of service rate, order period, packing quantity of each style, average demand and standard deviation of demand fluctuation on inventory reduction rate are studied by sensitivity analysis method. When the average value of product demand is small and the demand fluctuates greatly, the multi-stage production organization model of stockings industry based on delayed production strategy is better. It is also found that with the increase of product types, delay packaging can reduce the demand for ordering cycle. Based on this conclusion, the interaction of safety inventory level, delivery mode, inventory time interval and maximum inventory on inventory cost is further analyzed by the method of experimental design. The rationality and applicability of the three-stage production organization model of stockings industry are verified by simulation experiments, which provides a new reference and reference for stockings production inventory management.
