【摘要】：复杂产品制造业是一国综合实力的重要体现,它的竞争力关乎国力的兴衰。复杂产品具有客户需求复杂、组成结构复杂、产品技术复杂、生产制造复杂等一系列特征。补货问题是复杂产品生产组织的一个重要方面,补货管理的好坏,直接关乎生产能否顺利进行,成本能否得到合理控制,因而是非常值得关注的。基于此,本文就复杂产品的协同补货问题展开研究。本文研究了“三供应商——单制造商”组成的两级供应链在需求不确定的情况下的协同补货问题,提出了三种补货策略并对比分析了不同策略下补货批量和供应链成本变化情况。主要研究内容如下： (1)通过对国内外文献和相关理论研究明确了供应链协同补货的研究现状,得出Supply-hub是一种先进的库存管理模式,将其运用到复杂产品生产物料的管理中可以提高补货协同水平。 (2)详细分析了本文要研究的问题。界定了复杂产品的内涵、特点,对复杂产品生产所需物料的特性、需求不确定的原因、补货要求进行分析,总结出要准时补货、按所需量补货、成套补货。 (3)构建了三种补货策略模型并进行了分析求解。在产品需求独立且服从正态分布,补货提前期固定,制造商采用JIT生产,Supply-hub内采用连续检查库存策略等前提下,分别构建了供应商独立补货、不考虑批量及时间协同和考虑批量及时间协同的三种补货策略模型。模型以供应链总成本最低为优化目标,通过运算证得,当满足一定条件时,三种补货策略均存在最优解,且不考虑批量及时间协同的补货策略供应链成本总是低于供应商独立补货策略下的成本。最后通过算例对三种补货策略进行了验证分析,得出,三种补货策略中,并不存在一种补货策略绝对优于其它两种策略,最优补货策略的确定要依据供应链的具体情况。
[Abstract]:Complex product manufacturing industry is an important embodiment of a country's comprehensive strength, its competitiveness relates to the rise and fall of national strength. Complex products have a series of characteristics, such as complex customer demand, complex composition structure, complex product technology, complex manufacturing and so on. Replenishment is an important aspect of the production organization of complex products. The quality of restocking management is directly related to whether the production can be carried out smoothly and whether the cost can be controlled reasonably, so it is worth paying close attention to. Based on this, this paper studies the collaborative replenishment of complex products. In this paper, we study the collaborative replenishment problem of a two-level supply chain composed of "three-supplier single-manufacturer" in the case of uncertain demand. Three restocking strategies are put forward and the changes of replenishment batch and supply chain cost under different strategies are compared and analyzed. The main contents of the study are as follows: 1) based on the domestic and foreign literature and related theoretical research, this paper clarifies the research status of supply chain collaborative replenishment, and draws the conclusion that Supply-hub is an advanced inventory management mode, and its application to the management of complex products can improve the coordination level of replenishment. The problems to be studied in this paper are analyzed in detail. This paper defines the connotation and characteristics of complex products, analyzes the characteristics of materials needed for production of complex products, the reasons of uncertain demand, and the requirements of replenishment, and concludes that the goods should be replenished on time, replenished according to the required quantity, and replenished in complete sets. Three models of replenishment strategy are constructed and analyzed. Under the premise of independent product demand, normal distribution of service, fixed replenishment lead time and continuous inspection inventory strategy in JIT production, the independent replenishment of suppliers was constructed. Three replenishment strategy models which do not consider batch and time cooperation and consider batch and time cooperation. The model takes the lowest total cost of the supply chain as the optimization goal. It is proved by calculation that when certain conditions are satisfied, the three replenishment strategies all have the optimal solution. Supply chain cost is always lower than that under supplier independent replenishment strategy. Finally, through the verification and analysis of the three replenishment strategies, it is concluded that there is not one replenishment strategy that is absolutely superior to the other two strategies, and the optimal replenishment strategy should be determined according to the specific conditions of the supply chain.
