【摘要】：復雜產(chǎn)品制造業(yè)是一國綜合實力的重要體現(xiàn),它的競爭力關乎國力的興衰。復雜產(chǎn)品具有客戶需求復雜、組成結構復雜、產(chǎn)品技術復雜、生產(chǎn)制造復雜等一系列特征。補貨問題是復雜產(chǎn)品生產(chǎn)組織的一個重要方面,補貨管理的好壞,直接關乎生產(chǎn)能否順利進行,成本能否得到合理控制,因而是非常值得關注的。基于此,本文就復雜產(chǎn)品的協(xié)同補貨問題展開研究。 本文研究了“三供應商——單制造商”組成的兩級供應鏈在需求不確定的情況下的協(xié)同補貨問題,提出了三種補貨策略并對比分析了不同策略下補貨批量和供應鏈成本變化情況。主要研究內(nèi)容如下： (1)通過對國內(nèi)外文獻和相關理論研究明確了供應鏈協(xié)同補貨的研究現(xiàn)狀,得出Supply-hub是一種先進的庫存管理模式,將其運用到復雜產(chǎn)品生產(chǎn)物料的管理中可以提高補貨協(xié)同水平。 (2)詳細分析了本文要研究的問題。界定了復雜產(chǎn)品的內(nèi)涵、特點,對復雜產(chǎn)品生產(chǎn)所需物料的特性、需求不確定的原因、補貨要求進行分析,總結出要準時補貨、按所需量補貨、成套補貨。 (3)構建了三種補貨策略模型并進行了分析求解。在產(chǎn)品需求獨立且服從正態(tài)分布,補貨提前期固定,制造商采用JIT生產(chǎn),Supply-hub內(nèi)采用連續(xù)檢查庫存策略等前提下,分別構建了供應商獨立補貨、不考慮批量及時間協(xié)同和考慮批量及時間協(xié)同的三種補貨策略模型。模型以供應鏈總成本最低為優(yōu)化目標,通過運算證得,當滿足一定條件時,三種補貨策略均存在最優(yōu)解,且不考慮批量及時間協(xié)同的補貨策略供應鏈成本總是低于供應商獨立補貨策略下的成本。最后通過算例對三種補貨策略進行了驗證分析,得出,三種補貨策略中,并不存在一種補貨策略絕對優(yōu)于其它兩種策略,最優(yōu)補貨策略的確定要依據(jù)供應鏈的具體情況。
[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.
