【摘要】：復(fù)雜產(chǎn)品制造業(yè)是一國(guó)綜合實(shí)力的重要體現(xiàn),它的競(jìng)爭(zhēng)力關(guān)乎國(guó)力的興衰。復(fù)雜產(chǎn)品具有客戶需求復(fù)雜、組成結(jié)構(gòu)復(fù)雜、產(chǎn)品技術(shù)復(fù)雜、生產(chǎn)制造復(fù)雜等一系列特征。補(bǔ)貨問(wèn)題是復(fù)雜產(chǎn)品生產(chǎn)組織的一個(gè)重要方面,補(bǔ)貨管理的好壞,直接關(guān)乎生產(chǎn)能否順利進(jìn)行,成本能否得到合理控制,因而是非常值得關(guān)注的�；诖�,本文就復(fù)雜產(chǎn)品的協(xié)同補(bǔ)貨問(wèn)題展開(kāi)研究。 本文研究了“三供應(yīng)商——單制造商”組成的兩級(jí)供應(yīng)鏈在需求不確定的情況下的協(xié)同補(bǔ)貨問(wèn)題,提出了三種補(bǔ)貨策略并對(duì)比分析了不同策略下補(bǔ)貨批量和供應(yīng)鏈成本變化情況。主要研究?jī)?nèi)容如下： (1)通過(guò)對(duì)國(guó)內(nèi)外文獻(xiàn)和相關(guān)理論研究明確了供應(yīng)鏈協(xié)同補(bǔ)貨的研究現(xiàn)狀,得出Supply-hub是一種先進(jìn)的庫(kù)存管理模式,將其運(yùn)用到復(fù)雜產(chǎn)品生產(chǎn)物料的管理中可以提高補(bǔ)貨協(xié)同水平。 (2)詳細(xì)分析了本文要研究的問(wèn)題。界定了復(fù)雜產(chǎn)品的內(nèi)涵、特點(diǎn),對(duì)復(fù)雜產(chǎn)品生產(chǎn)所需物料的特性、需求不確定的原因、補(bǔ)貨要求進(jìn)行分析,總結(jié)出要準(zhǔn)時(shí)補(bǔ)貨、按所需量補(bǔ)貨、成套補(bǔ)貨。 (3)構(gòu)建了三種補(bǔ)貨策略模型并進(jìn)行了分析求解。在產(chǎn)品需求獨(dú)立且服從正態(tài)分布,補(bǔ)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(kù)存策略等前提下,分別構(gòu)建了供應(yīng)商獨(dú)立補(bǔ)貨、不考慮批量及時(shí)間協(xié)同和考慮批量及時(shí)間協(xié)同的三種補(bǔ)貨策略模型。模型以供應(yīng)鏈總成本最低為優(yōu)化目標(biāo),通過(guò)運(yùn)算證得,當(dāng)滿足一定條件時(shí),三種補(bǔ)貨策略均存在最優(yōu)解,且不考慮批量及時(shí)間協(xié)同的補(bǔ)貨策略供應(yīng)鏈成本總是低于供應(yīng)商獨(dú)立補(bǔ)貨策略下的成本。最后通過(guò)算例對(duì)三種補(bǔ)貨策略進(jìn)行了驗(yàn)證分析,得出,三種補(bǔ)貨策略中,并不存在一種補(bǔ)貨策略絕對(duì)優(yōu)于其它兩種策略,最優(yōu)補(bǔ)貨策略的確定要依據(jù)供應(yīng)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.
