【摘要】:閉環(huán)供應(yīng)鏈管理已成為我國踐行可持續(xù)發(fā)展的重要環(huán)節(jié)。關(guān)于閉環(huán)供應(yīng)鏈管理中生產(chǎn)決策的研究,對制造企業(yè)如何在保護(hù)環(huán)境的前提下通過提高資源重復(fù)利用率來發(fā)展循環(huán)經(jīng)濟(jì)具有重要的現(xiàn)實(shí)意義,對實(shí)現(xiàn)我國“工業(yè)4.0計劃”也具有推動作用。分析閉環(huán)供應(yīng)鏈中不同情形下的生產(chǎn)決策問題,研究制造企業(yè)在各情形下的產(chǎn)能分配決策,有利于提高企業(yè)自身的競爭力和促進(jìn)循環(huán)經(jīng)濟(jì)的發(fā)展。論文首先介紹了閉環(huán)供應(yīng)鏈管理及生產(chǎn)決策的相關(guān)內(nèi)容,在寡頭壟斷市場競爭環(huán)境下,通過利用博弈論和拉格朗日乘子法進(jìn)行建模,討論了制造商和再制造商在兩階段中的最優(yōu)生產(chǎn)計劃?偨Y(jié)了再制造品生產(chǎn)計劃與價值折扣、廢舊產(chǎn)品回收率之間的關(guān)系。為制造企業(yè)結(jié)合自身實(shí)際情況合理分配新產(chǎn)品、再制造產(chǎn)品的生產(chǎn)計劃提供參照。其次,針對產(chǎn)品具有單向替代性情形下的閉環(huán)供應(yīng)鏈生產(chǎn)決策問題,運(yùn)用替代性理論,以制造商自身利潤最大化為目標(biāo)構(gòu)建兩階段閉環(huán)定價、生產(chǎn)計劃模型,研究制造商在考慮新產(chǎn)品對再制造產(chǎn)品具有單向替代情形下的最優(yōu)定價和生產(chǎn)數(shù)量問題。在這一基礎(chǔ)上利用數(shù)值仿真,分析替代性參數(shù)的變化對于定價和生產(chǎn)數(shù)量的影響,最終提出制造商應(yīng)采用何種替代措施將有利于提高企業(yè)總體利潤的建議。再次,針對產(chǎn)品具有雙向替代性情形下的閉環(huán)供應(yīng)鏈生產(chǎn)決策問題,利用產(chǎn)品間的相互需求替代性綜合考慮新產(chǎn)品和再制造產(chǎn)品相互替代的四種情況并建立以利潤為目標(biāo)的生產(chǎn)計劃模型,研究了制造商在該情形下的最優(yōu)生產(chǎn)決策。在此基礎(chǔ)上結(jié)合數(shù)值仿真,分析了制造商的最優(yōu)生產(chǎn)量與兩種產(chǎn)品之間替代性參數(shù)的關(guān)系,提出適用于制造商同時生產(chǎn)具替代性新產(chǎn)品和再制造產(chǎn)品時的生產(chǎn)決策建議。隨著循環(huán)經(jīng)濟(jì)發(fā)展模式在我國的不斷推進(jìn),對閉環(huán)供應(yīng)鏈中生產(chǎn)決策問題的研究將從更多角度、更深層次的方面對其進(jìn)行開展,探尋以更加符合實(shí)情的研究為我國制造企業(yè)的綠色發(fā)展提供可行性建議。
[Abstract]:Closed-loop supply chain management has become an important link in the practice of sustainable development in China. The research on production decision making in closed-loop supply chain management is of great practical significance to manufacturing enterprises how to develop circular economy by improving the resource reuse ratio under the premise of protecting the environment. It can also promote the realization of China's "Industry 4.0 Plan". This paper analyzes the production decision problem in different situations of closed-loop supply chain, and studies the decision of production capacity distribution of manufacturing enterprises under different circumstances, which is helpful to improve the competitiveness of enterprises and promote the development of circular economy. Firstly, the paper introduces the related contents of closed-loop supply chain management and production decision. Under the environment of oligopoly market competition, the model is modeled by using game theory and Lagrange multiplier method. The optimal production plan of manufacturer and re-manufacturer in two stages is discussed. The relationship between the production plan of remanufactured products, the value discount and the recovery rate of waste products is summarized. It provides reference for manufacturing enterprises to reasonably distribute new products and remanufacture products according to their own actual conditions. Secondly, aiming at the production decision problem of closed-loop supply chain under the condition of one-way substitution, a two-stage closed-loop pricing and production planning model is constructed with the goal of maximizing the manufacturer's own profit by using the substitution theory. This paper deals with the optimal pricing and quantity of remanufactured products under the condition of one-way substitution of new products. On this basis, numerical simulation is used to analyze the influence of the change of alternative parameters on the pricing and quantity of production. Finally, the suggestion that what kind of alternative measures should be adopted by manufacturers will be helpful to increase the overall profit of enterprises is put forward. Thirdly, aiming at the closed-loop supply chain production decision problem with two-way substitution, Taking into account the four situations of new products and remanufactured products replacing each other, a profit oriented production planning model is established to study the optimal production decision of manufacturers in this case. On the basis of the numerical simulation, the relationship between the optimal production of the manufacturer and the alternative parameters between the two products is analyzed, and the production decision suggestions suitable for the manufacturer to produce both new and remanufactured products are put forward. With the development of circular economy in our country, the research of production decision-making in closed-loop supply chain will be carried out from more angles and deeper aspects. To explore more in line with the reality of the study for the green development of Chinese manufacturing enterprises to provide feasible advice.
