【摘要】：隨著我國(guó)工程機(jī)械舊件回收與再制造的產(chǎn)業(yè)化發(fā)展,回收與再制造閉環(huán)物流管理問(wèn)題日益得到重視。回收與再制造閉環(huán)物流的不確定性、結(jié)構(gòu)復(fù)雜的特點(diǎn),導(dǎo)致傳統(tǒng)的物流網(wǎng)絡(luò)和信息系統(tǒng)無(wú)法開(kāi)展工程機(jī)械產(chǎn)品物流活動(dòng),因此,對(duì)于工程機(jī)械舊件再制造閉環(huán)物流網(wǎng)絡(luò)的研究是十分必要的。本文首先分析工程機(jī)械舊件回收與再制造流程,提出了工程機(jī)械舊件再制造閉環(huán)物流網(wǎng)絡(luò)設(shè)計(jì)模型,該模型中新增的拆解組裝中心,將整機(jī)預(yù)拆解處理和整機(jī)組裝與零部件再制造活動(dòng)分開(kāi),各個(gè)設(shè)施功能細(xì)分的網(wǎng)絡(luò)結(jié)構(gòu)有助于工程機(jī)械舊件再制造物流系統(tǒng)以低成本的運(yùn)營(yíng)。在環(huán)境需求確定的前提下,放松約束后,采用遺傳算法求解該模型,對(duì)網(wǎng)絡(luò)結(jié)構(gòu)布局進(jìn)行設(shè)計(jì),同時(shí)對(duì)網(wǎng)絡(luò)結(jié)構(gòu)布局與回收率、設(shè)施容量的關(guān)系進(jìn)行分析與討論,案例分析驗(yàn)證該方法是可行的。針對(duì)閉環(huán)物流網(wǎng)絡(luò)設(shè)計(jì)中的高度不確定性影響,在確定性閉環(huán)物流網(wǎng)絡(luò)模型基礎(chǔ)之上,本文引用廣義區(qū)間理論建立不確定環(huán)境下閉環(huán)物流網(wǎng)絡(luò)模型,并利遺傳算法完成不確定環(huán)境下網(wǎng)絡(luò)結(jié)構(gòu)設(shè)計(jì)。并比較了Laplace比較準(zhǔn)則、樂(lè)觀比較準(zhǔn)則以及悲觀比較準(zhǔn)則對(duì)設(shè)計(jì)結(jié)果的影響,對(duì)于經(jīng)濟(jì)情況比較脆弱的時(shí),可以選擇樂(lè)觀比較準(zhǔn)則下的最優(yōu)選址策略。對(duì)于經(jīng)濟(jì)情況比較穩(wěn)定時(shí),決策者可以選擇Laplace比較準(zhǔn)則和悲觀比較準(zhǔn)則下的最優(yōu)選址策略。通過(guò)比較確定環(huán)境下和不確定環(huán)境下的閉環(huán)物流網(wǎng)絡(luò)結(jié)構(gòu),得出不確定環(huán)境下的閉環(huán)物流網(wǎng)絡(luò)結(jié)構(gòu)能夠抵抗輸入?yún)��?shù)的影響,該網(wǎng)絡(luò)布局優(yōu)于不確定環(huán)境下的物流網(wǎng)絡(luò)結(jié)構(gòu)。本文基于工程機(jī)械再制造閉環(huán)物流網(wǎng)絡(luò)決策模型,開(kāi)發(fā)了服務(wù)于工程機(jī)械舊件再制造閉環(huán)物流網(wǎng)絡(luò)結(jié)構(gòu)決策模塊,該模塊主要完成對(duì)設(shè)施點(diǎn)的管理以及支持決策者完成再制造閉環(huán)物流網(wǎng)絡(luò)設(shè)計(jì)的功能,為閉環(huán)物流網(wǎng)絡(luò)模型實(shí)際應(yīng)用提供了有利的決策工具。
[Abstract]:With the industrial development of recycling and remanufacturing of used parts of construction machinery in China, the closed-loop logistics management of recycling and remanufacturing has been paid more and more attention. Because of the uncertainty and complex structure of closed-loop logistics for recycling and remanufacturing, traditional logistics networks and information systems are unable to carry out logistics activities of construction machinery products. It is necessary to study the closed-loop logistics network for the remanufacturing of old parts of construction machinery. In this paper, the process of recycling and remanufacturing of old parts of construction machinery is analyzed, and a closed-loop logistics network design model for remanufacturing of used parts of construction machinery is proposed. The pre-disassembly and assembly of the whole machine are separated from the remanufacturing activities of the parts and components. The network structure of the subdivision of each facility function is helpful to the operation of the remanufacturing logistics system of the old parts of the construction machinery at low cost. Under the premise of determining the environmental requirements, the genetic algorithm is used to solve the model, and the network structure layout is designed. The relationship between the network structure layout and the recovery rate and the facility capacity is analyzed and discussed. The case study shows that this method is feasible. Aiming at the influence of high uncertainty in the design of closed-loop logistics network, based on the deterministic closed-loop logistics network model, this paper uses the generalized interval theory to establish the closed-loop logistics network model in uncertain environment. Parallel genetic algorithm (GA) is used to design the network structure in uncertain environment. The effects of Laplace comparison criterion, optimistic comparison criterion and pessimistic comparison criterion on the design results are compared. When the economic situation is relatively weak, the optimal location strategy under the optimistic comparison criterion can be chosen. When the economic situation is relatively stable, the decision makers can choose the optimal location selection strategy under the Laplace comparison criterion and the pessimistic comparison criterion. By comparing the closed-loop logistics network structure in the uncertain environment and the uncertain environment, it is concluded that the closed-loop logistics network structure in the uncertain environment can resist the influence of input parameters, and the network layout is better than that in the uncertain environment. Based on the closed-loop logistics network decision model for remanufacturing of construction machinery, this paper develops a decision-making module of closed-loop logistics network structure serving for the remanufacturing of old parts of construction machinery. This module mainly completes the function of managing the facility point and supporting the decision makers to complete the design of the remanufacturing closed-loop logistics network, which provides a favorable decision-making tool for the practical application of the closed-loop logistics network model.
