【摘要】:隨著我國汽車產(chǎn)業(yè)的飛速發(fā)展,廢舊汽車的產(chǎn)生量也隨著逐年增加。因此,如何有效的對廢舊汽車進行回收、處理,并盡可能的提高汽車部件的利用率,減少對環(huán)境負(fù)效用的影響,實現(xiàn)資源的循環(huán)利用,這已成為我國汽車產(chǎn)業(yè)可持續(xù)發(fā)展的一個重要問題,同時也符合我國大力發(fā)展循環(huán)經(jīng)濟、建設(shè)節(jié)約型社會的現(xiàn)實目標(biāo)。國外部分發(fā)達(dá)國家的廢舊汽車回收產(chǎn)業(yè)相對成熟,而我國的廢舊汽車回收產(chǎn)業(yè)卻還處在初級階段,非正規(guī)的回收企業(yè)與非法的拆解處理公司是制約著我國廢舊汽車產(chǎn)業(yè)前進的重要因素。而對于政府控制著廢舊汽車回收的中國而言,如何合理的建立廢舊汽車回收網(wǎng)絡(luò)與選址實施方案,對于我國發(fā)展廢舊汽車產(chǎn)業(yè)與環(huán)境保護的可持續(xù)發(fā)展有著重要的意義。本文針對我國目前廢舊汽車逆向物流的現(xiàn)狀,站在政府的角度對一個區(qū)域內(nèi)廢舊汽車逆向物流網(wǎng)絡(luò)進行規(guī)劃。本文結(jié)合半期望設(shè)施選址理論,追求設(shè)施選址建造成本、運輸成本最小化與負(fù)效用函數(shù)最小化雙目標(biāo)模型。并在此基礎(chǔ)上,考慮了正向物流設(shè)施的擴建因素,分別在兩種情況下建立優(yōu)化模型。此外,由于廢舊汽車的回收量的不確定性影響,本文使用基于情景的魯棒方法求解模型,在廢舊汽車回收量不確定的情況下,分別構(gòu)建了上述兩個基本模型的魯棒模型,并用魯棒優(yōu)化方法求解。本文建立的模型均為混合整數(shù)線性規(guī)劃,全部使用IBM ILOG CPLEX 12.4平臺進行編程求解,并對結(jié)果進行仿真分析。
[Abstract]:With the rapid development of the automobile industry in our country, the output of the waste automobile is also increasing year by year. Therefore, how to effectively recycle and dispose the used automobile, and improve the utilization ratio of the automobile parts as much as possible, Reducing the negative impact on the environment and realizing the recycling of resources has become an important issue for the sustainable development of the automobile industry in China, and it is also in line with the vigorous development of circular economy in China. The realistic goal of building a conservation-oriented society. Some developed countries abroad have relatively mature recycling industries of used cars, while the recycling industry of used cars in China is still in its infancy. Informal recycling enterprises and illegal dismantling and processing companies are important factors restricting the development of China's used and used automobile industry. However, for China, where the government controls the recycling of used and used cars, How to set up the recycling network and the site selection scheme reasonably is of great significance for the sustainable development of the waste automobile industry and environmental protection in China. This paper aims at the current situation of reverse logistics of used and end-of-life vehicles in China. From the point of view of the government, the paper plans the reverse logistics network of used and used vehicles in a region. This paper, combined with the theory of semi-expected facility location, pursues the construction cost of facility location. Transportation cost minimization and negative utility function minimization are two objective models. On this basis, considering the expansion factors of forward logistics facilities, the optimization models are established in two cases. Because of the uncertainty of the recovery amount of the used and used vehicles, this paper uses the robust method based on scenario to solve the model, and constructs the robust models of the above two basic models in the case of the uncertainty of the recovery amount of the used and used vehicles. The models established in this paper are all mixed integer linear programming, all of which are solved by programming using IBM ILOG CPLEX 12.4 platform, and the results are simulated and analyzed.
