【摘要】：在物流網(wǎng)絡(luò)中,配送中心是將供貨點(diǎn)與需求點(diǎn)緊密聯(lián)系在一起的重要橋梁。因此,配送中心的選址工作是物流系統(tǒng)分析中的一項(xiàng)核心內(nèi)容。配送中心的合理選址不僅對提高物流系統(tǒng)效益有著重要的作用,而且是物流系統(tǒng)規(guī)劃和整體優(yōu)化的戰(zhàn)略性決策問題。在現(xiàn)實(shí)生產(chǎn)經(jīng)營活動(dòng)中,選址區(qū)域內(nèi)已經(jīng)存在其他配送中心,此時(shí)進(jìn)入該區(qū)域選址必然要考慮競爭的影響。本文的論題正是基于這種情況而提出的。 本文首先介紹了論文選題的背景與意義,闡述了配送中心選址問題的國內(nèi)外研究現(xiàn)狀,接著對配送中心的概念及功能做了詳細(xì)的綜述。隨后對配送中心選址原則與影響因素進(jìn)行了分析,并總結(jié)出配送中心選址的現(xiàn)有方法。最后建立了有競爭的多配送中心選址模型并將改進(jìn)后的蟻群算法應(yīng)用于解決該問題。全文研究的主要內(nèi)容如下： (1)模型建立。在對無競爭的多配送中心選址的模型研究基礎(chǔ)上,考慮到競爭的影響,建立了有競爭的多配送中心選址模型。該模型考慮到競爭配送中心的存在,導(dǎo)致需求量的分配,綜合考慮了配送量與成本之間的相互影響。 (2)算法改進(jìn)。在對傳統(tǒng)蟻群算法的研究基礎(chǔ)上,針對傳統(tǒng)蟻群算法存在搜索時(shí)間過長以及易陷入局部最優(yōu)的缺點(diǎn),從信息素增量自適應(yīng)調(diào)整的角度出發(fā)進(jìn)行改進(jìn)算法,并驗(yàn)證其性能。 (3)實(shí)例應(yīng)用。以仿真算例為基礎(chǔ),將改進(jìn)的蟻群算法應(yīng)用到有競爭的多配送中心選址問題上。結(jié)果表明該模型能較好的處理有競爭的多配送中心選址問題且改進(jìn)的蟻群算法是合理有效的。 希望本文能對加深配送中心選址的了解與認(rèn)識(shí)起到幫助作用,對以后的研究起到參考作用。
[Abstract]:In the logistics network, the distribution center is an important bridge that connects the supply point with the demand point. The location of distribution center is a core content of logistics system analysis. The reasonable location of distribution center not only plays an important role in improving the benefit of logistics system, but also plays an important role in the analysis of logistics system. It is also a strategic decision problem for logistics system planning and overall optimization. In the actual production and operation activities, other distribution centers already exist in the location areas. The influence of competition must be taken into account when entering this region. The thesis of this paper is based on this kind of situation. This paper first introduces the background and significance of the selected topic of the paper, and expounds the domestic and foreign research status of the distribution center location problem. Then, the concept and function of distribution center are summarized in detail. Then, the principle and influencing factors of distribution center location are analyzed. Finally, the competitive multi-distribution center location model is established and the improved ant colony algorithm is applied to solve the problem. The main contents of this paper are as follows:. On the basis of the research on the location model of multi-distribution center without competition, considering the influence of competition, the model of multi-distribution center location with competition is established. This model takes into account the existence of competitive distribution center. The distribution of demand takes into account the interaction between distribution volume and cost. Based on the research of the traditional ant colony algorithm, aiming at the shortcomings of the traditional ant colony algorithm, such as long searching time and easy to fall into the local optimum, the improved algorithm is based on the adaptive adjustment of pheromone increment. And verify its performance. 3) case application. Based on a simulation example, The improved ant colony algorithm is applied to the competitive multi-distribution center location problem. The results show that the model can deal with the competitive multi-distribution center location problem and the improved ant colony algorithm is reasonable and effective. I hope this paper can help to deepen the understanding and understanding of distribution center location, and serve as a reference for future research.
