【摘要】：本文关注具有挤兑效应的设施选址-库存-定价问题，即在选址问题的基础上，同时考虑库存因素和定价决策对于选址问题的影响。新产品和再制造品同时存在于供应网络之中，假设它们具有依赖于价格的顾客需求；同时由于挤兑效应的引入，每个产品的需求不仅受到自身价格的影响，还受到另一种产品的影响，或者说新产品市场受到再制造品的挤兑。对于这样一个问题，本文的目的是对供应链网络进行收益管理，同时研究挤兑效应、定价决策和库存成本对于选址决策的影响，以及进一步探讨，挤兑效应是如何影响供应网络结构、物流流动和相关决策的，不同的挤兑方式，又会对网络结构产生怎样的影响。对于该设施选址-库存-定价问题，本文建立了一个数学模型，并分别将这个模型应用于简单挤兑和倒U型挤兑的情况。简单挤兑中挤兑系数固定不变，不受两种产品价格比值的影响，考虑到实际情况中再制造品价格对于它市场竞争力的重要作用，本文又考虑了倒U型挤兑的情况，在这种情况中，挤兑效应系数随着再制造品比新产品价格折扣的增加呈现倒U型。通过离散化价格和不等式变换，本文最终建立了一个圆锥二次混合整数规划，在求解过程中，通过添加扩展多维拟阵不等式来提高模型求解效率。本文的最后一部分通过数值实验和对结果的分析验证了模型和算法的有效性；对是否考虑挤兑效应的结果进行了比较，结果表明考虑挤兑效应的情况其总收益会高于未考虑挤兑效应的模型；并分别针对简单挤兑模型和倒U性挤兑模型分析了其中挤兑效应的影响。对于简单挤兑模型，通过从小到大改变挤兑系数取值，发现挤兑系数的提高使得决策价格和总收益有所提高，并改变配送决策；对于倒U型模型，，通过给定再制造品价格的方式，发现对于递增的折扣策略，总收益呈倒U型改变，选址和配送策略也随之变化。
[Abstract]:This paper focuses on the facility location-stock-pricing problem with run effect, that is, based on the site-selection problem, the influence of inventory factors and pricing decision on the location problem is taken into account.New products and remanufactured goods exist simultaneously in supply networks, assuming that they have price-dependent customer demand, and that the demand for each product is affected not only by its own price, but also by the introduction of the run effect.It is also affected by another product, or a run on the market for new manufactured goods.For such a problem, the purpose of this paper is to manage the revenue of the supply chain network, at the same time to study the effect of run on, pricing decision and inventory cost on the location decision, as well as further study.How does the effect of the run affect the network structure of supply, the flow of logistics and the decision making, and how does the different run mode affect the network structure?For the location-stock-pricing problem, a mathematical model is established and applied to simple and inverted U-type runs.In simple extrusion, the extrusion coefficient is fixed and is not affected by the price ratio of two kinds of products. Considering the important effect of the price of remanufactured goods on its market competitiveness in the actual situation, the inverted U-type run is considered in this paper.In this case, the coefficient of extrusion effect is inverted U-shaped as the price discount of remanufactured goods increases compared with the new product.In this paper, a conical quadratic mixed integer programming is established by discretization of price and inequality transformation. In the process of solving the problem, extended multi-dimensional matroid inequality is added to improve the efficiency of model solving.In the last part of this paper, the validity of the model and the algorithm is verified by numerical experiments and the analysis of the results.The results show that the total income of the model considering the effect of the extrusion is higher than that of the model without the effect of the extrusion, and the influence of the effect of the extrusion is analyzed based on the simple model and the inverted U-model respectively.For the simple extrusion model, by changing the value of the extrusion coefficient from small to large, it is found that the increase of the extrusion coefficient increases the decision price and total income, and changes the distribution decision.By giving the price of remanufactured goods, it is found that for the increasing discount strategy, the total income changes in the form of inverted U shape, and the location and distribution strategy also changes with it.
