竞争环境下生鲜农产品转运网络优化设计

    An Optimization Design of Fresh Agricultural Goods Transport Network under Competition

    • 摘要: 针对生鲜农产品本身具有的易损特征及其承运企业竞争激烈的现实问题,考虑生鲜农产品易损性对需求量以及转运网络利润的影响,运用Stackelberg博弈思想构建生鲜农产品转运网络优化模型,并分析参与者在不同市场占有份额下如何根据对手现有网络布局做出自身利润最大化的选址决策。研究表明,在生鲜农产品转运网络优化设计中,生鲜农产品的易损性比传统转运网络的规模效应更能影响利润。在竞争环境下,转运中心数量的选择对垄断者和追随者争取利润最大化起着关键的作用。垄断者具有先入优势,决策者都应当根据实际市场环境做出最有利的网络构建优化决策。另外,在具有高易损因子的生鲜农产品运输中,追随者才相对容易进入市场。

       

      Abstract: In view of the perishability of fresh agricultural goods and the fierce competition of logistics enterprises, a hub network optimization model of fresh agricultural goods using the idea of Stackelberg game is constructed. In this model, the decaying factor which affects demand and enterprise profit is taken into consideration. And it provides an effective method for enterprises to make location decisions of maximizing their profits according to the existing network layout of the competitors. The results show that the perishability of fresh agricultural products has a greater impact on profits than the scale effect of traditional transport networks. Also, the number of hubs plays a key role in maximizing their profits in the competitive environment. Although the leader has a first-mover advantage, both decision makers should make the responsive optimization decisions according to the actual market environment. In addition, it is relatively easy for followers to enter the market when the decaying factor is high.
