第三方物流参与限时蔬菜配送问题研究

根据我国第三方物流的发展现状，结合蔬菜运输企业的实际运营情况，建立一种有第三方物流企业参与的限时蔬菜配送模型。考虑配送成本及蔬菜配送的特殊性，对比有第三方物流企业参与的统一蔬菜配送与现阶段蔬菜配送的形式，采用RSG—GA混合算法对建立的模型进行求解。通过对比运算结果和运输时间的稳定性，分析第三方物流参与蔬菜配送问题的价值所在，探讨第三方物流在蔬菜配送问题中的影响及意义。

Research on the Third Party Logistics in Limit Vegetable Delivery Problems

According to the current development of the third party logistics, transportation and vegetables combined with the actu- al operations of the enterprise, the establishment of a third - party logistics enterprises to participate in the limit of vegetable dis- tribution model by considering the distribution of costs and vegetable distribution of particularity, there will be a third party uni- form distribution of vegetables and vegetable distribution stage in the form of logistics enterprises to participate in contrast to the use of RSG - GA hybrid algorithm to solve the model established by comparing the calculation results and the stability of the transport time. Value of third - party logistics involved in vegetable distribution of the problem is valued. And then the impact and significance of third - party logistics in vegetable distribution problems are explored.
