基于LINGO的带转运中心运输管理问题线性规划建模及求解

摘要

研究了多生产地、多销售地同时带多个中转站的运输转运问题，考虑了更符合实际的生产地和销售地也能作为中转站的情况，通过在中转站点中添加代表生产地和销售地的虚拟站点，得到求解该问题的虚拟转运网络图，进一步得到相应的线性规划模型，最后基于LINGO优化软件求解了一个运输转运问题实例，验证了模型的正确性。%In this paper, we studied the transportation problems with multiple places of production, places of sales and transshipment centers, considered the practical situation where some places of production and/or sales could act as transshipment centers, then obtained the corresponding virtual transshipment network chart and linear programming model, and at the end, performed an empirical study using the LINGO software.
