在当今的经济管理工作中，经常会遇到物资调运问题，如电网供电调度。为了使其供电成本最少，编制供电计划，建立数学模型，采用运筹学所学的“最小元素法”，通过求解得出最优供电方案，并最终做出技术经济评估，使其电网布局更合理。
In today’s economic manage work, it always meet materials of allocate and transport problem. For example, the power supply bureau. In order to reduce the lost. We are the plan of the power supply, set up the model of the math, put to use the “method of the smallest element “get to the best plan of the supply electricity though those methods. At last, make the assess of techno-economics, to let the electrified wire netting assign more equitable.
