Study on Logistic Path Optimization of Coal Based on Flow Efficiency

This paper introduced the index of resources flow efficiency to establish the coal resources flow network in production. The loss of coal resources, especially the resources quantity, the resources loss and the resources flow efficiency were quantitatively analyzed. Based on the enterprise practice of production and the fluctuation of quality-price ratio, we revised the formula of flow efficiency from the enterprise profit´s view, and constructed the optimization model of the coal logistic path. The coal was distributed on the high flow efficiency path which could get more value-added, and was essential for the coal-saving. Here we provided a scientific method and tool to solve the problem of the coal distribution and saving.
