Abstract: It is a traditional research problem to optimize the allocation and scheduling of resources.In practical engineering applications，the linear programming optimization models are usually established to minimize computing cost，but the optimal scheduling model is often difficult to solve under more variable multi-parameter constraint conditions.This paper deploys channels earth to build an earth optimal scheduling system based on the South-North Water Diversion Shandong section of the channel for more than one hundred kilometers of earth.Based on the distance of earth and optimal scheduling algorithm，the algorithm searches all of the same recent sub-scheduling to earth in order to achieve the priority objectives of minimum cost.Finally，an example demonstrates the effectiveness of the algorithm performance.The paper research algorithm has important reference value to study the related resources for optimal scheduling and allocation.
