Research of Grain Emergency Scheduling Problem Based on Particle Swarm Optimization

摘要

Grain Emergency Scheduling is a very important and practical research subject,Scheduling problems should regard not only its time effectiveness but also its economical effectiveness.According to the characteristics of grain emergency,establishing a more constraints grain emergency scheduling model,to consider constraints of emergency resource requirements,emergency time constraints and cost constraints,to optimize multi-objective of the earliest start time of emergency and the least number of rescue point.Using particle swarm optimization to solve and giving out the steps for solving as well,An example verifies the model's rationality,and the feasibility and the validity of using the ant colony optimization here.
