The Research Of Urban Medical Waste Recycling Network Location-routing Optimization

With the advancing pace of socialist modernization, China's national economy and people's living standards have been huge developed. Medical industry is also flourishing, not only in raising the level of medical services but also in on the surge in the number of medical units, which makes the production of medical waste continue to increase the amount of medical waste disposal issue is particularly important. China is also on 4 June 2003 by the State Council executive meeting of the tenth of the "Medical Waste Management Regulations ", It clearly establishes a national focus on the implementation of safe disposal of medical waste, to encourage the safe disposal of medical waste technology research and development.Proof of the rapid development of modern logistics, with the object of logistics theory to a study of the flow system, strengthening management, improving economic efficiency has an important role. Logistics systems theory we study the medical waste collection, transportation system provides a new perspective and means. Therefore, recycling of medical waste from abroad advanced experience, combined with China's specific conditions, to establish and improve China's medical waste reverse logistics system for effectively preventing and controlling environmental pollution and promote recycling of medical waste, conserve resources, with very important.Now many of our large and medium cities have implemented a centralized medical waste harmless, but the level of treatment varies greatly, as a whole at a preliminary stage, the most important problems facing the treatment plant to the collection point is the selection of questions and points for the collection of Roving vehicle routing problem, this article Jinzhou District of Dalian City, was an example of medical waste recycling, construction site - the path dual objective decision making model, nested ant colony algorithm and genetic algorithm to solve Matlab program to obtain the system of science location decisions and vehicle routing decisions. The research can provide a reference for government departments and waste disposal companies.
