考虑再利用需求的垃圾回收处理优化模型

垃圾回收处理是建设资源节约和环境友好形社会(即两型社会)的基本要求.本文利用逆向物流管理优化方法研究带确定性日回收垃圾处理问题,对经过垃圾处理中心处理过后的垃圾分全部或部分可被再利用两种情形，建立了垃圾回收相关企业成本最小的约束优化模型.该模型是0-1整数规划模型，能够直接在LINGO软件平台上求解.应用实例验证了模型的效用.

Optimization Model of Garbage Collection with Recycling Demand

It is a fundamental requirement to recycle garbage for construction of resource conserving and environmental friendly society (called two types of social). This article investigated the problem of garbage collection with deterministic daily recycled amount by the approach of optimal inverse logistics management. The optimization models were constructed respectively with minimal processing cost in two cases: the processed garbage can be fully reused by shipping to the demand enterprises directly, or the processed garbage can be partially reused by shipping to the demand enterprises or the garbage treatment centers. The models turn out to be 0-1 integer programs, and can be solved directly in the software LINGO. Case study shows that the models are promising.
