Object Orientation and Operational Research
开发了一个混合整数规划模型，用于城市固体废物系统中多种副产品的回收规划，可在微机上求解，并通过假设城市案例展示了该方法的实用性。
Material recycling is quickly becoming the most visible component of municipal solid waste management systems, and optimization models could play a prominent role in the long-term cost-effective planning of these systems. In this paper, we develop a mixed integer programming model for the recycling of various by-product materials within the overall waste system. This model is solvable on a microcomputer for reasonable problem dimensions, and the planning methodology is applied to a hypothetical municipality to illustrate the potential utility of the developed modelling approach.
