A Model for the Transportation of Hazardous Waste*
针对危险废物运输中信息不精确的问题，提出了一个结合精确与不精确信息的网络模型，并研究了其性质与求解方法。
ABSTRACT Many decision problems, such as the transportation of hazardous waste, can be modeled by networks. However, due to the imprecise nature of much of the information decision makers have available, it is sometimes difficult to determine a best approach to the problem. To alleviate this problem, a network model that combines both precise and imprecise information is presented for the transportation of hazardous waste. The properties of the network model are investigated and solution procedures are presented.
