摘 要:
为有助于在环境和经济框架内评价垃圾填埋场选址决策，本文建立了关于该问题的多目标模型，模型中既考虑了安置和运营设施需要的固定成本和可变成本，也考虑了居民区承受的风险，以及各居民区承担风险的公平性。并进一步讨论了用模糊方法处理的一般多目标规划模型的模糊最优解与有效解及弱有效解之间的关系。最后使用两种模糊目标规划方法求解数值例子以分析所建模型的适用性，结果表明，加权模糊方法可以为决策者提供更接近期望值的满意方案。[著者文摘]

A Fuzzy Multiobjective Model for Locating Landfills

Abstract:
This paper develops a multiobjective model for determining locations of landfills in the hope of helping solve the problem in the framework of environment and economy. The objectives considered are minimization of the total cost and the total measure of risk and the equitable distribution of risk among the population centers. Besides, as to the general multiobjective model dealt with fuzzy goal programming, discussions are detailed whether its fuzzy optimal solutions are inner-related with weak efficient solutions and efficient ones as well. And to demonstrate the applicability of the model, a numerical example is provided using two different solution approaches. The results indicate that the weight additive goal programming can help to generate satisfactory solutions at a more acceptable achievement level.[著者文摘]
