摘要
主要研究模糊环境下土石方调配问题。通过对模糊环境下土石方调配系统组成、土石方调配关系的系统分析,以系统费用最低为目标,建立了模糊规划模型。基于可信性理论和不同的决策准则,建立模糊期望值模型、机会约束规划模型及相关机会规划模型,并设计了求解模糊规划模型的自适应遗传算法。算例证明了模型与算法的可行性。
This paper mainly studies earth-rock allocation problem in fuzzy environment.Based on systematical analysis of the composition and relations of earth-rock allocation system in fuzzy environment,the fuzzy programming optimization model for earth-rock allocation is established to achieve the minimum cost of the system.Furthermore,the fuzzy expected value model,the chance-constrained programming model and the dependent-chance programming model for a fuzzy earth-rock allocation problem are given based on credibility theory and different decision criteria.Then,a simulation based on adaptive genetic algorithm is designed to solve the proposed fuzzy programming models.Finally,the model and algorithm are proven reasonable through examples.
