摘要
对于物流决策者来说,物流通道方案的选择需要对若干定性和定量因素进行综合权衡与比较,但是这些因素对备选方案的影响度会因时空、条件和决策者要求等因素而有所变化.根据物流运作的流程、特点和多目标模糊数学决策理论,通过引入变权因子,构造了在多个定性与定量决策因素约束下的基于变权的物流通道方案模糊决策模型,动态地反映通道方案中决策因素的重要度,通过计算与比较候选方案与理想方案的海明贴近度得出优选方案,并通过实例证明了模型结果与实际物流市场情况的吻合性.
It is necessary for logistics decision-makers to comprehensively measure many qualitative and quantitative factors,but theses factors usually vary with time,space,condition,demands of decisionmakers,etc.According to the process and characteristics of logistics and the theory of multi-objective decision making fuzzy,the fuzzy decision model of logistics channels schemes is constructed,which is based on variable weight and restrictions of many qualitative and quantitative factors.The model can dynamically reflect the importance degrees of correlative decision-making factors.Moreover,it can educe the optimized logistics channel scheme by calculating Hamming approach degrees between available schemes and ideal scheme.Finally,a demonstration proves the result accords with the conditions of logistics market.
