摘　　要：考虑到生鲜前置仓配送过程中时效性的重要程度,将时间满意度引入生鲜前置仓选址问题中,在综合考虑总配送成本和时间满意度的基础上,建立了生鲜前置仓选址双目标优化模型。采用极大极小归一化和线性加权处理,将双目标转化为单目标,并根据两种候选点选取方式的不同,分别用CPLEX和改进的遗传算法进行求解。最后通过算例验证了模型和算法的有效性,并比较了两种候选点的优劣性。Based on the importance of timeliness in the process of fresh pre-warehouse distribution,the time satisfaction was introduced into the fresh pre-warehouse location problem.On the basis of comprehensive consideration of the total distribution cost and time satisfaction,a dual-objective optimization model of fresh pre-warehouse location was established.The two targets were transformed into single targets by minimax normalization and linear weighting,and were solved by CPLEX and improved genetic algorithm respectively according to the different selection methods of the two candidate points.Finally,an example is given to verify the effectiveness of the model and algorithm,and the advantages and disadvantages of the two candidate points are compared.
