摘　　要：针对生鲜配送站多建乱建所带来选址成本居高不下的问题,在考虑固定建设成本、运营成本、配送成本的情况下,将新鲜度作为惩罚成本建立了模型的成本函数,引入竞争函数解决配送站建造位置过于拥挤的问题,以此为基础构建了多目标选址模型。收集宁波市数据形成算例,使用改进遗传算法对模型进行求解,得到了算例生鲜配送站的最佳选址方案,并通过与仅考虑成本情况下模型结果进行对比分析得到竞争和新鲜度对选址的影响。To address the problem of excessive and haphazard construction of fresh food delivery stations,we have developed a cost function for our model that incorporates the penalty cost of freshness,taking into account fixed construction costs,operational costs,and delivery costs.In order to address the issue of overcrowded locations for building delivery stations,we have introduced a competition function into the model.Based on these considerations,we have constructed a multi-objective site selection model.We have employed an improved genetic algorithm to solve the model and obtain the optimal site selection solution for the fresh food delivery stations in our case study.Furthermore,we have conducted a comparative analysis by comparing the results of our model considering both competition and freshness with the results obtained from a model that solely considers costs.This analysis provides insights into the impact of competition and freshness on site selection.
