摘要:

针对农村地区农产品物流“最初一公里”存在的储藏难、损耗高的问题,以农产品主产区、特色农产品优势区、农产品集散区等具有冷藏保鲜需求的地区为例,提出基于本地冷藏、产地直发运营模式下的农村地区仓储保鲜冷链物流中心选址模型。针对鲜活农产品易腐、易变质,且对运输和冷藏要求高的特点,在选址模型引入时间约束。以运输费用、投资建设费用、运营费用之和最小为目标函数建立数学模型,利用Gurobi进行求解,寻找满足时效性要求的最优解,确保农村地区仓储保鲜冷链物流中心选址的合理性。对算例中的10个备选地址进行求解,结果表明建立7个冷链存储中心时的总经济成本最低,证明考虑产品类型、成本与时间的农村地区冷链物流中心选址模型具备可行性。

Abstract:

This study addresses the problems associated with the storage and loss of “the first kilometer” of agricultural produce logistics in rural areas. As an example, areas with cold storage requirements are considered and the location model of a cold chain logistic center is proposed under the operation guideline of local refrigeration, direct delivery from the origin for cold chain produce logistics in rural areas. Because fresh agricultural products are perishable, requirements for transportation and refrigeration are high. Therefore, the location model introduces time constraints. The objective is to minimize the total cost of transportation, investment, construction and operation. The model is solved using the Gurobi optimizer, achieving the optimal solution that meets time-related requirements and ensuring the rationality of the warehouse location planning results. Finally, ten alternative addresses are determines. Results show that the cost of building seven cold chain storage centers is the lowest. The findings of this study confirm the feasibility of the location model of the cold chain logistic center in rural areas by considering product types, costs, and time.

Key words: cold chain, location planning, logistics of agricultural products, rural area, fresh products
