Recently, the closed-loop supply chain (CLSC) and its application to various fields have been an area of great interest. Despite the importance of CLSC, there remains a paucity of evidence on agriculture in this area. In this work, a CLSC network for the avocado industry is firstly designed by developing a bi-objective model considering the costs of the avocado industry and the social factor of job employment opportunities. The two objectives are the total costs minimization and job employment maximization in various opened locations. To validate the proposed model, a real case study in Puebla, Mexico, is addressed. The GAMS software and its CPLEX solver are utilized to find the best optimum solutions and determine the best locations to open different centers. The applicability of the proposed network is verified by conducting several sensitivity analyses on the important parameters of the problem. According to the obtained results, demand has the most effect on this network in which that a 25 percent decrease in demand can increase the total cost (the first objective) up to 40 percent and improve employment efficiency (the second objective) up to around 30 percent, simultaneously.

最近，闭环供应链（CLSC）及其在各个领域的应用引起了人们极大的兴趣。尽管 CLSC 很重要，但仍然缺乏关于该领域农业的证据。在这项工作中，首先通过开发一个双目标模型来设计鳄梨产业的 CLSC 网络，该模型考虑了鳄梨产业的成本和就业机会的社会因素。这两个目标是各个开放地点的总成本最小化和工作就业最大化。为了验证所提出的模型，在墨西哥普埃布拉进行了一个真实的案例研究。GAMS 软件及其 CPLEX 求解器用于寻找最佳解决方案并确定开设不同中心的最佳位置。通过对问题的重要参数进行若干敏感性分析，验证了所提出网络的适用性。根据获得的结果，需求对这个网络的影响最大，其中需求下降 25% 可以使总成本（第一个目标）增加高达 40%，并提高就业效率（第二个目标）高达 30百分比，同时。
