Blood platelets are a typical instance of perishable age-differentiated products with a shelf life of five days (on average), which may lead to significant wastage of some collected samples. At the same time, a shortage of platelets may also be observed because of emergency demands and the limited number of donors, especially during disasters such as wars and the COVID-19 pandemic. Therefore, developing an efficient blood platelet supply chain management model is highly necessary to reduce shortage and wastage. In this research, an integrated resilient-sustainable supply chain network of perishable age-differentiated platelets considering vertical and horizontal transshipment is designed. In order to achieve sustainability, economic cost, social cost (shortage), and environmental cost (wastage) are taken into account. A reactive resilient strategy utilizing lateral transshipment between hospitals is adopted to make the blood platelet supply chain powerful against shortage and disruption risks. The presented model is solved using a metaheuristic based on a local search-empowered grey wolf optimizer. The obtained results demonstrate the efficiency of the proposed vertical-horizontal transshipment model in reducing total economic cost, shortage, and wastage by 3.61%, 30.1%, and 18.8%, respectively.
血小板是一种典型的易腐年龄分化产品，保质期为五天（平均），这可能导致一些采集样本的大量浪费。同时，由于紧急需求和供体数量有限，特别是在战争和 COVID-19 大流行等灾害期间，也可能出现血小板短缺的情况。因此，开发高效的血小板供应链管理模型对于减少短缺和浪费非常必要。本研究设计了一个考虑垂直和水平转运的易腐年龄分化血小板的综合弹性可持续供应链网络。为了实现可持续性，考虑了经济成本、社会成本（短缺）和环境成本（浪费）。利用医院之间的横向转运采用了一种基于反应的弹性策略，使血小板供应链能够有效应对短缺和中断风险。所提出的模型使用基于局部搜索的元启发式算法求解，该算法受灰狼优化算法启发。所得结果表明，垂直-水平转运模型可分别将总经济成本、短缺和浪费降低 3.61%、30.1%和 18.8%。
