摘要

为了实现联合国的零饥饿目标(可持续发展目标 2),在粮食银行生态系统尚处于初级阶段的发展中国家,非营利组织为运营粮食银行而采取的零散、孤立的举措通常效果不佳。由于潜在的等级制度、运营规模、捐助者类型以及受益人粮食不安全的严重程度,建立一个由捐助者、粮食银行、粮食回收和再分配机构(FRRA)以及受益人等实体组成的综合系统可能相当复杂。在这项工作中,我们提出了一个战略混合整数编程模型,用于设计一个综合粮食银行网络,以便为粮食无保障的受益人实现高效、有效和公平的粮食分配机制,同时考虑到他们的年龄特征和营养需求。我们通过最大限度地降低系统总成本来确保成本效益,通过收取罚金抑制食物浪费和需求得不到满足来确保效率,并通过采用五种平均主义方法来确保公平。我们结合真实数据和实际估算数据开展了一项案例研究,在印度德里设计了一个粮食银行网络,并进行了详细分析,为实践者提供了启示。具体而言,我们确定了粮食银行的初始能力、预算和战略到运营成本限制对解决方案的影响。在重要的观察结果中,我们的分析强调了何时可以采取收集更多即食食品的措施来缓解综合系统的压力,还有助于确定在哪些条件下投资能力建设比直接支出更符合受益人的利益。

Integrated foodbank network design: Model and a case study

To address the UN’s zero hunger goal (SDG 2), scattered and isolated initiatives by nonprofit organizations towards operating foodbanks are generally ineffective in developing countries where the foodbank ecosystem is at a preliminary stage. Establishing an integrated system comprising entities such as donors, foodbanks, food recovery and redistribution agencies (FRRA), and beneficiaries can be quite complex due to an underlying hierarchy, scale of operation, types of donors, and the severity of food insecurity of the beneficiaries. In this work, we present a strategic mixed-integer programming model to design an integrated foodbank network towards achieving an efficient, effective, and equitable food distribution mechanism for food-insecure beneficiaries while accounting for their age profile and nutritional requirements. We ensure cost-efficiency by minimizing the total system cost, effectiveness by discouraging food waste and unmet demand via charging penalties, and equity by adopting five variants of an egalitarian approach. We conduct a case study with a mix of real and realistically estimated data to design a foodbank network in Delhi (India) and present detailed analyses with insights for the practitioners. Specifically, the effects of foodbanks’ initial capacities, budget and strategic-to-operational cost constraints on the solution are identified. Among important observations, our analyses highlight when initiatives for collecting more ready-to-eat foods might be taken to relieve the pressure on the integrated system, and also help in identifying the conditions when investment in capacity building serves the beneficiaries’ interests better than direct spending.

期刊介绍: The International Journal of Production Economics focuses on the interface between engineering and management. It covers all aspects of manufacturing and process industries, as well as production in general. The journal is interdisciplinary, considering activities throughout the product life cycle and material flow cycle. It aims to disseminate knowledge for improving industrial practice and strengthening the theoretical base for decision making. The journal serves as a forum for exchanging ideas and presenting new developments in theory and application, combining academic standards with practical value for industrial applications.
