“…The authors identify critical characteristics of environmentally sustainable food systems and use these to develop supply chain structures that are environmentally sustainable and provide food security for low, medium, and high customer demand. Schweigman et al (1990) use operations research tools to address food insecurity in developing countries by determining the optimal amount of land that should be cultivated to prevent food shortage. Solak et al (2012) study tactical decision problems arising in nonprofit food distribution networks.…”

Modeling for the equitable and effective distribution of donated food under capacity constraints

et al. 2015

Mathematical models are presented and analyzed to facilitate a food bank's equitable and effective distribution of donated food among the population at risk for hunger. Typically exceeding the donated supply, demand is proportional to the poverty population within the food bank's service area. The food bank seeks to ensure a perfectly equitable distribution of food, i.e., each county in the service area should receive a food allocation that is exactly proportional to the county's demand such that no county is at a disadvantage compared to any other county. This objective often conflicts with the goal of maximizing effectiveness by minimizing the amount of undistributed food. Deterministic network-flow models are developed to minimize the amount of undistributed food while maintaining a user-specified upper bound on the absolute deviation of each county from a perfectly equitable distribution. An extension of this model identifies optimal policies for the allocation of additional receiving capacity to counties in the service area. A numerical study using data from a large North Carolina food bank illustrates the uses of the models.A probabilistic sensitivity analysis reveals the effect on the models' optimal solutions arising from uncertainty in the receiving capacities of the counties in the service area.

A bibliography of applications of operational research in West Africa

Int Trans Operational Res

View full text Add to dashboard Cite

There is considerable interest in the potential for using operational research (O.R.) in developing countries. One sign of this is the formation of new societies for O.R. scientists in countries and regions where no such society had existed. Since 2003, such societies have been formed in several parts of Africa. This paper focuses on West Africa, and presents a bibliography of papers relating to applications of O.R. in the nations of this part of the continent. The paper describes the way in which the bibliography was collated and discusses the overall picture that the list of papers presents of the state of O.R. in the 18 countries that are considered.

“…Nevertheless, there are many important factors that have not been included in this model. The study of fanners' strategies and food security is very complex and can only be approached by integrated studies of an interdisciplinary nature (Schweigman et al, 1990;Maatman et al, 1992). This study is only one component of such an approach.…”
