A Bicriteria Mathematical Programming Model for Nutrition Planning in Developing Nations
提出一个双准则数学规划模型，无需预先设定关键营养素的需求水平，而是生成一系列高效营养计划，并以哥伦比亚为例展示其应用。
Mathematical programming models for nutrition planning in developing nations typically involve the optimization of a single criterion function subject to resource and nutritional constraints. The nutritional constraints specify that the amount available of each nutrient for human consumption should meet or exceed some prechosen nutrient requirement level. However, fixed nutrient requirement levels are difficult to prespecify. In this paper, a bicriteria mathematical programming model is proposed which does not require planners to prespecify nutrient requirement levels for several key nutrients. Instead, the model generates an entire set of efficient nutrition plans which supply various amounts of these nutrients. To demonstrate the use and potential benefits of this model, an illustrative application to Colombia, South America is included.
