Abstract:

In response to the growing need for healthier, more personalized meal plans in assisted living facilities, we present a menu design framework to improve nutritional outcomes and resident autonomy. This approach balances competing objectives by considering guidelines from the United States Department of Agriculture (USDA) while also accounting for chefs鈥� expertise, dietary diversity, resident preferences, and cost constraints. We involve stakeholders such as facility managers, chefs, dietitians, and residents to create a practical model aligned with real-world operations and societal needs. Using Mixed Integer Linear Programming (MILP), we model this complex decision-making process, supported by clustering and principal component analysis, to capture and reflect diverse dietary patterns across resident populations. This approach uniquely integrates healthy eating guidelines (HEG) with the preferences of chefs and residents, aiming to ensure both nutritional value and meaningful choices for seniors. In two use-case scenarios involving over 300 menu items and three distinct diet profiles, our model is evaluated on preference satisfaction, adherence to dietary guidelines, and cost efficiency. Additionally, by incorporating data on residents' meal selection behaviors, we propose strategies that can improve long-term adoption and enhance the sense of autonomy in seniors, contributing to a higher quality of life in assisted living settings.
