Menu Engineering for Assisted Living Facilities
Abstract: Assisted living facilities are a rapidly growing segment of senior living communities providing end-to-end solutions comprising independent living, assisted living, nursing home care, and hospice. All these establishments contain (in addition to other facilities associated with living, exercising, learning, activities, etc.) dining services managed by an interdisciplinary (finance, nutrition, dietitian, kitchen operations, hospitality, and procurement) team of executives, each with their own objective while cognizant of the overarching organizational, operational, and financial metrics. The residents of these facilities consume most of their meals at these dining facilities, necessitating that the food served meets the complete nutrition, dietary, cost, and operational requirements. Thus, the menu (often rotating every few weeks) of food items must be carefully chosen to be efficiently procured, processed, and served while meeting the nutritional, dietary, and patron satisfaction constraints put forth by the corresponding stakeholder. We address this complex, unwieldy, and large multi-objective optimization problem using mixed integer linear programming. We demonstrate how menu planners and chefs can analyze their decisions regarding menu structures and evaluate alternative menu interventions to improve menus’ nutritional value while ensuring their residents’ autonomy in making food choice decisions. Along the way, we interviewed various stakeholders, identified their objectives and constraints, gathered the necessary data, formulated and solved the resulting optimization problems, and produced demonstrably effective menus.
