Abstract
Many healthcare-oriented recipe recommendation methods are proposed in previous research. In some previous research, the additional purchase cost and the food loss are minimized in addition to the minimization of the healthcare loss under the limits on the cost of purchasing additional ingredients and food loss when there are multiple optimal solutions. But in the previous research, the healthcare loss is minimized for only one person, even when targeting families. In this research, new healthcare-oriented recipe recommendation method considering families is studied. In the proposed method, the healthcare loss is minimized for families under the limits on the cost of purchasing additional ingredients and food loss. Weights for nutrients and family members can be set in the proposed method. The additional purchase cost and the food loss are also minimized in addition to the minimization of the healthcare loss when there are multiple optimal solutions. The effectiveness of the proposed methods is shown by some computational examples. This research is basic research, and future extended research is required.
