A Healthcare-oriented Recipe Recommendation Method with Arbitrarily Setting of Additional Ingredient Purchase Dates and Recipe Recommendation Dates

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 maximization of the healthcare score under the limits on the cost of purchasing additional ingredients and food loss when there are multiple optimal solutions. But in the previous research, only the consecutive additional ingredient purchase dates and the consecutive recipe recommendation dates are considered. In this research, new healthcare-oriented recipe recommendation methods with arbitrarily setting of additional ingredient purchase dates and recipe recommendation dates. Healthcare loss per 1 recommendation and healthcare loss per T recommendations are defined. Each healthcare loss is minimized by each proposed method under the limits on the cost of purchasing additional ingredients and food loss. 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.
