    PubMed
    Summary

    This study developed a multi-echelon forecasting system for hospital menu-item demand, reducing forecast error costs by 40% compared to manual methods. The system improves accuracy for patient meal services up to 28 days in advance.

    Area of Science:

    • Operations Research
    • Healthcare Management
    • Statistical Forecasting

    Background:

    • Accurate demand forecasting is crucial for efficient hospital food service operations.
    • Existing manual forecasting methods can be labor-intensive and prone to significant errors.
    • Optimizing menu-item demand prediction impacts inventory management and waste reduction.

    Purpose of the Study:

    • To design and evaluate a multi-echelon statistical forecasting system for hospital menu-item demand.
    • To compare the cost-efficiency of the developed system against traditional manual forecasting techniques.
    • To analyze diet category distribution and menu-item preferences for improved demand prediction.

    Main Methods:

    • A three-echelon system was developed: patient census forecasting, diet category census estimation, and menu-item demand calculation.
    • Adaptive exponential smoothing and Box-Jenkins formulations were employed for statistical forecasting.
    • A cost function evaluated system performance over a nine-week period using eighteen weeks of historical supper data.

    Main Results:

    • The multi-echelon forecasting system demonstrated a significant reduction in forecast error costs, approximately 40% lower than manual methods.
    • Analysis of historical data provided insights into diet category distribution and menu-item preferences.
    • The system effectively forecasts demand for menu items from one to twenty-eight days prior to service.

    Conclusions:

    • Statistical forecasting systems offer a more cost-effective approach to predicting hospital menu-item demand compared to manual techniques.
    • The developed multi-echelon system enhances operational efficiency in hospital food services.
    • Accurate demand forecasting is essential for minimizing costs and improving resource allocation in healthcare settings.
