This study introduces a novel rolling forecasting framework for pharmaceutical sales, significantly reducing forecast errors by up to 75% and stock levels by 50%. The system enhances production planning and patient satisfaction.
Area of Science:
- Supply Chain Management
- Pharmaceutical Industry
- Data Analytics
Background:
- Accurate demand forecasting is crucial for pharmaceutical supply chain efficiency and production planning.
- Existing forecasting models lack a concrete, generic framework, particularly for the unique demands of the pharmaceutical sector.
- This study addresses the need for improved sales prediction and visualization in pharmaceutical manufacturing.
Purpose of the Study:
- To develop and validate a generic, rolling forecasting framework for pharmaceutical sales.
- To enhance supply chain managers' decision-making capabilities through accurate sales predictions.
- To integrate modern IT and business intelligence for visualizing forecast results and improving patient satisfaction.
Main Methods:
- A rolling forecasting framework was developed using Visual Studio C++ for optimal forecasting and Power BI for accuracy monitoring.
- The framework integrates three exponential smoothing methods, with the capacity for future expansion.
- The system was tested using multiple datasets from a pharmaceutical manufacturer.
Main Results:
- The proposed framework demonstrated superior performance in sales forecasting for a pharmaceutical manufacturer.
- Forecast errors were reduced by up to 75%, and stock levels decreased by 50%.
- The framework is currently in use by the company, with future integration into their Enterprise Resource Planning (ERP) system planned.
Conclusions:
- The rolling forecasting framework provides accurate future sales insights and turnover visualization.
- It enables more effective stock management and production planning, leading to improved supply chain efficiency.
- The system supports data-driven decision-making, ultimately contributing to better patient outcomes.

Median and Quartile Range: The median is calculated using the formula `=MEDIAN(range)', which provides the middle value of your data set. Quartiles divide your data into four equal parts. To find the first and third quartiles, use ‘=QUARTILE(range, 1)' and ‘=QUARTILE(range, 3)', respectively. The interquartile range (IQR), which...
