Understanding Demand Forecasting What is Demand Forecasting? Demand forecasting is the process of estimating future customer demand for a product or service based on historical data, market trends, and other relevant information. Accurate demand forecasting enables businesses to make informed decisions about inventory management, production planning, and resource allocation. Importance of Demand Forecasting Effective demand forecasting helps businesses: Reduce Inventory Costs: By accurately predicting demand, businesses can minimize excess inventory and associated holding costs. • Enhance Customer Satisfaction: Meeting customer demand promptly improves satisfaction and loyalty. • Optimize Supply Chain Operations: Efficient forecasting ensures that supply chain activities are aligned with demand patterns, reducing disruptions and enhancing overall efficiency. • Improve Financial Planning: Accurate forecasts contribute to better financial planning and budgeting, ensuring that resources are allocated effectively. • Demand Forecasting Techniques Recommended by thouCentric 1. Time Series Analysis Overview Time series analysis involves using historical data to identify patterns and trends that can be extrapolated into the future. This technique is particularly useful for products with stable demand patterns over time. | thouCentric | 1

3. 29 May 2024 Methods within Time Series Analysis Moving Average: This method smooths out short-term fluctuations and highlights longer-term trends by averaging demand over a specified number of past periods. • Exponential smoothing: This method prioritizes recent data while taking historical patterns into account by exponentially reducing the weights assigned to previous observations. • Seasonal Decomposition: This method breaks down demand data into trend, seasonal, and residual components to better understand and forecast seasonal demand variations. • 2. Causal Models Overview Causal models, also known as regression models, identify and quantify the relationships between demand and influencing factors such as price, promotional activities, economic indicators, and weather conditions. Methods within Causal Models Linear Regression: This method assesses the linear relationship between a dependent variable (demand) and one or more independent variables (factors influencing demand). • Multiple Regression: An extension of linear regression, this technique considers multiple independent variables simultaneously to provide a more comprehensive understanding of demand drivers. • 3. Machine Learning Techniques Overview Machine learning techniques leverage advanced algorithms and computational power to analyze large datasets, identify patterns, and make accurate predictions. These techniques are highly adaptable and can handle complex, non-linear relationships between variables. Popular Machine Learning Techniques Random Forest: This ensemble method combines multiple decision trees to improve prediction accuracy and reduce overfitting. • Support Vector Machines (SVM): SVMs classify data by finding the hyperplane that best separates different classes, making them suitable for both regression and classification problems. • | thouCentric | 2

4. 29 May 2024 Neural Networks: These models mimic the human brain's structure and function, making them capable of learning complex patterns from data and making highly accurate predictions. • 4. Econometric Models Overview Econometric models combine economic theory with statistical techniques to forecast demand based on economic indicators and variables. These models are particularly useful for long-term forecasting and understanding the impact of macroeconomic factors on demand. Methods within Econometric Models ARIMA (AutoRegressive Integrated Moving Average): This method models the time series data by considering its own lags and the lags of the forecast errors. • Vector Autoregression (VAR): This technique captures the relationship between multiple time series variables, allowing for a comprehensive analysis of how changes in one variable affect others. • 5. Judgmental Forecasting Overview Judgmental forecasting relies on expert opinions and intuition to predict future demand. This technique is particularly valuable when historical data is limited or when there are significant changes in market conditions that quantitative methods may not capture. Approaches within Judgmental Forecasting Delphi Method: This structured approach gathers insights from a panel of experts through multiple rounds of questionnaires, with feedback provided between rounds to refine forecasts. • Scenario Planning: This method involves developing multiple scenarios based on different assumptions and assessing their potential impact on demand. • | thouCentric | 3

5. 29 May 2024 6. Hybrid Models Overview Hybrid models integrate several forecasting methods to take use of each one's advantages and raise accuracy levels overall. By integrating different methods, businesses can create more robust and reliable forecasts. Examples of Hybrid Models Combining Time Series and Machine Learning: Integrating traditional time series methods with advanced machine learning algorithms can enhance accuracy and adaptability. • Blending Judgmental and Quantitative Methods: Combining expert insights with quantitative models can provide a more comprehensive view of future demand, particularly in volatile or uncertain markets. • Implementing Demand Forecasting Techniques Step-by-Step Implementation 1. Data Collection: Compile pertinent historical data, such as sales numbers, industry patterns, and outside variables affecting demand. 2. Data Preprocessing: To guarantee correctness and consistency, clean up and prepare the data. This may involve handling missing values, outliers, and data transformation. 3. Model Selection: Choose the appropriate forecasting technique(s) based on the nature of the product, available data, and forecasting objectives. 4. Model Training: Train the selected model(s) using historical data, ensuring that the model learns the underlying patterns and relationships. 5. Model Evaluation: Evaluate the model's performance using validation data and relevant metrics such as Mean Absolute Error (MAE), Mean Squared Error (MSE), and R- squared. 6. Forecast Generation: Generate demand forecasts for the desired time horizon using the trained model. 7. Continuous Monitoring and Refinement: Continuously monitor the model's performance and refine it as needed to ensure accuracy and relevance. | thouCentric | 4

6. 29 May 2024 Best Practices for Demand Forecasting Regularly Update Models: Continuously update forecasting models with the latest data to maintain accuracy and relevance. • Incorporate External Factors: Consider external factors such as economic indicators, market trends, and seasonality to enhance forecast accuracy. • Use Multiple Techniques: Employ a combination of forecasting techniques to leverage their respective strengths and improve reliability. • Validate and Refine Models: Regularly validate and refine models based on performance metrics and changing market conditions. • Engage Cross-Functional Teams: Involve cross-functional teams, including sales, marketing, and supply chain, to ensure a comprehensive understanding of demand drivers and improve forecast accuracy. • Benefits of Accurate Demand Forecasting 1. Enhanced Inventory Management Accurate demand forecasting helps businesses maintain optimal inventory levels, reducing excess stock and minimizing stockouts. This leads to cost savings, improved cash flow, and better customer satisfaction. 2. Improved Production Planning With reliable demand forecasts, businesses can plan production schedules more effectively, ensuring that resources are allocated efficiently and production runs smoothly.
