On a global scale, the retail sector incurs losses of $471.9 billion due to excess stocks and $634.1 billion from insufficient stocks. Forecasting demand aids businesses in precisely gauging the optimal quantity for procurement and production, aligning with customer demands. This enables enterprises to proactively plan production and enhance inventory management.
Demand forecasting algorithms make accurate predictions by analyzing sales data, market trends, and external influences. In doing so, they safeguard suppliers from supply chain disruptions and empower them to make informed decisions regarding inventory replenishment, supply chain management, production planning, and more.
How Algorithms Work in Demand Forecasting
Understanding the functioning of forecasting algorithms involves employing diverse methods and approaches and incorporating inputs from various sources into a layered recipe for creating forecasts in demand planning. The sequence of inputs, configuration of methods, repetition of steps, and outputs collectively constitute an algorithm.
While these algorithms can encompass multiple methods and inputs, they can be distilled into three logical operations: AND, OR, and NOT. Despite the potential for highly complex chains of operations, algorithms fundamentally rely on simple logical associations and a limited series of steps.
In practical terms, an algorithm could manifest as an exponential smoothing model, utilizing rules, parameters, and steps to generate outputs for the forecasting process, provided the need is well-defined, and the requisite data is appropriately formatted during the predictive modelling stage.
Demand Forecasting Algorithms for Inventory Optimization
- Clustering Analysis: This method aids in comprehending and analyzing data by segregating it into smaller, manageable subgroups, emphasizing attributes to facilitate improved predictions. The resulting classification model categorises new records and conducts predictive modelling within the specified subgroups.
- Descriptive Analysis: This technique narrates past occurrences, aiming to analyze and characterize them for predicting similar future events. By describing historical behaviour and applying predictive models to the resulting data, opportunities for operational enhancement and identifying new business prospects are framed.
- Outlier Analysis: This involves pinpointing abnormal values in a dataset to identify noise, enhance predictions, and detect anomalies. Databases may contain data objects deviating from the general behaviour or model, and isolating them helps better understand, determine impacts, or calculate responses.
- Factor Analysis: This technique aids in comprehending relationships and dependencies among various data variables, predicting how they will influence each other in the future. The information obtained allows forecasting future developments concerning the dependent variable based on the outcomes of associated factors.
- Time Series Analysis: This approach examines a series of values observed sequentially over time, enabling time-based predictions. Assuming the repetition of past data patterns like level, trend, and seasonality, this method constructs models using forecasted data to predict future patterns.
- Regression Analysis: This method facilitates understanding relationships and predicting continuous variables based on other dataset variables. It is specifically designed to discern meaningful connections among data variables, focusing on the interplay between a dependent variable and various independent factors that may or may not impact it.
AI Integration in Demand Forecasting
AI integration into traditional demand forecasting, as highlighted by a McKinsey Digital study, has the potential to reduce 30 to 50% of supply chain network errors. This AI-backed accuracy may result in a significant 65% reduction in lost sales attributed to various supply chain issues like stock-outs, leading to notable cost reductions in warehousing by 10 to 40%.
McKinsey estimates the impact of AI forecasting on logistics and supply chain management to range from $1.2 trillion to $2 trillion. By incorporating multiple variables in real-time, including internal and external data sources like demographics, weather, online reviews, and social media, AI takes demand forecasting to the next level, providing more precise forecasts applicable in warehouse management, operations planning, and various other scenarios. Furthermore, AI’s ability to predict demand for new products by analyzing data from similar products enhances forecasting accuracy and adaptability.
