In today's rapidly changing market environment, pricing decisions are no longer simple marketing tactics. Product pricing directly impacts sales volume and revenue, and incorrect pricing leads to inventory losses or opportunity costs. Dynamic pricing is a methodology that addresses these issues by presenting optimal prices reflecting real-time market conditions. But simply adjusting prices isn't enough. True dynamic pricing achieves completion when sophisticated sales volume forecasting combines with optimization algorithms.
Traditional pricing methods have primarily relied on historical sales data and competitor price analysis. However, this approach has fundamental limitations. First, it fails to timely reflect dynamically changing consumer preferences. Second, it inadequately considers complex interactions among market internal and external factors. Third, predicting appropriate pricing for new product launches proves difficult.
For new products especially, pricing becomes even more challenging due to absent historical data. Excellent product features paired with excessive pricing leads to market entry failure, while overly low pricing sacrifices profitability. Solving these problems requires systems that precisely model relationships between price and sales volume while comprehensively considering diverse market variables.
Effective dynamic pricing first requires accurately predicting sales volume changes following price changes. Models for this purpose are built on three core indices.
The Relative Price Index indicates how expensive or inexpensive a new product is compared to existing products. It's calculated by subtracting the existing product price from the new product price, then dividing by the existing product price. Positive values mean the new product costs more. Though this index appears simple, it becomes the starting point for understanding consumer price sensitivity.
The Product Differentiation Index quantifies how differentiated a new product is versus existing products. Calculating this index first requires determining the Consumer Satisfaction Coefficient. Using the Kano Model, classify each product attribute as attractive quality elements, one-dimensional quality elements, or must-be quality elements, then calculate consumer satisfaction. The crucial point here is that consumer satisfaction changes with price adjustments, so the Consumer Satisfaction Coefficient is calculated reflecting the Relative Price Index.
Each attribute's differentiation degree is evaluated in three stages. When identical to or degraded from existing products, classify as non-differentiated and assign weight 0. When improving existing attributes by 20% or less, classify as weakly differentiated and assign weight 0.2. When improving existing attributes by over 20% or adding completely new attributes, classify as strongly differentiated and assign weight 0.7. Multiply the Consumer Satisfaction Coefficient by differentiation degree to obtain attribute-specific differentiation indices, then synthesize these using Euclidean distance to calculate the final Product Differentiation Index. The calculated index undergoes normalization for modeling use.
The Demand Creation Index indicates how much more sales volume the new product generated compared to existing products. It's calculated as the ratio of new product initial sales volume minus existing product sales volume, divided by existing product sales volume. Positive values mean the new product sold more; negative values indicate decreased sales volume.
Train machine learning models using the calculated Relative Price Index and Product Differentiation Index as input variables, with the Demand Creation Index as the target variable. Adding environmental variables like major competitor price fluctuations, consumer purchasing pattern changes, seasonal factors, and consumer sentiment indices enables even more sophisticated predictions.
This three-index approach fundamentally differs from traditional demand forecasting. Previously, analyzing historical sales data meant predicting "we sold this much last year at this time, so this year will be similar." This method answers the question "how will demand change when price changes?" The Relative Price Index numerically expresses our product's price competitiveness versus competitors. The Product Differentiation Index quantifies the product value consumers perceive. The Demand Creation Index ultimately measures how much additional sales occurred in the market.
From a practical standpoint, these are the considerations when launching new products or adjusting existing product prices. Questions like "if we reduce price by 10%, how much will sales increase?", "if we're 5% more expensive than competitors but have better features, will consumers choose us?", "we've added new features—what price ensures adequate sales volume?" This model provides data-driven answers to exactly these questions. While machine learning seems complex, it's ultimately a tool that finds patterns in price and sales performance data from dozens or hundreds of products to predict the future. Think of it as systematizing and quantifying what a veteran demand forecasting specialist would judge intuitively through long experience.
Once the sales volume prediction model is built, the next step finds prices that can generate maximum revenue. This uses the exhaustive price search method. Predict expected sales volume for all possible price combinations, multiply price by sales volume to calculate revenue for each combination. Apply optimization algorithms based on this generated revenue data.
Optimization techniques include genetic algorithms, simulated annealing, and Monte Carlo simulation. Genetic algorithms mimic natural selection principles to find optimal solutions across multiple generations. Simulated annealing, inspired by metal annealing processes, finds global optima without getting trapped in local optima. Monte Carlo simulation performs optimization reflecting uncertainty through random sampling.
This optimization process enables optimizing not just single products but entire product line pricing structures. Derive price combinations that maximize revenue at the portfolio level by considering substitute or complementary relationships between products.
While dynamic pricing systems appear perfect theoretically, actual implementation involves various difficulties. The complex processes of data collection and preprocessing, model training and deployment, and periodic updates require too much time and cost for manual handling. ImpactiveAI has been developing models and systems to solve these problems.
Deepflow is the platform where these demand forecasting-centric technologies apply. It automates the entire process from automatic data integration through model training to forecasting. Data agents automatically collect and standardize data like dates, product IDs, categories, prices, and sales volumes by integrating with ERP systems. Subsequently, perform feature selection across 500 million possible combinations to find optimal variable combinations. The AutoML approach automatically selects the best-performing model by competing over 200 machine learning models.
Beyond deep learning or transformer models, various algorithms including hybrid machine learning models are embedded according to data characteristics, with optimal models selected based on data properties. When handling time series data particularly, LSTM-like recurrent neural networks or Transformer-based models precisely learn price change patterns over time.
Built on ImpactiveAI's 63 demand forecasting-related patents and AI models, Deepflow demonstrates verified performance at actual implementation companies.
Several important factors require consideration when building dynamic pricing systems.
Data quality matters most. Sales data, pricing data, and inventory data must be collected accurately and consistently. Many missing values or outliers significantly degrade model performance. When data is insufficient, synthetic data generation techniques can be utilized. Recently, generative AI is also being used to create consumer survey data.
Model retraining frequency is another important consideration. Industries where market conditions change rapidly require more frequent model updates. For products with strong seasonality, retraining models each season proves effective. Using automated platforms like Deepflow enables automatic model updates according to set schedules.
Reflecting business constraints is also essential. No matter how high the revenue an optimization algorithm predicts, it's meaningless if the suggested price is realistically impossible. Various constraints like minimum price policies, price ranges versus competitors, and brand positioning must be reflected in the model.
Validation through A/B testing matters too. Before full implementation of model-suggested prices, testing first in some regions or channels is safer. Continuously monitor and improve forecast accuracy.
Dynamic pricing methodology isn't simply technology for adjusting prices. It's a comprehensive business strategy that understands complex market dynamics, grasps consumer preferences, and makes data-driven decisions. The combination of AI-based sales volume prediction models and optimization algorithms makes realizing this strategy possible.
Particularly, the ability to predict appropriate pricing from new product launch inception significantly reduces corporate risk. From the product development stage, you can simulate market reactions, review various pricing scenarios, and establish optimal pricing strategies. This leads to development cost savings and improved market success rates.
If considering building a dynamic pricing system, keep both technical completeness and integration with business processes in mind. Leveraging solutions from specialized demand forecasting experts like ImpactiveAI shortens construction time while applying proven methodologies. Securing market competitiveness through data-driven pricing strategies—this is the innovation companies need right now.
