Assortment Optimization

← Back to Expertise

Overview

Assortment optimization determines which products to carry and where to place them to maximize revenue, profit, and customer satisfaction while respecting space, capacity, and strategic constraints. Our advanced algorithms leverage choice modeling, optimization techniques, and data analytics to create assortments that resonate with customer preferences and drive business performance.

Effective assortment planning balances variety (offering customers choice) with efficiency (managing complexity and costs). We help you find the optimal trade-off for your specific business context and customer segments.

Core Methodologies

Choice Modeling

Understanding how customers select products from available options:

• Multinomial Logit (MNL) Models: Predicting customer choice probabilities based on product attributes
• Nested Logit: Capturing hierarchical decision structures (category then brand then SKU)
• Mixed Logit: Modeling heterogeneous preferences across customer segments
• Attraction Models: Estimating demand as a function of assortment composition
• Substitution Patterns: Understanding product substitutability and complementarity

Optimization Formulations

Mathematical approaches to assortment selection:

• Knapsack Problems: Selecting products subject to space or budget constraints
• Integer Programming: Binary decisions (carry/don't carry) with multiple objectives
• Submodular Optimization: Exploiting diminishing returns structure
• Multi-Objective Optimization: Balancing revenue, profit, variety, and strategic goals

Data-Driven Insights

Leveraging analytics to inform assortment decisions:

• Sales and transaction data analysis
• Market basket analysis and affinity relationships
• Price elasticity and cross-price effects
• Competitive assortment benchmarking
• New product performance prediction

Assortment Strategies

Localized Assortments

Tailoring product selection to local markets:

• Cluster-Based: Grouping stores/customers with similar preferences
• Micro-Market: Store-specific assortments based on local demographics and preferences
• Space-to-Sales: Allocating shelf space proportional to category performance
• Climate and Regional: Adjusting for geographic and seasonal factors

Category Management

Strategic approach to product category decisions:

• Category role definition (destination, routine, seasonal, convenience)
• Good-better-best product tiering
• Brand portfolio management (national vs. private label)
• Price point coverage and price architecture
• Variety vs. duplication trade-offs

Planogram Optimization

Physical shelf space allocation:

• Shelf position and facing optimization
• Vertical and horizontal product placement
• Eye-level and reach considerations
• Cross-merchandising opportunities
• Compliance monitoring and execution

Lifecycle Management

Dynamic assortment evolution:

• New Product Introduction: Making room for innovation while managing risk
• Product Rationalization: Identifying underperformers for delisting
• Seasonal Transitions: Timing assortment changes for seasonal products
• Continuous Improvement: Regular assortment reviews and adjustments

Advanced Applications

Multi-Channel Assortment

Coordinating across retail channels:

• Online vs. in-store product selection
• Endless aisle and extended assortment strategies
• Omnichannel inventory visibility and availability
• Channel-specific assortment differentiation

Private Label Strategy

Optimizing store brand portfolios:

• National brand vs. private label mix
• Private label tiering (economy, mainstream, premium)
• Category penetration targets
• Profitability optimization with private labels

Promotional Assortment

Temporary assortment for events and promotions:

• Promotional product selection and depth
• Event-based assortment (holidays, back-to-school)
• Limited time offers and scarcity tactics
• Post-promotion cleanup and markdown optimization
