Location Master Service - Business Capabilities

Service Overview: The Location Master Service manages the warehouse location hierarchy, storage capacity planning, slotting optimization, and dynamic space allocation to maximize warehouse efficiency and throughput.

Architecture: Domain-Driven Design with Aggregate Pattern Technology Stack: Spring Boot 3.2, PostgreSQL, Redis, Apache Kafka Domain Model: Hierarchical location model with capacity constraints

L1: Warehouse Space Optimization

L1.1: Strategic Value

• Utilization: 90%+ warehouse space utilization
• Efficiency: 40% reduction in travel distance via optimal slotting
• Flexibility: Dynamic space reallocation based on demand
• Scalability: Support multi-site warehouse networks

L2: Core Capabilities

L2.1: Location Hierarchy Management

• Multi-level structure (warehouse > zone > aisle > bay > level > bin)
• Location attributes (type, capacity, restrictions)
• Dynamic location creation and deactivation
• Location grouping and virtual zones

L2.2: Slotting Optimization

• ABC analysis for fast/medium/slow movers
• Velocity-based slot assignment
• Seasonality adjustments
• Product affinity grouping

L2.3: Capacity Planning & Allocation

• Real-time capacity tracking (volume, weight, pallet positions)
• Space reservation for inbound receipts
• Overflow location management
• Blocked location handling

L2.4: Storage Rules & Constraints

• Product-location compatibility rules
• Hazmat segregation requirements
• Temperature zone assignments
• FIFO/FEFO/LIFO enforcement

Key Metrics

• Space utilization rate: 88-92%
• Slotting efficiency score: 85%
• Location accuracy: 99.9%
• Active locations tracked: 50,000+

Performance Targets

• Location query response: < 50ms
• Slotting calculation: < 5 seconds
• Capacity check: < 100ms
• System availability: 99.95%
