DDMRP Buffer Manager Skill

DDMRP Buffer Manager

Overview

The DDMRP Buffer Manager implements Demand-Driven Material Requirements Planning methodology for inventory management. It handles strategic buffer positioning, zone calculations, dynamic adjustments, and execution prioritization to create flow-based material planning.

Capabilities

Strategic Decoupling Point Identification: Optimal buffer location selection
Buffer Profile Assignment: Categorize items by lead time and variability
Buffer Level Calculation: Green, yellow, red zone determination
Dynamic Adjustment Factors: Planned and recalculated adjustments
Net Flow Position Calculation: Real-time inventory position
Execution Visibility and Prioritization: Color-coded supply priorities
Buffer Health Monitoring: On-target percentage tracking
Lead Time Compression Analysis: Identify lead time reduction opportunities

Usage

Buffer Positioning Analysis

Input: BOM structure, lead times, demand variability
Process: Identify strategic inventory positioning points
Output: Recommended decoupling points with rationale

Buffer Sizing Calculation

Input: ADU, lead time factors, variability factors
Process: Calculate zone sizes using DDMRP formulas
Output: Green, yellow, red zone levels by buffer

Execution Priority Management

Input: Current inventory, orders, qualified demand
Process: Calculate net flow position, assign priority color
Output: Prioritized replenishment recommendations

Integration Points
