When designing or evaluating Production Planning software (often part of an ERP or MES system), there are several core modules that are crucial to ensure efficient operations, resource optimization, and on-time delivery. Let’s break them down by functionality:
🧩 1. Master Data Management (MDM)
Holds the foundational data used across the entire planning process:
- Bill of Materials (BOM)
- Routing / Operations
- Work Centers & Machines
- Resources (labor, tools)
- Products / SKUs
- Suppliers & Lead Times
📝 Why it matters: Without clean master data, planning accuracy suffers.
📅 2. Demand Management / Forecasting
Handles the input side of planning:
- Sales forecasts
- Customer orders
- Market demand projections
📝 Purpose: Predicts what needs to be produced and when.
🏭 3. Production Planning (PP)
The heart of the system:
- Long-term planning (strategic)
- Mid-term planning (tactical)
- Short-term scheduling (operational)
- Capacity planning (RCCP, CRP)
- Material availability checks
- Rough-cut vs. detailed scheduling
📝 Goal: Create feasible, optimized production plans.
📦 4. Material Requirements Planning (MRP)
Calculates material needs and timings:
- Explosion of BOMs
- Procurement proposals (purchase requisitions, production orders)
- Inventory checks
📝 Ensures materials are available when needed without overstocking.
🧰 5. Capacity Planning / Finite Scheduling
Focuses on machine and labor constraints:
- Load leveling
- Bottleneck identification
- Finite capacity scheduling (sequencing)
- Shift planning
📝 Improves resource utilization and throughput.
🚀 6. Shop Floor Control / Execution (SFC / MES)
Handles actual production execution:
- Dispatching production orders
- Tracking progress and status
- Recording consumption and output
- Downtime and scrap tracking
📝 Closes the loop between plan and reality.
📊 7. Inventory & Warehouse Management
Manages raw materials, WIP, and finished goods:
- Location management
- Lot/batch tracking
- Inventory movements
- Kanban or Just-in-Time support
📝 Essential for real-time material visibility.
💰 8. Costing & Performance Analysis
Calculates and monitors production costs:
- Standard vs. actual cost
- Variance analysis
- Efficiency KPIs (OEE, utilization)
📝 Helps control and reduce production costs.
🔄 9. Integration with Other Systems
Integrates with:
- ERP (Finance, Procurement, Sales)
- SCM (Supply Chain)
- MES (Manufacturing Execution)
- PLM (Product Lifecycle Management)
📝 Ensures end-to-end visibility and consistency.
🧠 10. Advanced Planning & Optimization (APO) [Optional / Advanced]
Uses algorithms and AI:
- Demand-driven planning (DDMRP)
- Heuristic / optimization scheduling
- Scenario simulation (“what-if” analysis)
📝 Enables intelligent decision-making and adaptability.
⚙️ 11. Quality Management (QM)
Integrates inspection and quality checkpoints:
- In-process inspection
- Non-conformance management
- Traceability
📝 Ensures product quality meets standards.
📡 12. Reporting & Analytics
Provides insights into performance:
- Dashboards (OEE, throughput)
- Plan vs. actual analysis
- KPI tracking
📝 For continuous improvement and operational excellence.
